Due to the need for frequent water use here, a non-powered pumping device is set up here, which is modified with a large oil drum, and the principle of pressure difference is used to continuously pump water from the ditch, but the drop of this non-powered pumping device pumping can not be too high, otherwise the iron drum will be deflated. And because one atmosphere can only pump water at a height of ten meters, once the drop of this non-powered pumping device exceeds ten meters, it needs to set up several more stages to complete the pumping.

Everyone also gathered around to see the strange, which many people did not expect, and at this time, the professor inside also directly popularized knowledge to the people around him who did not understand, and soon everyone understood the principle. Just by using the pressure difference, the water can flow like this.

At this time, the reporter's camera was naturally Kakaka recording these contents, and they also felt that this time they were really worthwhile. At this time, Su Ya in the team also looked at Li Zhao with light in her eyes, of course Li Zhao didn't notice it.

There is also a grass shed next to these pools, which is covered with a black cloth, Li Zhao also took everyone to take a look, at this time Li Zhao came back after graduation, and just got a small project, which is very simple, that is, mushroom planting, Li Zhao will pick the mushrooms from the mountain, seal and dry, extract the spores, and then point these spores on the steamed corn paste, and then cover them with steamed gauze.

Sure enough, a few days later, it was full of mycelium, and he planted these mycelium here, the substrate is soaked straw, corn cob or something, usually people come to sprinkle water or something, today I took a look, it's not bad, mushrooms have begun to emerge.

Many people are also surprised to see this, many of them do not know that mushrooms can also be grown. Seeing that the biology professor in the team here gave everyone another popularization of science. Li Zhao also told them that mushrooms, shiitake mushrooms, fungus and even Ganoderma lucidum can be cultivated, and the method is similar to this.

Then there is a livestock manure pretreatment area, which is also a pool, but it is much smaller here, and the manure of cattle, sheep and pigs will be piled up in the pool here, and then sealed to kill insects, and after being sealed for a period of time, it will be mixed with straw and grass and piled into the fermentation tank. Some strains are also added here, mainly nitrifying bacteria, and the same is sampling.

For this insecticide, Li Zhao almost broke his head, and a major problem in dealing with livestock manure is how to get rid of flies and insects. At first, of course, I wanted to use insecticides, but no, adding insecticides will also affect the follow-up projects, so I can only find a way to catch them, but how can the effect be good, for flies and insects, there are a lot of them, how can I choose the ones in small bottles.

Then it is smoked with wormwood, which has a little effect, but it is not obvious, and then it is a variety of tests, and finally a few effective methods are obtained, the first is to seal the pretreated manure, leaving only a small exhaust port, after inserting the bamboo tube, and then tie gauze on the bamboo tube, which is for the purpose of releasing biogas.

As for not building a biogas digester, it is because there is no money, but also because it is unsafe, those are pressure vessels, flammable and explosive, improper management, and prone to problems. The second is to cool down the livestock breeding site, which is easy to understand, the temperature is low, the mosquito activity is also low. The third is to ensure hygiene, whether it is the ground or the livestock themselves, to ensure that they are clean and hygienic. Finally, smoke it with wormwood from time to time.

After reading this, continue to walk forward, the front is the breeding area, the first is the chicken area, mainly because the smell of chickens is smaller than that of pigs and cattle. It is enclosed, and there are hundreds of chickens in it, but they are relatively ordinary local chickens, and there are no special breeds. At this time, Li Zhao also handed over the boiled earthworms to the person in charge here, and asked him to feed the chickens to everyone, mix these earthworms into the material, pour them into the stone trough, and then the chickens began to grab food, and everyone also understood Li Zhao's consciousness, earthworms are a delicacy for chickens.

As for why the earthworms are cooked, these biological experts all understand, in order to prevent parasites, after all, the source of material for these earthworms is feces, and it is difficult to ensure that there are no parasite eggs in them.

