For Li Zhao, this situation is not a burden, it can be regarded as a little warm trouble, but he is also quite tired every day now, and he still needs to work overtime to draw pictures for a period of time at night, which is still quite tiring for him. Of course, it doesn't take him long to take care of the children, that is, just after getting off work, and if Father Li or Father Su doesn't work overtime, they will come over to sit for a while, they prefer to take care of the children than Li Zhao.

Soon after eating, Li Zhao's house was also lively again, the first to come over was Lou Xiao'e, she came with her child, this is also a routine, her status at home is high and boundless, basically cooking or something is He Yuzhu's job, after eating, basically she brought the child to chat with Su Ya.

Seeing this situation, Li Zhaoyou stared at the children doing their homework for a while, and then went upstairs to start busy with his own affairs. It's just that the time didn't last long, Father Li and Father Su came to Li Zhao's office with a meal, and they came over like this today, obviously there was something, otherwise they wouldn't have come to him in such a hurry, and looking at this situation, it is estimated that they went to the farm, and rushed back directly without eating dinner, which is quite rare.

When Li Zhao saw this situation, he hurriedly cleaned up the table, asked them to put down the things in their hands, and then moved the stool or something, and when the two of them sat down, Father Su said directly: "The Agricultural Research Institute has done a good job in the planning of the farm, I went with your father today to review it, do you want to go and see it too?"

This should be considered a good thing, it took more than a month, and now it is completed, it seems that the preparation should be very sufficient, after all, with the experience of the current Agricultural Research Institute, it is impossible to complete the program of the two farms for such a long time, but it has not been completed until now, and it is obviously a great effort.

However, Li Zhao was still puzzled, so he asked, "Why did it take so long, I thought that the farm had already started construction, with their speed last year, not to mention now, at least ten or eight farms can be completed, right?" It's only been done now, what kind of plan have they come up with?"

Li Zhao is indeed puzzled, although the idea was proposed by Li's father at that time, but the specific aspects were added by Li Zhao, so Li Zhao is still very puzzled about what the project has become now, after all, this investment is very large.

At this time, Su's father said, "If there is a problem, it can be regarded as a problem, and the biggest problem is that the cost is too large, didn't you give a multi-layer three-dimensional planting model? I feel that they have changed a little too much now, and I feel a little unreliable, and the other is the height of the greenhouse, which they set to about eight meters, and the cost is not low."

Li Zhao also nodded when he heard this, it is indeed not low, you must know that the general greenhouse is already very high at four or five meters, and now it is directly made to a height of eight meters, what is this going to plant? It's a bit too high, although he wants to engage in three-dimensional planting and arrange a few more layers of crops, but there should be about four or five meters, so that he can plant three meters.

After all, no matter how high it is, the operation will be very difficult, and the demand for equipment will be much higher, after all, if the dish grows to six or seven meters high, picking is also a big problem, it is impossible to directly install multi-layer shelves, right? That would not be very convenient, so Li Zhao was also quite puzzled about this eight-meter height.

Li Zhao asked at this time, "Did they bring back their specific plan?" I'll see what the situation is, I also feel that this height is very abnormal, if the crop species are really that high, then our management costs will be ridiculously high, and then the gains may outweigh the losses, and the amount of investment will be much higher."

After listening to Li Zhao's words, Father Su said, "The specific plan will be handed over tomorrow, and it is too late to discuss it today, but I can tell you about the plan roughly." Then Father Su and Father Li introduced the plan given by the Agricultural Research Institute while eating, and the two also complemented each other, and soon explained the general content.

How to say it, in Li Zhao's feeling, it is too radical, yes, it is really too radical, Li Zhao's plan is to add a fish farming, almost make it look like about four to five layers, after all, the demand for sunlight for fish farming is not large, the upper layer is planted with mushrooms and the like, which is considered to provide carbon dioxide for the greenhouse, and then there are two or three layers of crops on top In this case, all the crops can be taken within three meters

Finished planting.

However, what surprised Li Zhao was that they actually added other things, such as bean sprouts, leeks and other crop layers, which could be regarded as adding two to three layers of planting area, and in order to better manage the upper crops, it was really as Li Zhao thought, to directly engage in the air shelf, in this case, they would directly expand the planting scale of about four layers that Li Zhao envisioned to seven to eight layers, but this was not necessary at all.

