Today is different from the last trip, these people will stay until the evening, and they need to be seen together by these people to see how the lights are made up at night, so that people can know what all the facilities do.

Soon, most of the people had experienced it and began to listen to the explanations of the technicians of the Agricultural Research Institute, and with the explanations, all the crops had been prepared in the first planting place. This is a shelf for planting vegetables, of course the bottom is the pool, the twenty-level pool, put about fifty fish, put so little first, the main thing is to adapt to it first, see if the water can raise fish, don't put a lot of death.

The above vegetables can consume ammonia nitrogen and other inorganic salts in the water, and the water purified by the vegetables can increase the oxygen content of the water body as it flows down the sink and into the pool. Then there are several layers of fungus cultivation layer, the light in these places is relatively weak, more suitable for the growth of fungi, the sunlight and lights that shine in, has been blocked by the upper layer into a slope-like planting trough, it is a good environment for the growth of various fungi.

It's just that these have a height of nearly two meters, after all, the fungus breeding layer needs to be sprayed with water, if there is no gap, then it will lead to difficulty in spraying water, so that there is a gap of about 20 centimeters.

In order to save costs, these shelves for operation can be pushed and walked, and there is no fixed way, but Li Zhao looks at the shelves used for these operations are very unreliable, the height of planting without him is a bit too high, the greenhouse is almost eight meters, and the planting will be about six meters high, and the operation may be very troublesome in the future, Li Zhao feels inappropriate for such an operation.

In this case, the things planted in the upper layer can only be those with relatively small yields, easy to manage, and most importantly not prone to insects, and there is no way to use pesticides here, after all, there are fish raised below.

Seeing this situation, Li Zhao said to Su's father: "I still feel that this greenhouse is too high, it is a bit difficult to operate, and if you use a shelf, it will be more difficult to collect vegetables in the future. In the upper layer, it is better to plant crops that do not yield well and are not prone to insects, otherwise it will be very troublesome in the future, and the gains will outweigh the losses."

At that time, Li Zhao raised this question, and now it looks like this, Su's father said at this time: "The vegetables on the lower layer are relatively easy to handle, and when considering the problem of harvesting vegetables, when designing, I made an article on the pool support frame, which can directly build a springboard on it, and the lower layer of crops can be planted and harvested on the springboard, but the upper layer can only use a shelf, and I think this shelf is indeed very inconvenient."

Li Zhao also sighed a little when he saw it, thinking that everyone had already seen the problem at this time, but it was obvious that he couldn't retreat at this time, but he could remedy it, such as preparing a movable lift, which was also simple, and the greenhouse could be plugged in everywhere, and it could be used for lifting after receiving vegetables.

However, the planting, management, and harvesting of the upper layer are indeed problems, and if you don't want to solve them, there will indeed be a lot of trouble, but Li Zhao doesn't plan to care about the situation of the 100 acres of land, after all, the tens of thousands of acres of land are four-meter-high greenhouses, and after leaving room for growth, people only need to stand on the springboard on the pool, and basically complete the operation, unlike now, if you want to operate, you must use a special shelf.

And the shelf looks quite unreliable, it seems that a special supporting climbing equipment must be manufactured later, otherwise it will be really troublesome in the future, of course, this kind of equipment is not difficult, you can use mobile, you can also use guide rails, but this is another expense, this hundred acres Li Zhao feels that it will be at least hundreds of thousands.

One hundred acres of land is not small, there are still a lot of types of vegetables planted here, where green vegetables are planted, there are more fungus breeding trays, and places where tomatoes and eggplants are planted, it is different, these crops will grow relatively tall, so these places only raise a layer of fungi, and the number of layers planted has been reduced to four layers, unlike green vegetables, almost forty or fifty centimeters is one layer, and eight layers are prepared.

And each layer is not only planted in one row, such as greens, at least three to four rows are planted, and tomatoes are planted in each tank only in rows, in short, different varieties, the density of planting is very different.

After looking around, everyone also sighed about the future planting model

Although it is obvious that some problems can be seen, it is obvious that everyone can understand it, after all, it is just at the beginning, especially Ambassador Da Mao, it is even more understandable, after all, I have already told them before, we are verifying, and it is normal for something to go wrong.