Li Zhao was also quite helpless to make the chicken farm like this, he originally wanted to raise it in a cage, but then gave up, the main reason is that there is no vaccine, medicine, etc. at this time, and it is too easy to get sick in a cage. The advantage of free-range farming here is that it is isolated from the outside world, and the personnel are often cleaned, and Li Zhao's request to these people is to clean every two hours. The weasel defense here is the strictest, and there are a few geese together, as well as dogs, and the dog leash will be released at night. Usually, except for special people, no one else is allowed to come here, just like this time, Li Zhao just let people look outside, and did not let people in.

Li Zhao also explained to everyone the reason why they were not allowed to enter, once the chickens were sick, it was likely that the whole army would be wiped out, but there were hundreds of chickens, the value was not low, and Li Zhao did not dare to take risks at will.

Further ahead is the pig farm, which is similar to the modern one, and Li Zhao also did not allow people to enter, but just looked inside through the fence, and everyone could understand it. After all, the value of these livestock is not low, if there is a problem, first of all, it will not be able to complete the production task, and secondly, it will also affect the New Year's pigs in the village, if it dies, the village can not eat the New Year's pork.

It's also very clean, and it's often rinsed with water. Li Zhao's requirements for raising pigs here are completely different from those of the outside world, these pigs are very clean, there is no other place to roll in the mud, and you can smell the smell of wormwood, which should have just been smoked with wormwood.

The non-powered pumping device here is pumping water all the time, through the gutters to let the water flow in the pigsty, to carry the temperature away, and these gutters also facilitate the use of water, which of course is separate from the gutters. The temperature here is not high due to the constant flow of water, and with the fumigation of wormwood, mosquitoes are relatively rare.

After the pig manure is collected, it will be sent directly to the pretreatment there, and the water that washes the ground will be discharged into a special pool, where Li Zhao also added bacteria, and there are several pools, which will be discharged in turn, and after being placed for a period of time, the water can be used to water the ground, and each time it is half of the water is pumped and half is left, and the fertilizer effect is quite good. Of course, the scale of pig breeding is relatively small, only a dozen, in addition to the task in the village, there are only a few left, and they can't afford to raise them.

And then there is the place where the cattle, donkeys, and sheep are raised, of course, these are separated, and the pig farm is similar, except that this side is not as small as the pig farming, it is the style of an ordinary cowshed, but it is also clean, the same smell of burning wormwood, and the same clean livestock. The temperature was also lowered by running water.

There are more than 20 cows, there are fewer donkeys, only a few usually pull carts, and there are only more than 30 sheep, and the livestock is still relatively small, the main reason is that they can't afford to raise it, although the cattle mainly eat grass, wheat straw and tardimile storage, but there is no food to match, he will lose fat, and he can't work to a certain extent, so the soybean cake after oil extraction is used to feed the cattle.

At this time, Li Zhao also took everyone to check the method of forage silage, of course, Li Zhao did not add anything, just silage, no way, many things he did not have, of course, he said the method of silage is very comprehensive, the silage of Lijia Village is completed in the cellar, and now there is also a part of silage, which is mainly the product of Li Zhao's experiment. These things are actually just a layer of window paper, as long as they poke it, these experts will understand it in seconds, and then they can explain the principles and benefits to the people around them more comprehensively, which is also an eye-opener for them today.

After everyone saw the livestock in Lijia Village, they also understood the difference between Lijia Village, the management of Lijia Village was relatively fine, and it felt the same as the military camp. However, this kind of management also brings more benefits, such as flies and insects, which is definitely a big problem at this time, but the farms in Lijia Village are circled, and they feel very few, and everyone probably knows the reason from their operation.

Finally, it is to measure the specific cultivation area of Lijia Village, because of the knowledge of the tools of Lijia Village, now everyone is very interested in the cultivation area of Lijia Village, this measurement is very accurate, and soon the data comes out, Lijia Village cultivates a total of 874 acres of land in autumn, you must know that there were only about 400 acres of land here, Li Zhao was reborn for only five years, and it is good to speak after going to college, and it takes a few years to open up nearly 500 acres. It will definitely increase next year, more than 1,000 acres or even more, and it won't take long.

Li Zhao also said to everyone at this time: "Our village will soon introduce tractors and other machinery, and the development of our Lijia Village will be faster at that time, don't look at our only more than 400 people, including a large number of old people and children, but once we start to implement mechanization, the output of our village is likely to increase tenfold." ”