Let's just say that bean sprouts, put here is basically a rigid set, belongs to the increase in order to increase the number of layers, such an addition, is not necessary at all, because the mushroom planting layer, itself can also be used to sprout bean sprouts, when the time is needed to arrange it, there is no need to engage in such a high greenhouse.

It's just that Li Zhao doesn't know why there is such a stupid trick, you must know that the professionalism of the Agricultural Research Institute is still very high, and there should be no such situation, what else is there Li Zhao doesn't know?

After hearing this, Li Zhao couldn't help but ask, "The Agricultural Research Institute shouldn't have made such a stupid move, right? Is there anything wrong in between? I don't think this idea was a layman's idea, a bit of a high-end idea for the sake of being high-end."

After listening to Li Zhao's words, Father Su said at this time: "We just don't know what's going on, that's why we have this doubt, we thought it was instructed by you, and we were going to dig a hole for others, but it doesn't seem to be."

Li Zhao was also stunned when he heard this, he was willing to dig a pit for others, but it cost hundreds of millions more to dig a pit, Li Zhao couldn't do it, but he didn't know who came up with this, it was obviously very unreasonable. After all, many facilities in this era cannot be compared with the future, and many things can be handed over to machines in the future, but this era must be done manually, in this case, it is obvious that high-altitude planting is not appropriate.

Li Zhao also said at this time: "The suggestion I gave at that time was to add a layer of fish farming, and it would be almost enough to make four or five layers, and I was still going to let them try to breed fungi in one layer, and I didn't think about making so many layers."

Li Zhao has actually never seen real three-dimensional planting, but no matter how he has never seen it, he can understand that it is unreliable to make seven or eight upper ten layers of planting, after all, after reaching the lower layer, the sunlight will basically be blocked, and the lower crops, photosynthesis is definitely relatively poor, and Li Zhao is obviously not ready to make up the light now, the current electricity bill is too expensive, and it is not cost-effective to make up the light at all, you can try it in the future, but it is not possible now.

You must know that the electricity bill in this era is two cents per kilowatt-hour, and this price is about equivalent to ten yuan per kilowatt-hour sixty years later. The best way is natural light, and the cost of supplementing light is simply unbearable in this era, but thinking of this, Li Zhao suddenly asked, "Won't they be preparing to take artificial supplemental light measures?" I didn't hear you mention this just now."

Hearing Li Zhao talk about artificial lighting, Li's father said, "There seems to be such a thing, they are talking about using scientific and technological means to imitate the growing conditions of crops and achieve the conditions of 24-hour uninterrupted growth."

Li Zhao heard it, good guy, the case has been solved, it turns out that this is the case, they really came up with something high, it must be unrealistic to do so at this time, after all, the electricity bill in this era is too expensive and inappropriate.

Li Zhao also gave a general explanation of the situation at this time, and then said: "This plan is not good, at least it is impossible to achieve it in a short period of time, we are still in a state of lack of electricity, if we make up the light, we need at least one or twenty kilowatt-hours of electricity per acre of land every day, in this case, it will cost six or seven thousand kilowatt-hours of electricity a year, and the electricity bill alone will cost more than a thousand, what kind of money do we make, who came up with this plan?"

Li Zhao was also tired, thinking that there would be no problems, so he didn't care about it, but he didn't expect that the Agricultural Research Institute was so good at playing now, and was already directly ready to start a comprehensive manual intervention in crop growth, but they were a little too hasty this time, and the current national strength was not suitable for such a thing at all. As far as the current situation is concerned, there is no possibility of implementation in at least twenty or thirty years, and it can be tried in forty or fifty years.

The reason is also very simple, one is that the agricultural products of this era are too cheap, take all kinds of green vegetables as an example, which are more scarce, such as seasonal edamame, which is more expensive, after all, the yield is low.

But it's just a dime a little more than a catty, and the normal greens are basically less than five cents per catty, in this case, if you want to protect the capital, then the greens per mu of land must be more than 30,000 catties to protect the capital, is it necessary to plant?

Of course, there are fish and some other outputs, but if you don't use supplemental light, then you can basically earn at least a few hundred per acre of land, if so, it is very likely that you can earn more than a thousand, and you can invest hundreds of millions less, in this case, there is no need to make it so complicated, and the current plan is definitely worth the loss.