Obviously, the people in the research institute have also found the problem, Li Zhao saw that they had discussed it with the person in charge of the mechanical institute, thinking that they were trying to find a way to solve it, in fact, these are relatively easy to solve, but they just need to spend some money, no, none of these people are looking for him, obviously they all think that this problem is not difficult.

In this way, everyone stayed here directly for a long time, and when it was almost eleven o'clock, the greenhouse was already hot, and under the command of the technical staff of the institute, the shade net began to be unfolded, these are relatively simple things, but the effect is not small, at this time it has reached July, after the summer, although it has not yet reached the hottest time, but the sun at noon is still a little too sunny, for the new seedlings planted here, a little unfriendly.

After reading here, the technician took everyone to visit the seed belt weaving machine, without this, it will be more troublesome to do such a planting, with this weaving machine, it is very convenient to weave the seeds and paper tape together, and then directly arrange the honeycomb seedlings, and when the seedlings are completed, they can be planted as today.

After reading this machine, everyone sighed that this machine was unusual, which directly simplified the originally very troublesome planting. Then I went to see the nursery room, which gave the best environment for the seeds to germinate, and the water sprayed regularly was also the nutrient solution, which could make the seeds grow more robust after germination.

Soon it was noon, and everyone had a simple hospitality meal at the institute, of course, it tasted good, but the specifications, that is, it was really just a hospitality meal. Since the previous leader said this, the hospitality specifications in the factory have not been exceeded, but most of the chefs have been adjusted by He Yuzhu, and the taste is still good.

The afternoon arrangement began to be boring, it was a report on the future of agriculture, and if you want others to follow up, then the best way is to report on the detailed research situation, only in this way can you bring others to this road, of course, the detailed data is definitely impossible to publish.

In view of this, Li Zhao did not delay any longer, he could spare half a day, it was already very good, he still needed to be busy with his affairs in the afternoon, and when he got home from work in the evening, Su Ya had not come back, she should have followed Su's father to visit the evening activities, not only Su Ya, but Li's father did not come back, Li Zhao saw this, so he had to take the child and let Li's mother cook, and Li Zhao asked, "When will Su Ya come back in the afternoon?"

Mother Li saw Li Zhao asking this, and said, "Before you came back, you just fed the child and left not long ago, what are you busy with today? Why does Xiaoya still have to work overtime, and I think she looks like she's basking in the sun today, where did she go?"

Li Zhao was quite surprised, Li's father didn't tell her, so he said, "Didn't you go anywhere, didn't Dad say that the greenhouse at the Agricultural Research Institute was planting today? There will be a lot of people coming to visit, and most of the leaders of the factory are there."

Mother Li heard Li Zhao's explanation and said, "You said this, it turned out to be today, I didn't pay attention to the date."

Li Zhao said at this time: "I'll go over to see the situation after dinner, and I didn't bother to talk to them about things during the day."

After eating, when it was a little dark, Li Zhao also went to the Agricultural Research Institute, and at this time the lights in the greenhouse had been lit, which could be seen from a distance, and it was particularly eye-catching. This is designed according to the light wave absorbed by plant growth, and plants basically do not absorb yellow light and green light, so only red light and blue light are selected, which can save energy more effectively.

The red light and blue light provided can provide the most effective energy for photosynthesis to plants, here is Li Zhao's reminder, as well as the research results of the Agricultural Research Institute. And this kind of test is also very easy to do, just a comparative test is required, and it is easy to determine which light is most beneficial for plant growth.

Soon Li Zhao arrived at the greenhouse, at this time there were many people in the greenhouse, and at this time there were researchers introducing everyone, and at this time, Da Mao's ambassador was still listening to the researchers' explanations with great interest.

This will Li Zhao is completely convinced, this big

The envoy has already taken the bait, just to see how bold they are, this technology can know that it has great prospects when you look at it, but it is very money-burning, but I don't know how determined they are willing to invest, but for Li Zhao, the bigger the investment, the better.

Seeing Li Zhao coming, Father Su said with a smile: "You are not here in the afternoon, Ambassador Da Mao is very interested in everyone's reports, and he has raised a series of questions in each report, thinking that this matter should be done."
