So he steered the conversation in that direction.

"There's nothing to do right now. In the past, when there were no pesticides, the villagers planted wheat by sowing more seeds and leaving some for the insects to eat. Now with pesticides, it seems that some seeds are saved, but it is not good for people's health. Zhang Zhiju sighed.

"Teacher Zhang, isn't there perennial wheat, which can grow for several years if you sow it once?" Yan Zixiu asked.

Zhang Zhiju was taken aback: "Xiao Yan, your insight is good." Perennial wheat, perennial rice, these have been studied internationally. However, it is difficult to balance the taste and yield. ”

Perennial crops, in fact, are not only good for mixing pesticides less.

For example, when wheat is harvested once a year, the soil is ploughed, and the nitrogen in the soil is released into the atmosphere, causing climate change. Nitrogen, phosphorus and potassium are the three elements, and anyone who is missing will affect the yield. And among them, nitrogen is the easiest to lose. If it is lost, nitrogen fertilizer should be applied again. When it rains, the soil is not only lost, but also the surface water is polluted.

Perennial wheat, on the other hand, can be harvested continuously for many years if planted once. The first crop is the same as conventional wheat production, and from the second crop onwards, production requires only two production steps: field management and harvesting. Farmers only need to plant once and harvest for several years or more in a row.

It is like a sugar cane and a leek, and it grows and grows, and grows and grows, and grows and grows. The same goes for perennial rice.

"Teacher Zhang, do we also have research in China?"

"Yes. My teacher was working on this topic. Progress has been slow, though. Zhang Zhiju was a little helpless.

"Isn't it very difficult?" Yan Zixiu wanted to ask where he was stuck.

Zhang Zhiju said: "One is that there are too few samples that can be referenced, and foreign technology is blocked against us. One is that manpower is sometimes poor. My teacher said that he sometimes seemed to touch a threshold, but it seemed a little unreal. ”

Yan Zixiu understood that on the one hand, he was stuck in the contact surface that was too narrow, and on the other hand, he was stuck in intelligence.

He looked at Zhang Zhiju again with the Time Regression Technique and the Hope Qi Technique, and found that Zhang Zhiju and his teacher had four or five inches of white light on their heads, and they were affectionate and righteous people, trustworthy.

So he had an idea, took out a cloth bag from his carry-on bag (Xianfu), and took out two packs of Wudao tea (special puzzle tea), and handed it to Zhang Zhiju: "Teacher Zhang, you and I are like-minded, and we both want everyone to be rich and healthy." Inside this cloth bag are some of the relevant results of my teacher's research; These two packs of premium nootropic tea, please also taste them with your teacher. ”

Zhang Zhiju was very surprised, how could such a major scientific research achievement be given away casually? He hesitated, "It's not appropriate, is it?" ”

"Teacher Zhang, I won't tell you. I'm a doppelganger now. The high-end agricultural products developed by my teacher and I have already received orders of more than 100 million US dollars at the Canton Fair in the fall. I can't be busy with any of this right now. And you happen to be studying the field of perennial crops. For people like us, no matter who gets things done, as long as it's beneficial to the people, isn't it the same? Yan Zixiu said sincerely.

"Xiao Yan. Your teacher, I haven't met. But from you, I can feel his heart. As long as it is beneficial to others, why should the credit go to me. I admire such qualities. Zhang Zhiju was very moved and accepted the things, "Okay." No matter how hypocritical I am, I'm sorry for you. ”

He couldn't help but feel his heart fluctuate.

Because of this perennial wheat, there is no need to re-plough the ground, no need to re-sow seeds, protect water and soil, reduce the amount of pesticides and fertilizers, save a lot of artificial and material resources, and effectively use idle fields.

The significance of this for the sustainable development of agriculture is too far-reaching.

Yan Zixiu laughed: "Teacher Zhang, the ancients said that the white head is like new, and the cover is the same." This is probably about you and me. ”

"Haha, that's right. Kiss or not, the road is divided, like-minded is pro. It's you and me, too. Zhang Zhiju said happily.

"Teacher Zhang, I still have something to do. We'll see you later. Yan Zixiu stretched out his hand to say goodbye.

"That's for sure." Zhang Zhiju shook hands with him tightly, and his eyes seemed to be glowing.

……

He did a great thing for the people, and Yan Zixiu was happy in his heart.

Back at the base, he said to Xiao Wu: "The matter of the tree wall, it's connected." It is estimated that it will be there at 5 p.m. ”

The two watched for a while as the golems dug earth and laid pipes.

Obviously, these workers are skilled and hard-working, and they have built a pool to purify sewage in the corner of the base. The purification tank is three thirds in size and has a glass lid.

Xiao Wu looked very satisfied, and felt that the construction team that Lao Yan was looking for was reliable.

"Lao Yan, why don't you send water spirit pears to these workers? I'll see you catch whoever you give to whom. Xiao Wu asked.

"Well, I'll give them a few boxes when I get back." Yan Zixiu felt that there would be loopholes from time to time.

At half past four, three more trucks came, pulling two truckloads full of saplings and one truckload of workers, and came to the base with a bang, and twenty or thirty people came down from the cars.

Yan Zixiu and Xiao Wu stepped forward to greet them.

"Hello, are you the boss Kui introduced by my teacher? I'm Yan Zixiu. Yan Zixiu shook hands with Spirit Puppet No. 2, "This is Section Chief Wu." ”

"Section Chief Yan, Section Chief Wu, hello."

"Hello Boss Kui, your efficiency is really high." Xiao Wu shook hands with Spirit Puppet No. 2.

"Section Chief Yan's teacher attaches great importance to this matter, so we hurried here." Spirit Puppet No. 2's acting skills are not low.

"Good. Let's get back to that. If you look at this base, 200 acres of land, the circumference is about 1,400 meters. It takes about 700 trees to plant one tree for two meters. These few places leave space, and later there is the entrance and exit. Yan Zixiu pointed to it.

"Don't worry, two section chiefs." Spirit Puppet No. 2 led the workers to work.

They took shovels and carried saplings to the edge of the field, and they skillfully dug the pits, erected the trees, and filled the holes. One spirit golem planted more than twenty trees. In less than an hour, it was over.

The sapling of the Ruyi Spirit Tree is three feet high. One is inconspicuous, but more is beautiful.

Looking at this circle of three-foot-tall and verdant Ruyi Spirit Tree, Yan Zixiu had a sense of accomplishment, and Xiao Wu was also very satisfied when he looked at it.

I feel that the base has suddenly gone up a notch.

They also brought a lot of buckets and kept carrying water from the pressurized wells to water the saplings.

The trees here have been completed, and the construction team over there has also laid the foundation.

In the middle of this, Xiao Wu took a camera everywhere to take pictures to commemorate.

It was getting late, and the two captains came to say goodbye.

Yan Zixiu said: "Boss Ling, tomorrow is the laboratory glass greenhouse, including the test bench and glassware inside, all handed over to you." Boss Kui, tomorrow I plan to build another cherry blossom wall around this circle of the research institute, the kind where the cherry blossoms bloom in all seasons. Also, please tell my teacher to bring the Ningshen grass and nutrient solution for breeding. These boxes of water spirit pears, you take them and divide them. ”

The two captains thanked them and said goodbye and drove away with their people.

Where did they go? Going to a place where no one is, of course.
