Chapter 055 The most cost-effective breeding

In modern times, earthworm farmers may not be able to make a profit. The biggest reason is that the market is saturated and the price of earthworms is rotten, and the selling price is not enough to cover the cost. Therefore, large-scale earthworm farming is generally used as a link in the production chain and integrated into livestock breeding such as chickens, ducks, fish, and pigs to achieve the goal of maximizing self-production and self-sales income.　　

It doesn't matter in this world...Anyway, the manpower, space, and feed (fermented cow dung) for cultivating earthworms are not cost-effective, as long as they are raised, it is a net profit.

After talking with Caogen patriarch about breeding, Xiao Yun and Caogen ran outside the industrial zone the next day to select a site, but found that the previous assumptions could not be established-indeed, the earthworm breeding farm can be effectively borrowed from here. In the geothermal area of the industrial zone, earthworms are creatures that like quietness. If the surrounding environment is too noisy and the ground shakes frequently, the earthworms will escape, and the gray dwarf smelting site you want to reduce the noise is unrealistic... 　　

It's nothing but Xiao Yun only Can change direction and change the earthworm farm to the greenhouse area-potatoes, wild ginger, and sweet potatoes grown in the greenhouse cannot grow in a climate of more than ten degrees below zero and dozens of degrees in winter, and the vegetable greenhouse needs to be dug out and surrounded The annular flue and the wall at the bottom of the greenhouse are interlayered. Through the flue and interlayer heating, the temperature in the greenhouse can be maintained at about ten to twenty degrees. The same heating system also supplies the mushroom house in Saar. It only takes a little effort to expand the heating system to benefit earthworm breeding.　　

Earthworms are afraid of cold and heat. The farm also needs to dig out a semi-underground structure similar to a mushroom house. Xiao Yun and Caogen patriarch selected a location and called a work team to start construction.

It has been snowing for ten days, the earth has been frozen, and the outdoor temperature during the day is also more than ten degrees below zero. In this kind of weather, the cold goblin used to hide below ten meters to barely stay awake and not dormant. Now there are Snow Werewolves. The sweaters and animal skins given can only squat in the house and can't come out to move around. Fortunately, the gray dwarves cast and forged a lot of iron tools, such as hoe, shovel, hammer and steel drill for driving stones, etc. The work team led by Dashui, Qingcao, and Languo are not slow in construction.　　

Hmm...Compared to using claws to plow the soil last winter, this year is not too easy. Although there will still be the problem of frostbite, there are too many people anyway, and the shift can't be missed.

While excavating the foundation, the semi-underground space is dug out. The underground space is surrounded by a circular flue with mud bricks. When laying the walls, it is also necessary to leave an insulating interlayer-the wall interlayer can effectively insulate in the summer and in winter.

Discharging the hot smoke into the interlayer can also effectively increase the temperature in the breeding shed-in weather where the outdoor temperature is often tens of below zero, it is not enough to rely on the underground flue ring to keep the indoor temperature of the greenhouse at about 20 degrees.

An earthworm breeding shed with a length of 30 meters and a width of 7 meters was completed in the same specifications as the vegetable shed. There is a channel of 1.2 meters in the middle of the shed, and the two sides are used as breeding beds.

Each bed is separated by brick walls with a width of about two meters. Open, leave a palm-wide drainage ditch and summer ventilation channel between the bed; the feeding bed is built with fermented mature cow dung and humus (including chopped weeds, leaves, wheat stalks, leaves, and rotten vegetables) as the foundation Feed, feed must be fermented mature, the whole is black, without pungent odor, the base material must be put in to ensure a certain amount of fluffy, not too tight, to ensure that the base material has air permeability.

The decomposed feed is piled loosely to a height of about 20 centimeters, covered with pig urine bubble on the pottery tube, and then squeezed with water impermeable pig skin, and the burned warm snow water is sprayed into the base material, when the humidity of the base material In order to pinch the fingertips to see the water, you can put in the earthworms and start breeding.　　

