Chapter 1657: Self-reliance and adequate food and clothing
Agriculture books are actually not complicated, but they are a bit convoluted. The units used in the books are often different from those in the instructions for pesticides and fertilizers. For those with low knowledge, such as Tu Liangzhi, It's a bit confusing for people to understand.
For example, the book says that chlorine is one of the trace elements needed for normal crop growth, but potatoes are one of the crops that least need chlorine and are taboo about chlorine. The soil contains too much chlorine. , will interfere with the synthesis and transportation of potato starch, significantly reducing the taste and yield of potatoes.
Secondly, chlorine will also acidify the soil, which will directly affect the development of potato root systems and the activity of beneficial microorganisms, leading to aggravation of potato soil infectious diseases, root rot, and even root necrosis.
So when planting potatoes, you must avoid using chlorinated fertilizers such as potassium chloride, calcium chloride, and ammonium chloride. You can choose to use nitro or urea-based compound fertilizers to promote the growth of potatoes.
But now Tu Liangzhi only has potassium dihydrogen phosphate distributed with the help of his superiors. Comrade Tu Liangzhi wants to scold his mother. Can this be used? !
Zhou Zhi knew that of course it can be used, but it needs to be used during the critical period of potato growth.
Generally speaking, crops require a large amount of nitrogen fertilizer from sowing to the emergence stage, and a small amount of phosphorus fertilizer can also be applied. During the flowering stage, phosphorus and potassium fertilizers need to be applied. As the crop enters the middle and late stages of growth, the demand for nitrogen fertilizer The demand gradually decreased, while the demand for phosphorus and potassium fertilizers, which play an important role in promoting the formation, expansion and quality improvement of underground tubers, increased significantly.
This principle is suitable for sweet potatoes. Potatoes are also tubers, so they are equally suitable.
Of course, the cheapest and most practical one is organic base fertilizer. The Yi people raise cattle and sheep, and cow dung is used as fuel, so sheep dung is useless.
If this thing is not used properly, the seedlings will be burned. They must be collected together first and fermented and matured before they can be used.
The remaining step is to burn the mountains, and you can get a lot of plant ash, but the fertilizer effect of the plant ash is not good, and on the windy days that are often here, it is a trivial matter for you to blow the plant ash, causing For forest fires, even sitting in jail is not enough to compensate.
Concerning the preparation of pesticides and the dilution of pesticides mentioned in agricultural technology books, Tu Liangzhi also felt paralyzed.
The concentration of drugs mentioned in agricultural machinery books is often different from the actual concentration of pesticides. There is a conversion process;
What is mentioned in the book may be mass concentration, while what is mentioned in the drug instructions is may be the molar concentration, and there is a conversion process here.
These are also places that put Tu Liangzhi in a difficult position.
Fortunately, the principles of these things are not too complicated. Tu Liangzhi, who has been a soldier for more than ten years, is not lacking in mathematical foundations. What is lacking are chemical concepts and appropriate explanations.
After Zhou Zhi explained the truth to him clearly, and then gave him two more questions to prove that he really knew it, Tu Liangzhi slapped his forehead: "Isn't this difficult? I think it's just knowledge. People deliberately make some twists and turns, specifically to embarrass us farmers!”
"We can't blame the learned people for this, we can only blame the agricultural technology station for not coming to the countryside." Zhou Zhi said: "It takes more than six hours to drive your own car from the county. If permanent personnel are sent, it is estimated that the county finance will also be Can’t afford it.”
“What should we do?”
"Self-reliance, adequate food and clothing." Zhou Zhi, however, did not care much about the difficulty of the current situation, and directly used the famous eight words of the great man: "Unite all the forces that can be united, and let the strongest one stand firmly on our side. Come.”
< br>"Is this why you went out for a walk with Atta early in the morning?"
"Uncle Tu, you are wrong, grandpa is much more transparent than you." Zhou Zhi smiled and said: "He took the initiative to greet me , took me out for a walk.”
“Then. It was you who persuaded him yesterday. He wanted to steal someone from me!" Speaking of this, Tu Liangzhi seemed to be angry again: "It's not like he's never done it before!"
"I don't think so! I am so important." Zhou Zhi couldn't help laughing: "In addition to doing the project, The rest of the time is for you to work together, I have no objection." Tu Liangzhi was not very satisfied with Zhou Zhi's statement: "Why don't you work on the project together with him? It’s on!”
"But that is my essential job and the purpose of coming here." Zhou Zhi is not afraid to tease Tu Liangzhi. Sometimes he feels that it is appropriate to help the old man to make this guy angry: "You can't You’re putting the cart before the horse!”
While the two were arguing in the agricultural supplies warehouse, , but Wu Renzhong came running: "A big car came at the door. It said it was looking for Mr. Zhou. I think it can only be your thing."
"Is it from Blue Sky Electric?"< br>
“Yes, yes, Blue Sky Electricity, a fat white man said it was Hao Gong.”
"That's it." Zhou Zhi waved his hands and said happily: "I don't have to worry about running out of power 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 Electric Power , he could not have imagined why a poverty-stricken rural grain station in a national-level poverty-stricken county would issue an order to install a set of titanium dioxide dye-sensitized commercial thin-film solar cells that are currently at the world's leading level.
There is also a matching energy storage UPS computer room.
This row of mud houses does not look like it meets the minimum standards for UPS computer room installation.
When we first received the order from the business representative, everyone speculated for a while, and finally thought of the satellite launch center in the autonomous prefecture.
Such advanced solar power generation equipment may only be the demand there, and it has something to do with high technology.
But if this grain station were that kind of unit now, the confidentiality and disguise work would be done extremely well. The old Yi man with dark skin and wrinkles on his face at the door, holding an orchid pipe, was dressed in ethnic style. And dressing up, foreigners can't look that way no matter what.
And the dog next to him, pouting, revealing two small white teeth like thin nails at the top and bottom, staring at him with its upside-down triangular eyes, as if looking at a plate Food is the same.
"Behave, Black Dragon! This is a guest!" Zhou Zhi hurriedly greeted: "Hao Gong, right? Your blue sky power moves are really good. This speed is really worth learning from our four-leaf clover."
"Where is it..." Hao Chunwang finally came to his senses and asked his colleagues to unload the truck: "We are all incubated companies from brother universities. Clover's growth experience is an example for us to learn from!"
"Let's not flatter each other first." Zhou Zhi smiled and said: "Let me introduce it to everyone..."
As soon as Wu Renzhong came to call for help, the children could no longer attend class and all ran out to watch. lively.
Not only the children, but also other people in the village gathered around and commented on the big blue truck.
"How about everyone help me?" Hao Chunwang asked tentatively: "This battery is quite heavy. We still need to see where the power distribution room and UPS computer room are located... "
Lao Chiri waved his hand and muttered something in Yi, and the people around him, men, women, old and young, all came up together: "Let's unload, let's do it..."
