The craze for registration comes and goes quickly, after all, this matter is only related to some people, and after registering, it is just waiting for news. The deadline given by the factory for registration is September 10th, and the remaining 20 days are the preparation time, and the final decision on how large the event to hold, which has no effect on those who are not married.

The least affected were probably the agricultural personnel, who began to return one after another more than 20 days after the dispatch of agricultural technicians, that is, on April 10. After these people went to the promotion place, they investigated everything in detail about the local situation, and this time the investigation was far more detailed than last year, when the investigation last year, it was only a superficial investigation, and this year is completely different.

After all, there are a lot of personnel this year, although each farm is estimated to expand to 100,000 acres, but each farm is divided into a team of more than 60 people, which can analyze the details of each farm in detail. For example, by analyzing the local soil, hydrology, atmosphere, climate, etc., you can know the most suitable crops for the local area, and you must know that even the crops that have been grown in the local area for a long time are not necessarily suitable for the local area.

To take the simplest example, such as soybeans, although the yield of soybeans is very low, soybeans can be grown in almost everywhere, from the white mountains and black waters outside the customs to the mountains in the south. Although they can be planted, the yield of soybeans is very different, for example, the yield of soybeans per mu can exceed 300 catties in some places, while in some places it can only have more than 200 catties, and even in some places the yield can only reach more than 100 catties.

Soybeans alone may more than double the difference, you must know that soybeans are one of the few crops that do not need fertilizer, and different climates and environments will cause such a huge yield gap, so this is obviously the case with other crops, so this time due to the abundance of manpower, so the whole survey was carried out in great detail. In particular, the study of soil and hydrology, which was not available before, was regarded as first-hand information.

Now, these people are analyzing the most suitable crops for local cultivation based on the data obtained, and finally formulating the most suitable ecological agriculture model for local development based on these crops. Of course, this is also Li Zhao's expectation for the future development of agriculture, after all, in the future, agriculture that exists in the form of large farms has the strength to hire resident agricultural experts.

These on-site agricultural experts can conduct in-depth research according to the local situation, and finally give the most suitable development direction for the local farm, and at the same time carry out the most scientific guidance in all aspects of crop growth, and carry out the most timely monitoring of various breeding, so as to escort the development of the farm, increase production and reduce unnecessary losses. Instead of traveling as an expert in the future, you also need to roll out the red carpet for fear of soiling your shoes.

With the return of these people, when Li Zhao went to the courtyard for dinner, he often heard Li's father say: "These experts are different from farming, we usually plant some dung, plow once, and then sow seeds, weed, watch dry and water, and drain water when flooded, these experts are really different, their first thought is to improve the soil quality, what is this soil, isn't it what it is? They can even change the soil first." ….

In fact, it is not surprising that the increase in the promotion area this year has inevitably allowed these experts to encounter saline-alkali land, such a place, without changing the soil quality, it is difficult to plant crops, and of course we must find a way to solve it.

After Li Zhao heard this, he laughed and said, "This is where to go, now there is no money and material input, if everything is sufficient, they can really play with flowers when they farm." Now they are still using soil to plant, and when we invest enough resources, they can not even use soil, directly use water, and even use fog to cultivate, and in the future, you will be surprised by the topsoil, the topsoil quality is just a routine operation, it depends on whether the return is high or not."

Father Li naturally didn't believe this, and Li Zhao also took action, that is, to engage in soilless cultivation, which he happened to have the conditions, and there was a fish pond in the garden on the roof, so he directly engaged in a fish and vegetable symbiosis project. His project is very simple, but it is not simple, the simple method is simple, that is, directly use iron sheets to make a lot of water tanks, directly on the shelf, and then flow directly back to the fish pond water into the tank.

Then it flows back to the pool, of course, the water tank is not big, it is ten centimeters wide and ten centimeters deep, Li Zhao did not make it very big, but he put four rows on the fish pond, and then made three layers, so that the pool was originally only about forty square meters, and he was stunned to make a 480-meter planting tank. After raising the seedlings, after fixing the vegetable seedlings, Li Zhao found Li's father and asked him to see it once, and then he was out of control and had to go to see it every day.