There is no place to buy good breeds in this place. To feed the earthworms, I can only catch them by myself. In winter, earthworms mostly burrow into the deeper soil to dormant, and you can find the dormant earthworms hidden in the soil by digging up to about one meter from the river bank... Anyway, Xiao Yun is not clear about the types of earthworms, and doesn't care what they dig out. What kind of earthworms are, all of them are framed and brought back to the breeding shed, and they are sprinkled on the breeding bed with soil blocks.

Xiao Yun and the patriarch Caogen stared at the breeding bed. The indoor temperature was about 20 degrees, there was no light, and there was a certain degree of ventilation in the breeding shed. The small, dormant earthworms gradually woke up, instinctively moistened. Drilling in the base material-this is considered a successful seeding. "Keep indoor temperature well and ventilate three to four times a day. Pay attention to check the humidity of the material bed. In this weather, spray water once every five days, and once a day in summer. Pay attention to whether there is any accumulation of water at the bottom, and check if there is any. Is the drainage ditch below blocked..." 　　

Xiao Yun demonstrated spreading wheat stalks on the surface of the feeding bed as a base material to keep warm and moisturize. While talking to the grass roots about the feeding points, the grass root patriarch felt dizzy after only hearing a few words. Rising, waved his hands again and again: "I can't remember what you said so much, just tell me a little bit."

...Well, in short, to feed this thing, the indoor temperature and humidity must be maintained. In this regard, you can ask Thrall's experience. The temperature and humidity of growing mushrooms are similar to that of earthworms." 　　

"Okay, this me Remember." Caogen walked up and touched the edge of the base material pile, "This food for earthworms should be moist, but it should not be wet to the bottom. If there is water, check the drainage pipe under the material bed."

"Yes." Xiao Yun compared his thumbs, "Next comes indoor ventilation. Earthworms can run if they are stuffy. You must open the door at least three times a day to let the air out. Do not remove the grass shed at the door during ventilation. You must block the light. Earthworms are afraid of light. Yes, this is almost the same as that of Saer's cultivation of enoki mushrooms." 　　

Caogen noted this point, and Xiao Yun led her to continue busy collecting earthworm seeds... Breeding is a long-term work, and patience, care, and perseverance are indispensable. It is unscientific to hope that Caopgen can get through the two veins of and point out the breeding talents after one or two talks. It is unscientific to let Caogen experience the process from planting to harvesting in person, which is considered as a successful teaching.

Anyway, here in Xiao Yun, among the Snow Werewolves, no, Caogen with no inferior IQ compared with humans can't be understood at a glance. When Xiao Yun was busy with other things, he did not say that only ask Caogen breed earthworms,

he have to come and check the activity of the earthworms every day.

After ten days later, when Xiao Yun and Caogen checked the feeding bed together, they found that there were more worm feces at the bottom (the difference between worm feces and base material is more obvious when you look closely. The worm feces are more like clumps of soil).

Then began to add feed for the first time-first turn the feed bed loosely, shovel out the worm manure at the bottom, and then spray the raked feed with water mist to increase the humidity and spread it on top of the base material. The thickness is about centimeters.　　

Earthworms eat the same weight of feed as their own every day, and half of them are excreted as feces. When adding feed, remember to eradicate the feces in time to avoid infection by the earthworms and not to be lazy.　　

Xiao Yun inspected the worm feces that were shoveled out, and did not see the cocoons, so he poured the worm feces in a collection place outside the greenhouse, and put them into use when they were farming in the coming year.　　

In a natural environment, earthworms will certainly not produce cocoons in winter. They can produce cocoons all year round in a greenhouse environment. This is also the advantage of breeding. When adding feed for the second time, Xiao Yun found earthworm cocoons in the worm feces.

