Riding the wind of rebirth

Chapter 1657: Self-reliance and Prosperity

Agricultural books are actually not complicated, just a bit confusing. Also, the units used in the books are often different from those on the instructions for pesticides and fertilizers, which makes it a bit confusing for people like Tu Liangzhi who have a low level of knowledge.

For example, the book says that chlorine is one of the trace elements required for the normal growth of crops, but potatoes are one of the crops that least needs chlorine and is most afraid of chlorine. Too much chlorine in the soil will interfere with the synthesis and transportation of potato starch, significantly reducing the taste and yield of potatoes.

Secondly, chlorine will acidify the soil, which will directly affect the development of potato roots and the activity of beneficial microorganisms, thereby aggravating potato soil infectious diseases, root rot, and even root necrosis.

Therefore, when planting potatoes, be sure to avoid using chlorinated fertilizers containing potassium chloride, calcium chloride, ammonium chloride, etc. You can choose to use nitro or urea-based compound fertilizers to promote the growth of potatoes.

  Now Tu Liangzhi only has potassium dihydrogen phosphate distributed by the higher authorities. Comrade Tu Liangzhi wants to curse, can this be used? !

Zhou Zhi knew that it could of course be used, but it needed to be used during the critical period of potato growth.

Generally speaking, crops require a large amount of nitrogen fertilizer from sowing to seedling emergence, and a small amount of phosphorus fertilizer can also be applied. During the flowering period, phosphorus and potassium fertilizers need to be applied. As the crops enter the middle and late stages of growth, the demand for nitrogen fertilizers gradually decreases, while the demand for phosphorus and potassium fertilizers increases significantly. Phosphorus and potassium fertilizers play an important role in promoting the formation, enlargement and quality improvement of underground tubers.

This principle applies to sweet potatoes, and the same principle applies to potatoes, which are also tubers.

Of course, the cheapest and most suitable fertilizer is organic base fertilizer. The Yi people raise cattle and sheep, and use cow dung as fuel, but sheep dung is of no use.

If this thing is not used properly, the seedlings will be burned. They must be collected together and fermented and matured before they can be used.

The remaining option is to burn the mountains, which can produce a lot of wood ash. However, the fertilizer effect of wood ash is not long-lasting, and when there are strong winds as is common here, it is a small matter to have the ash blown away. However, if it causes a forest fire, the compensation would be even more serious than a life in prison.

Tu Liangzhi was also confused about the preparation of pesticides and the dilution of drugs described in agricultural technology books.

The drug concentrations mentioned in agricultural machinery books are often different from the actual concentrations on pesticides. There is a conversion process here;

What is mentioned in the book may be mass concentration, and what is mentioned in the drug instructions may be molar concentration. There is a conversion process here.

These are also the things that make Tu Liangzhi feel embarrassed.

Fortunately, the principles of these things are not too complicated. Tu Liangzhi, who has served in the army for more than ten years, is not lacking in mathematical foundations. What he lacks is chemical concepts and appropriate explanations.

After Zhou Zhi explained the principle to him clearly and gave him two questions to prove that he really knew it, Tu Liangzhi slapped his forehead and said, "This isn't that difficult! I think the scholars are deliberately making things difficult to embarrass us farmers!"

"We can't blame the scholars for this, we can only blame the fact that the agricultural technology station didn't go to the township." Zhou Zhi said: "It takes more than six hours to drive from the county. If we send permanent staff, I guess the county finances can't afford it."

"Then what should we do?"

"Be self-reliant and have enough food and clothing." Zhou Zhi did not care much about the difficulty of the current situation, and directly threw out the eight famous words of the great man: "Unite all the forces that can be united, and let the strongest force stand firmly on our side."

"Is this why you went out for a walk with Ata so early in the morning?"

"Uncle Tu, you are wrong. Grandpa is much more insightful than you." Zhou Zhi smiled and said, "He took the initiative to greet me and took me out for a walk."

"You persuaded him yesterday. He wanted to snatch my girl away!" Tu Liangzhi seemed to get angry again when he talked about this: "It's not like he hasn't done it before!"

"I don't think I'm that important." Zhou Zhi couldn't help laughing: "Apart from working on the project, the rest of the time is for you to use together. I have no objection." Tu Liangzhi was not very satisfied with Zhou Zhi's statement: "You work on the project, but you work with him? It's obvious that you are still sitting on a crooked bench!"

"But that's my essential job, and it's also the reason why I'm here." Zhou Zhi wasn't afraid to tease Tu Liangzhi, and sometimes he felt that it was his duty to help the old man to annoy him: "We can't put the cart before the horse!"

While the two were arguing in the agricultural supply warehouse, Wu Renzhong came running over and said, "There's a big truck at the door, and they said they're looking for Mr. Zhou. I think it can only be your stuff, Elbow."

"Is it from Blue Sky Electric?"

"Yes, yes, yes, Blue Sky Power. A fat white man said he was Engineer Hao."

"That's it." Zhou Zhi waved his hands and said happily, "We don't have to worry about running out of electricity this time!"

Hao Chunwang stood at the door of Lianhe Township Grain Station with a confused look on his face. As a senior engineer of Blue Sky Power, he could not imagine why a grain station in a poor township in a national-level poverty-stricken county would place an order to install a set of titanium dioxide dye-sensitized commercial thin-film solar cell arrays that are currently at the world's leading level.

There is also a matching energy storage UPS room.

This row of mud houses doesn't look like they meet the minimum standards for installing a UPS room.

When we first received the order from the business representative, we speculated for a while and finally associated it with the satellite launch center of the autonomous prefecture.

Such advanced solar power generation equipment could only be the product of demand there, since it at least has something to do with high technology.

But if this grain station is that kind of unit, then the confidentiality and disguise work must be done too well. The old Yi man at the door with dark skin, wrinkled face, and an orchid pipe in his mouth, is dressed in ethnic style. Outsiders can never look like him.

And the dog next to him, with its mouth bared, revealing two small white teeth like thin nails on the upper and lower parts, and its upside-down triangular eyes staring at him as if it was looking at a plate of delicious food.

"Black Dragon, be good! We are guests!" Zhou Zhi hurriedly called out, "Engineer Hao, right? You guys at Blue Sky Electric are really good at what they do. Your speed is really worth learning from for us at Cloverleaf."

“No, no…” Hao Chunwang came back to his senses and told his colleagues to unload the truck: “We are all incubated enterprises of sister colleges and universities. Clover’s growth experience is our role model!”

"Let's stop flattering each other." Zhou Zhi said with a smile: "Let me introduce it to everyone..."

As soon as Wu Renzhong came to call people, the kids could no longer attend class and they all ran out to watch the fun.

Not only the kids, but even other people in the village gathered around and commented on the big blue truck.

"How about everyone lend a hand?" Hao Chunwang asked tentatively: "These batteries are quite heavy. We also need to see where to set up the power distribution room and UPS room..."

Old Chi Ri waved his hand and muttered something in Yi language. All the people around him, regardless of age or gender, came up together: "Unloading, right? Let's do it, let's do it..."
