It was still early, only a little after nine o'clock, Li Zhao came to Director Yang's office, and in order to receive his allowance, the allowance was issued by the rolling mill, but in order to be less conspicuous, he received it from Director Yang alone. Otherwise, Li Zhao directly received a salary of more than 100 yuan, then it would not be fried, he had only been here for ten days, and he had received hundreds of yuan directly, who could balance his heart.

After sitting down and taking the allowance, Li Zhao chatted with Director Yang about ecological agriculture. Li Zhao's ecological agriculture is based on earthworm farming as the core of ecological agriculture, and many other matters are carried out around this one. In addition to a part of the straw produced by farming, which is used for cooking and part for feeding livestock, the rest is directly chopped, and since there is no crusher, it can only be used with a guillotine.

The chopped straw is mixed with livestock manure, etc., sealed for a few days, and then mixed with bacteria to ferment. After the fermentation is completed, it is used to feed the earthworms, and the resulting earthworm soil is collected and kept for the fertile field. The cultivation of earthworms is also simple, as long as the temperature and humidity are controlled and the PH value is guaranteed, there is basically no big problem, of course, it is necessary to prevent some animals from stealing food, earthworms exist very widely in nature, and many animals eat this.

Earthworms can be used as protein feed for chickens, ducks, and pigs, and Li Zhao has been working on them in his village for three years. In the first year, Li Zhao led the little children in the village to dig for ten days, and finally dug out dozens of catties, looking like there were five or six varieties, Li Zhao directly cultivated these earthworms that were obviously different, and finally chose a red earthworm that can grow to the size of chopsticks to breed, this kind of growth is the best, and the adults are also relatively easy to sort.

Now the earthworm has multiplied to the scale of thousands of catties, and the village is still continuing to expand the scale of breeding. Li Zhao went back last time and also took a look, and the effect was not bad, both the growth rate of chickens and the egg production rate were significantly improved.

In the future, with the expansion of the scale of earthworm breeding, duck raising, pig raising, sheep raising, cattle and fish raising projects can be added to it, in fact, these have been added, but now it is only used to process the manure of these animals, and has not been fed to pigs, ducks and fish. Earthworms are the ultimate decomposers of these breeding projects, and the farmed earthworms are washed and cooked and used as protein feed for chickens, ducks, pigs, and fish. In winter, it is also simple, as long as the earthworm breeding place is covered with a thick layer of soil, and the waterproof can keep the earthworm warm for the winter.

After the fish farming project is added, the mud from the fish pond can also be cleaned once a year and used as fertilizer in the field. In this way, an ecological cycle is formed, and the organic matter produced in the field is used to the maximum extent, and the inorganic matter that is eventually decomposed is also used as fertilizer back to the field. Of course, there are also difficulties, mainly strains, Li Zhao only selected some species, which may not be considered comprehensively, these are needed to be studied by follow-up agricultural people.

Then Li Zhao calculated the account for Director Yang, their village now planted about 800 acres of land, and the straw produces more than grain, so there are at least 400 tons of straw per year in two seasons every year, of which half is used to raise earthworms, and two layers are converted into earthworms, and half of the earthworms are converted into meat, then in the end, 20 tons of livestock can be produced. According to the seven-layer meat production rate, there are also 14 tons of meat, according to the market price of 7 cents a catty, it will create 23,800 economic benefits, if it is distributed to the villagers, Li Zhao and their village will have more than 400 people, each person can share 50 or 60 yuan, and this income can directly make Li Zhao and his village afford to buy a tractor.

Of course, this is theoretical data, and if Li Zhao and his village want to achieve this effect, it is estimated that it will be achieved next year at the earliest, and the year after next at the latest. Then Li Zhao introduced the country's grain output to Director Yang, 61 years is actually very low, affected by natural disasters, the output is only less than 140 million tons, and next year's national grain output, under the effect of Li Zhao's new set of agricultural machinery, is likely to directly reach 200 million tons, so the straw is calculated according to 200 million tons, if it is used, how much benefit will it have?

This era is a good time for the development of ecological agriculture, after the communization of the countryside, it has become a small farm, and the villagers are more like farm employees, so as long as the work distribution is reasonable, management in place, this kind of ecological agriculture can definitely be developed, and the income after development is also very considerable, and it can definitely reach more than five times the current income.