Not only him, but also the staff of the Agricultural Research Institute, after learning about the aquaponics project from Li's father, they also visited from time to time, after all, they mainly lived in the same building with Li Zhao, and after they knew, they basically regarded this place as an observation point, and they would come to record the growth every day, and often take the water away for laboratory tests to monitor the biochemical characteristics, but aquaponics is indeed a very good model.

For fish farming, in fact, one of the troublesome things is the increase in ammonia and inorganic salts in the water, with aquaponics, these harmful materials to fish can be easily absorbed by vegetables, so as to provide a better living environment for fish, which can reduce the number of water changes, to know that fish is quite fragile a creature, the aquatic environment has changed dramatically, it is very easy to lead to fish death, aquaponics can solve this problem very well.

At the same time, due to the ammonia and inorganic salts provided by fish life, the growth of vegetables can also be accelerated, and at the same time, due to the rich nutrients, the growth of vegetables can be faster and larger, and the yield will be very considerable, which is why these researchers went to Li Zhao's house to observe, and they also carried out experiments on the farm.

Of course, the test they did is different from Li Zhao's here, they are directly erected on the fish pond test device, after all, such as Li Zhao's roof to build a fish pond, the cost is still very high, and directly on the edge of the fish pond, which is equivalent to directly widening the land, and because there is no power pumping device, so basically in addition to the iron sheet, the consumption is very small, of course, the consumption of the iron sheet is also very high, but this era of plastic is too short, can only be like this. ….

Of course, Li Zhao not only engaged in a fish and vegetable symbiosis project, there are still 200 square meters left on the roof of his building, and it is not a waste to be empty, so this year he also received a research project at the Agricultural Research Institute, of course, it is a very simple project, that is, to engage in hybrid experiments, and the object of the experiment is also very simple, that is, corn, it should be said that there is no better hybrid crop than corn, corn male and female flowers are separated, and you only need to cut your head in time.

This is also Li Zhao has not done much breeding experiments, the research institute chose the simplest one for him, and this simple, there are still people to help him take care of it, and people who study aquaponics will help him make test records, although the experiment is nominally done by him, to be honest, he really didn't work much.

Soon the time came on the 15th, and the people who went out to investigate basically returned, and these people were divided into groups and began to study their inspection data, discuss together, and give the most suitable plan for local development. Of course, they still remember Li Zhao's entrustment, that is, due to limited experience in the early stage, they can't directly engage in too many projects, at least one farm is only engaged in three or five things in addition to planting, and it is difficult to manage more.

Of course, if they develop and have good projects, they can also make appropriate increases, but it is obviously better to have less in the early stage. Although you can't put your eggs in one basket, too many projects are bound to make the initial management chaotic, and fewer projects can solve this problem well. In the future, someone has concluded that many enterprises are all over the world, and their decline is often caused by uncontrolled development of side businesses.

Although Li Zhao does not think that the project will fail, but he still hopes that the early promotion can be smoother, after all, there are more projects, which also means that more technical personnel are needed, in the early days, whether it is the 998 factory, or the local farm, there is no ability to send many technical personnel, do not forget, there will be a larger scale of promotion next year, after the implementation of this round of promotion, only a small number of technical personnel will be retained to maintain the operation.

And most of the technical personnel, obviously need to prepare for next year's promotion, but also shoulder the responsibility of training, after all, the scale of next year's promotion is too large, these experts may not have enough energy to do guidance. You must know that the area that an expert is basically responsible for is about 1,000 mu now, and next year it will be 30,000 mu, and the pressure is not ordinary

Lay a good foundation.

During this period of time, it can be regarded as the busiest time for Li's father, he was the earliest to contact ecological agriculture, and he was also the first to promote ecological agriculture, so he has his own understanding of ecological agriculture. Recently, he has been in the research institute every day, and these groups who came back first to study what projects should be developed on each farm, after today's discussion, the first batch of audited reports finally arrived in Li Zhao's hands, and Li Zhao began to read them after getting them.