Patriarch Caogen was very happy, staring at the cocoons of earthworms smaller than wheat grains for a long time, and remembered their image (smooth surface, black, brown or yellow semi-transparent cocoons, a bit similar to cocoons, but very small ), and then together with Xiao Yun put the earthworm cocoons mixed with the worm feces into a wooden box, and move them to a place where the temperature is lower (about 15 degrees) in the greenhouse for incubation.

Add ten centimeters of feed to the top of the hatching pile, about 20 After days, a large number of earthworms hatched from the cocoons. (The temperature required for incubation is slightly lower than the temperature in the growth period. The incubation rate is the highest at around 15 degrees, which is close to 90%. If the temperature is the same as the growth period, 20~26 degrees, the incubation rate is only 40%.) 　　

Maintain temperature and humidity In good conditions, one cocoon can hatch several earthworms. At this time, the density of earthworms in the hatching pile is extremely high and needs to be reared in piles. At the same time, mature earthworms that have been reared for 40 days can also be harvested and free up for rearing bed.

There are many ways to harvest earthworms. Xiao Yun imitated the method of the live broadcast of the young couple. He transferred the base material of the breeding bed to the outdoor concrete floor, and scraped the base material from top to bottom. The earthworms can drill down layer by layer because of the instinct to avoid light. , Hiding at the bottom of the base material, you can focus on harvesting.　　

The vacant material bed is supplemented with the base material, and one third of the newborn earthworms in the hatching pile are divided into it to continue breeding. A hatching pile can be divided into three or four new beds depending on the number of hatching. (Each bed of new material can supplement part of the earthworm species collected in the wild for hybridization, to avoid degradation of earthworm species inbreeding) 　　

The harvested earthworms are placed in the sun for 20 minutes to die, or cut into sections or dry and grind. Livestock feed directly... (The dried earthworms seem to be a kind of Chinese medicine) 　　

The surplus earthworm breeding on the earth is very cost-effective in this world, and the earthworms raised are themselves excellent livestock feed. During the breeding process The produced earthworm manure is also a top-quality fertilizer. Compared with the breeding cost which is almost equal to nothing, it is simply a huge profit.　　

The first batch of earthworms harvested was dried and cut into pieces and bagged. Patriarch Caogen rubbed his hands excitedly: "Ayun, these earthworms can make our pigs plumper, right?"

The wild boar that has been slapped for a while and then killed is really delicious. After eating it once, the status of pork has been ranked ahead of mutton in the minds of the people.

"Yes, this thing is better than alfalfa." Xiao Yun nodded his head. "In the future, we will raise pigs with more fat, fat, lean and more delicate meat. It depends on this." 　　

Caogen is so happy. Hopping to find the cubs who are responsible for feeding livestock to fetch the earthworms...　　

Xiao Yun was also very happy to look at her excited appearance, interest is the best motivation-don't you think earthworms are disgusting and like it so much? Those raised are not ordinary people, anyway, he braced his scalp to support him all the way.

The green dragon came here twice in the past forty days, and each time it was frozen like a idiot. The green hair was covered with ice, but it was still very strong to satisfy his appetite... Xiao Yun looked at him. He was embarrassed to work with two pipes of snot and forced to be cold. He braved the extremely cold air to work, and let him go back after having a meal; the flying bun was also taken away by him on the day he was built, along with other routines.

Jewelry, such as bracelets, rings, necklaces, foreheads, etc., use up all the gold, silver and gemstones given by this petty ghost. He thought that all the jewelry was given to him, there should be no excuse to come again, but on the day when he harvested earthworms for the first time, Xiao Yun heard the gray dwarf's exclamation and looked up, the green dragon came again—this time he knew it.

It was cold, useless in human form, and turned into a big green lizard flying over.

This big green lizard landed on the ground leveled by the snow wolves in front of the tribe, leaving a particularly exaggerated indentation on the snow... and then jumped up into a human form, and rushed into the heated activity room. Xiao Yun followed up and took a look. This guy was hurriedly putting on clothes—not the high-necked robe, but the thick white-haired bear fur coat.　　