Think about it 60 years later, the annual output of 500 million tons of grain, then there will be at least 500 million tons of straw, if these can be used, then it can produce tens of millions of tons of meat, but also can solve the problem that a large number of straw can not be processed. In this regard, bald eagles make better use, and a large part of their straw is used to make alcohol, which is used as an additive to fuel.

And how much have we wasted? These wasted organic matter, how much carbon dioxide synthesis sugar factories can compare, that is 100 million tons of organic matter, think about it can't help but sigh. What's more, it also brings a lot of pollution problems, and the inorganic matter taken away by the straw can not be returned to the field, and more chemical fertilizers need to be used, and the abuse of chemical fertilizers will make the water body over-trophied, making the original fish pond become a stinky ditch.

The production of chemical fertilizer, the pollution is also huge, in the case of the best quality lump coal, a ton of fertilizer also needs about 1.4 tons of coal, and inferior lignite, it takes more than 1.8 tons, the country produces more than 50 million tons of fertilizer every year, of which more than 30 million tons are used in agriculture. Hundreds of millions of tons of coal will be burned to make these fertilizers, and more than 5 billion kilowatt-hours of electricity will be used.

Thinking of this, Li Zhao wants to change this era even more, there are many good places after sixty years, but there are also many bad places, Li Zhao sees an opportunity to change here, and wants to give it a try.

When he heard the figures calculated by Li Zhao, Director Yang was also a little speechless, and then asked: "Then which places are suitable for earthworm farming?" ”

For this problem, it is even simpler, Li Zhao replied: "As long as there are earthworms living in the wild, earthworms can be raised, and in addition to desert areas, I estimate that there are earthworms living in the whole country." In other words, earthworms can be farmed in most parts of the country. However, I don't know the situation on the plateau, and the grassland is probably not needed. ”

Hearing this, Director Yang couldn't sit still, and ordered the secretary to prepare the car, and he pulled Li Zhao to the mechanical department.

Li Zhao is also helpless, as long as there is no problem with Director Yang, when the news is reported, let the family write it comprehensively, and it can highlight the rolling mill itself, and those who are interested in agriculture will naturally visit their village, so that it can be spread. Director Yang and Li Zhao had different ideas, Director Yang saw a huge credit, and when he arrived at the Machinery Department, Director Yang directly found the leader and told Li Zhao about ecological agriculture.

Li Zhao directly calculated the national data this time, and next year's total grain output is calculated at 200 million tons, with at least 200 million tons of straw. Because it involves the whole country, Li Zhao gave a proportion of one-tenth of the straw, and finally concluded that the use is good, and it can produce 14 million tons of meat every year, which is only counting the transformation of earthworms, of course, this is impossible, when feeding, a part of the grain must be fed, so how much will this number be doubled.

At this time, the leader couldn't help but rub his eyebrows, this Li Zhao is really able to toss, especially after hearing that Li Zhao has now raised thousands of catties of earthworms in Lijia Village and started feeding chickens, he also understands that this is a huge credit. I also understand the purpose of Director Yang to bring Li Zhao here, but the leaders also know that this project is obviously very necessary to promote, or to promote it no matter what.

At this time, the leader no longer hesitated, and pulled Li Zhao to the Ministry of Agriculture, and this time the Ministry of Agriculture owed a big favor. The front agricultural machinery is the Ministry of Machinery to rectify, and now with the project of ecological agriculture, the Ministry of Agriculture owes a sea of favors this time.

And is this ecological agriculture of Li Zhao just that? Of course not, I think everyone has also noticed the fertilizer, the final production of vermicompost is the best fertilizer, if the scale is up, then because of the vermicompost, it is very likely to increase the grain production of a layer. Therefore, if ecological agriculture is well utilized, then every link is a treasure.

When I arrived at the Ministry of Agriculture, I told the Ministry of Agriculture where I could still sit still, and soon made a report together with the Ministry of Machinery, and invited experts in agriculture and biology to conduct field investigations with Li Zhao. After learning that Li Zhao had an interview in the afternoon, he said that the Ministry of Agriculture would fully cooperate with the Ministry of Machinery to do a good job in the all-round coverage of this interview. Saying that, they also contacted the newspaper to make the matter clear, and the specifications of this interview have been raised again, and Li Zhao will obviously be the well-deserved protagonist of this interview.
