After studying here for a while, she realized how risky what she was doing, which was purely a blind cat crashing into a dead mouse.

The previous year's weather conditions were good, the water and heat were favorable, the homemade fertilizer stimulated the potential of the land, and there were fewer pests and diseases, so the grain production increased significantly.

But not necessarily this year.

The fertility of the soil is fixed for a period of time, and if the grain is absorbed in the previous year, and the fertility of the soil is not increased this year, and there is no fallow rotation policy, the soil will not rest, and the crop yield will be greatly reduced.

She wanted to seek guidance from experts from the Institute of Agricultural Sciences, so that she could learn how to test the content of trace elements in the soil and how to make compound fertilizer.

If she learns these things, she will no longer be an insignificant junior in the agricultural science department.

You can also rely on what you have learned to ensure the stability of food production in Hongxing Village.

After listening to her thoughts, Professor Li also attached great importance to it, after all, Hongxing Village was the key to his rescue, and if the grain production was only brilliant for one year, all the people would have to pay a serious price.

Maybe he'll be assigned a farm.

His apprentice is very good in his opinion, he has courage, perseverance and intelligence, and the experts who study compound fertilizer are very busy, so he takes the time to teach his apprentice, and he will have an extra helper when he has miscellaneous matters in the future.

Moreover, Professor Li is very reluctant to ask others to help measure soil fertility.

It seems that he is very unlevel.

Peers are light, and it has always been so.

Professor Li took two bottles of wine with him during the meal and took Zhou Xiyue to visit the experts who studied compound fertilizers.

Experts are very talkative, but if Zhou Xiyue is too stupid to meet the standard, don't blame them for not teaching.

Research is at a critical juncture, and there is no time to re-teach someone who has not yet gone to college.

Professor Li glanced at Zhou Xiyue in embarrassment, he felt that his apprentice was good anywhere, but maybe he was a doer, let her farm the land, she would farm, but she didn't know the theory.

Zhou Xiyue saw the expressions of the two people clearly, and the experts who studied compound fertilizer had a good look on their faces, and they didn't believe that this girl would be able to catch up in a short time.

Generally, master's students can get the knock on the door of this agricultural science institute, high school students, isn't this a joke, can she understand the usual professional terms?

Zhou Xiyue is determined to learn, the day of winter wheat planting is not far away, if she can't solve the problem, maybe her future will be ruined, so how can she realize her own value?

She promised on the spot that she would work hard to learn, and if she didn't work, she would automatically quit the Institute of Agricultural Sciences and go back to the Workers, Peasants and Soldiers University to learn from scratch.

Expert Liu immediately smiled: "The quota of the Workers, Peasants and Soldiers University that others can't ask for, you still can't look down on you?" ”

Zhou Xiyue smiled very sweetly: "Compared with what we have learned in this agricultural science, what we have learned in the University of Workers, Peasants and Soldiers is of course nothing." You don't even bother to let me go for progress? ”

"It's sharp and quick-witted. I hope you will use this wisdom to study. ”

Zhou Xiyue immediately saluted the two teachers and said loudly: "Guarantee to complete the task." ”

The young man is very energetic, with two braids, bright eyes, and a vigorous and never-admitting strength, which looks like a small aspen that has just sprouted tender leaves in spring.

It's refreshing to watch.

Professor Li nodded in admiration and pride, and said to Professor Liu, "My student is still young, you have to teach carefully." ”

Looking at Zhou Xiyue's eyes full of curiosity, Professor Liu looked at him and said softly: "That's nature. ”

Zhou Xiyue's eyes narrowed and she smiled: "Teacher Liu, you can call me in the future." ”

Professor Li's tone was sour: "Oh, I only see the newcomer laughing, but I don't see the old person crying, Xiao Zhou, you are really excessive, and you have never been so attentive in front of me." Lao Liu is so good? ”

Zhou Xiyue knew that Professor Li was not really angry, so she smiled and said, "Of course, you and Teacher Liu are the treasures of the country, and I can't be too respectful." ”

The two professors laughed and said that she had honey on her mouth.

Since you have to study, the next few days will not be easy.

Professor Liu brought her a stack of valuable materials.

These materials are the result of painstaking research by experts, and for various reasons they are not available.

In other words, if you leave the Institute of Agricultural Sciences, it is impossible for you to see these materials.

Zhou Xiyue immediately began to study hungrily.

These materials are detailed information on fertilization of winter wheat.

The amount of fertilizer that was familiar to later generations of farmers was only known to a few experts at this time.

40 to 50 kg of fertilization per acre in high-yield fields and 30 to 40 kg in medium- and low-yield fields.

In arid plots, fertilizer is applied deep under the plough and then covered with soil. In clay wet areas, spread fertilizer on the ground and turn over the soil. Fertilizer is better when used with farmhouse fertilizer.

The next step is to top dressing late wheat and wheat with insufficient bottom fertilizer.

The application of high-nitrogen compound fertilizer at the jointing stage and booting stage of wheat can promote the thickness of wheat rhizomes, increase the number of grains per panicle, and improve the lodging resistance of wheat. It can also increase the weight of wheat grains and achieve the purpose of effectively increasing yield.

Zhou Xiyue benefited a lot after reading it, and what she learned before was compared with these, which was the difference between slash-and-burn farming and intensive farming.

The land in Hongxing Village is still not finely planted.

The data also mentions the consequences of excessive use of elemental fertilizers and compound fertilizers, such as soil compaction, reduced crop yields, and pollution of environmental water sources.

Compared with the agricultural development of the previous worlds and the 21st century, it can be said that the prediction is very accurate.

In later generations, there was no shortage of fertilizer, but the utilization rate of fertilizer was still insufficient.

Perhaps it is because the popularization of science is not in place, and the sowing of fertilizer in rural areas is simply sprinkled next to the roots of crops, and the quantity is not strictly controlled, and there is often a situation of "burning seedlings".

Zhou Xiyue's eyes lit up, and she saw a broad prospect.

Agricultural cooperativeization is not conducive to the increase of grain output in the short term when the means of production are insufficient.

Seeds have such great potential, even if all the efforts are put on the land, how many catties can the grain output increase throughout the year?

There is no heavy sweat to pay for this.

However, in the long run, with the emergence of high-quality varieties, the popularization of compound fertilizers, and the development of agricultural mechanization. Large-scale farming is the only way to maximize the economic benefits of agriculture.

Experts continue to study day and night, but there are still many problems that need to be solved urgently.

If she can contribute in this regard, she will have no regrets in this life.

Zhou Xiyue, who has found her life purpose, is like a sponge, hungry for knowledge.

Professor Liu saw that Zhou Xiyue wanted to return the information every three to five days, and he was worried that she only wanted speed rather than quality, and if she did not lay a good foundation for biological knowledge, it would be difficult to understand it in the future.

took the materials she read for the exam on the spot, but I didn't expect Zhou Xiyue to give him a big surprise, although it is not to the point of not forgetting, but the knowledge that should be known is understood very clearly, and he can draw inferences from one another.

Professor Liu was very satisfied, so he gave her more study tasks, and Zhou Xiyue was very happy.