Bearskin coat with bare buttocks... right!　　

"Uh..." 　　

"I'm inspecting the territory, Ahchoo, stop by and take a look." Before Xiao Yun could speak, the green dragon looked over with a serious face. Well, if this guy hadn't been so cold that his face was green and white, and white and blue, Xiao Yun might believe it.　　

"...Welcome, we are honored." What else can Xiao Yun say.

Bring the warm soup on the stove, and prepare to bring the bean curd for adding vegetables to the tribesmen in the evening. Put the pickled vegetables and salted radish on a plate, and then heat up the leftover pickled steamed buns and fried meat patties at noon to "welcome the guests" feast. It's just like living together... The decent hospitality meals are served with plates and dishes! When my family eats, they are not so poor.

This time this guy finished eating and didn't say to leave. I didn't know where he took out the book and sat in the warm activity room to watch it leisurely. Xiao Yun, who was with the guests, looked at it and thought that he would come here and have a meal. It's a bargain, it still want to eat at night, and I don't bother to worry about it, so I found an excuse to go out to do his business-his time is precious, so good!

He walked out here, and there secretly took his eyes to aim at his green dragon, but he was greatly relieved... His castle protected by the enchantment of magic is so tall that it's right, but it's so cold~ in previous years. In winter, he always nestled in the depths of the castle to sleep.

Few back and forth, so cold and silly, only mixing a meal really not cost-effective, how can he have to mix two meals!" The green dragon secretly made up his mind, if the snow wolf man cub wanted to drive him away, he would ask the cook-this matter was fooled by the other party last time, but he did not forget it!

Xiao Yun, who went straight to the industrial zone, said, "Ahchoo! Ahchool! Damn it, don't that stupid dragon catch a cold and infect me?"

In the collective bedroom diagonally across from the activity room, Sal & the four manul cubs stared attentively looking at the door of the activity room, they didn't see the green dragon coming out for a long time.　　

One of the cubs looked up at Sal: "Sal, isn't the green dragon going away?" 　　

Sal: "..." How do I know!

The five sighed together...The activity room was occupied by the green dragon, and none of them dared to go in~

One of the cubs looked up again: "Sal, do you teach us to grow mushrooms?" 　　

Sal immediately turned his head away and pretend his didn't hear them

The manul cubs were unhappy: "We taught you to weave blankets, but you refuse to teach us to grow mushrooms." 　　

Sal went back to where he slept and took a fur coat and put it on: "Sorry, let me go check the mushrooms."

The manul cubs stretched their middle fingers at Sal's back together—that's what Ayun did when he sent the pesky green dragon!　　

In the industrial zone, Xiao Yun, who was discussing ploughing with Baru,

"Ahchoo!" 　　

"Ayun, have you caught a cold?" Baru was concerned.

"It shouldn't, my nose is not blocked." Xiao Yun was also very strange, "Forget it, don't talk about it, Baru, do you think I recommend processing like this?" 　　

Gray dwarves of course make plows, but they do. It is the kind of heavy plow that is cumbersome and huge, which allows several cows or horses to be dragged together...Because the science and technology trees in this world are not related to agriculture, the aborigines can only cultivate on the flat plains, and the world is structured. The country adopted a system of enfeoffment of land power, and there is no small-scale peasant economy. The development of plows is naturally to facilitate the cultivation of the great plains. The system of land power enfeoffment was eliminated after the Han Dynasty in China. It is the feudal system of feudal power (the alternation of the two power systems can be seen from the history of the demise of the family. Everyone knows that the rise and fall of feudal dynasties are inseparable from the out-of-control of land annexation, and the system of feudal power of land does not exist in land annexation at all, because The production resources of land are all in the hands of the power holders, and all farmers are serfs.) The small peasant economy prevails, and naturally all kinds of plows will be born.

