As the saying goes, what kind of master there is, what kind of subordinates there are.

Zhao Yu is dedicated to the country, and Qi Bokun, the official secretary who is deeply worried about this Great Song Dynasty together with Zhao Yu, is also such a person. Therefore, since Zhao Mei ascended the throne, they discussed the officials who were promoted or supported by various means, all of whom were upright and dedicated to the public.

This is the case with Wu Shangshu.

If it were someone else, he might have been thinking about getting a piece of the pie from the huge credit of double cropping rice, and no matter how bad it was, he would have to draw Du Jinning into his own camp and use it for his own use.

Wu Shangshu didn't think so. Excited about such a yield, he thought about how to give Du Jinning credit, so that she could create a more brilliant future for the Great Song Dynasty.

Du Jinning was not very satisfied with such a yield per mu.

You must know that in 1958, before the emergence of hybrid rice, the average annual yield per mu in the country was about 400 kilograms. Since 1976, hybrid rice has been popularized in a large area across the country, and the average yield per mu has increased by about 20% compared with conventional rice. In 2000, the first phase of super hybrid rice presided over by Yuan Longping yielded 700 kg per mu; In 2004, the second phase yielded 800 kg per mu. By 2017, when she crossed over, it was no problem to plant two seasons a year, and generally produce one ton of grain per mu under better soil and gas conditions. Of course, this refers to the yield per mu of a season of late rice.

According to the conversion of one stone in the Song Dynasty equivalent to the modern ninety-seven kilograms, after her careful guidance and Song Zhuangtou's careful care of the high-quality fields, the highest yield per mu is only less than 400 kilograms, which also has a bonus of 10% per mu for rice and fish farming, otherwise it will be less.

Such a yield per mu is far lower than her psychological expectations.

The problem is with fertilizers and pesticides.

Although later generations do not have a good impression of chemical fertilizers and pesticides, they always feel that green food without chemical fertilizers and pesticides is the healthiest. However, it is undeniable that chemical fertilizers and pesticides are a powerful guarantee for agricultural planting to increase production and income.

Because no matter how fertile the field is, it cannot withstand the demand for plants every year and two seasons, and it will be reduced to barren land after a few years of planting; In addition, the macronutrients nitrogen, phosphorus and potassium in the soil usually cannot meet the needs of crop growth, and chemical fertilizers containing nitrogen, phosphorus and potassium need to be applied to make up for it.

At the same time, once the grain in the field is sick or has an insect infestation, basically the field will not produce anything, and the year's hard work will be wiped out, and the farmers will fall into a vicious circle of poverty.

In her previous life, although Du Jinning had the ability to never forget, if she was interested, she could remember how to make tofu, and she was involved in tea planting and production, garden planting and design related to her profession, but she was not a chemist and physicist. Although she was given the time to make fertilizers and pesticides with the chemistry and physics she learned in high school and college, it was a long-term process.

Putting aside her relationship with Qi Muyuan, the great crime of disguising herself as a man is like a knife hanging above her head and falling at any time, making it impossible for her to do this work that takes several years or even more than ten years with peace of mind.

Forgive her for being selfish, she did not have the consciousness to shed her blood for the ancient people and to sacrifice her life and her mother's life for them at any time.

Studying hybrid rice is the limit of what she can do.

However, this did not prevent her from giving the officials of the Ministry of Industry a direction of research.

She frowned and said to Wu Shangshu: "I think the yield per mu can be increased a little more, if the fertilizer is applied properly." ”

Her expression of dissatisfaction with the result was very stimulating to Wu Shangshu.

With such a yield per mu, Du Jinning is still not satisfied? At this time, he is not complacent, but thinking about how to increase production?

Wu Shangshu only felt that he had been deeply shocked and baptized by indescribable impact and baptism in his heart.

He hurriedly gathered his mind and asked, "Why did Lord Du say this?" But what's the experience? ”

Du Jinning nodded: "According to my many years of experience in planting species and flowers, I found that different plants have different needs for fertilizer; And it needs different fertilizers at different times of growth. If we can study this law and apply fertilizer in a targeted manner, grain output will inevitably increase by a large margin. ”

She looked at Wu Shangshu and said very earnestly: "Wu Shangshu, this is a major event that will benefit the present and the future, can you set up a special department in the Ministry of Industry and recruit a few talented people in this area to do this?" I have limited energy alone, and I take up all my time studying rice seeds, and I don't have the skills. ”

Although this matter can only be decided after reporting to Zhao Yu, Wu Shangshu still gave Du Jinning a positive answer: "It's no problem to set up a department, and it's no problem to recruit a few people." But now that you have such an idea, can you take them along and show them the way? ”

"That's fine."

Even if Wu Shangshu doesn't say it, when the time comes for the establishment of the institution, she will still put forward this point. After all, with her as a guide, those people can avoid a lot of detours. A project that takes tens or hundreds of years to bear fruit, under her guidance, may be able to achieve results in a few years.

Wu Shangshu looked at her, and asked tentatively, "Let them come here and bring it to you?" ”

For fear that Du Jinning would refuse, he hurriedly added: "It doesn't take up your time, you just need to tell them what to do, let them do it, you don't need to do it yourself." ”

If Du Jinning was a man and determined to do this, he would naturally not refuse Wu Shangshu's proposal.

But she has too many secrets on her, and she doesn't want too many people to gather around her - although Lu Jiuyuan and they are also here, as long as she says it is inconvenient to disturb, they will definitely not come to disturb her. And they have been together for many years, and they can trust each other's character.

But those court officials are different, they are all older than her, they have deep qualifications, and one or two of them are uncles. Besides, who knows if there are some people with evil intentions among them?

She immediately shook her head and said, "It doesn't have to be. They were all officials of the Ministry of Works, and they were proficient in agricultural affairs; I know the same thing in Runzhou, how can I guide them? When you set up a department, you don't have to put my name in it, I really don't have much energy to do anything else. If they research the results, I don't contribute much, and it's not good to bypass me when I talk about the ICBC reward, and then it will make the emperor embarrassed, don't you say? So it's better that I didn't join the team in the first place. ”

She smiled: "Wu Shangshu, don't worry, I also hope that they can research good fertilizers to make my mu production capacity go further." I only hope that our Da Song is good, what do I know, what do I think, and I will not hide my secrets. ”

Du Jinning said this, and Wu Shangshu reacted.

He nodded and said, "You're right, but I didn't think it through." ”

Although he will carefully consider the candidates when he sends people to do fertilizer research, those officials who just beep but don't do anything don't want to. But if there is a situation like Du Jinning, it is not easy for him to deal with it.

"Okay, then do as you say." He said.