Of course, this is not to say that there is no light plow in this world. For example, the tauren uses a light curved plow...

Curved plow is not bad, but after thinking about it, Xiao Yun still hopes to put more effort on the plow. After all, there are few people in the Snow Werewolf, and there is no way like the tauren to pull the curly shaft to plow the land alone, so Xiao Yun asked whether he could make a split-type plow—a split-type plow on the earth that is pulled by a tractor. Xiao Yun once saw it in the countryside. The scenes such as the rows of fans, five plowshares on the same horizontal plane cutting, breaking, and turning over the soil and weeds were deeply impressed in his mind, playing the super drag of the snow werewolf in the wolf-like form. Power and traction plows for plowing work, the efficiency is just above the ground.

Xiao Yun said happily, while Baru was frowning...You clearly said that you don't like heavy plows, but there is a difference between the kind of plows you require and the heavy plows—heavy plows are half of the wood structure at best, and you have all the requirements. The steel structure is heavier!

However, the sketch of the split plow that Xiao Yun reluctantly drew from Balu is also very heartwarming. The heavy plow is cumbersome and is not flexible enough to be able to turn. This fan-shaped plow is spread out and the drag force is concentrated on one point. It's also heavy, but at least it won't even turn the face.

"We can try to make a set of molds, first make a sample and take a look." Baru touched his chin cautiously, "There is no way to form such a large all-steel plow in one piece. We can only make the components and assemble them... we You have to study the assembled parts first."

The forging process of the gray dwarf is not only forging, not to mention laborious, time-consuming and low output are the problems. If conditions permit, they also have the skill points of mold casting-making molds with mud and sand, and pouring molten iron into casting, is more efficient than hammering one by one. I don't know where it is going.　　

Of course, when making some high-performance ironware, forging is still needed. The overall density of cast ironware is poor, and the impact resistance is not strong. The part of the plowshare coulter must be forged with great effort. Xiao Yun nodded, and immediately took out the wood chips and pottery clay he had brought with him: "It doesn't take so much trouble to figure out the components. You can figure out the general structure by building a model." 　　

So the two of them were busy. Hand-made models are played in the busy industrial area...　　

It's really not easy to figure out the structure and components, even if it's a relatively simple structure, it's not that easy, what shape is it? What kind of function does his coulter have, and where the shoveling thing is designed, these are things that have a technical threshold for laymen to figure out.

The dizzy Xiao Yun and a group of gray dwarves returned to the tribe to eat. When they saw the green dragon occupying the mobile room waiting for the meal, their eyes suddenly flashed brightly-wait, this guy can use magic out of thin air To make a rope for tying wild boars, the rope is still tenacious, and adult wild boars can't get rid of it. Wouldn't it be easier to use the ability to create objects out of thin air to model objects and analyze parts than to use wood chips and clay?　　

Baru saw the green dragon shrinking his neck subconsciously, looking up at A Yun who could give them a sense of security, and then he saw... Ayun's face showed a not-so-kind evil smile, striding towards the green dragon...

Baru: "??" 　　

Xiao Yun smiled like a flower (...), eagerly approaching the green dragon: "Your honorable lord, it's a blessing for my clan to know a dragon like you, but you can only come occasionally. Once, we had to go back after a short stay. This is really regrettable for us..." 　　

Green Dragon: "??" 　　

The longevity of the dragon clan is placed there, no matter how stupid you live for a long time, you will learn lessons. At that time The green dragon, who was coaxed by Xiao Yun and flew for more than one day and two days to catch wild boars, can naturally recall it after thinking about it...but he did enjoy the offerings of the snow werewolf, and he felt that something was wrong. There is no reason to be angry.　　

This time Xiao Yun gave flatter on Xiao Yun. The green dragon sounded comfortable and comfortable, and he must be alert in his heart-what does this guy want me to do this time?
