So he directed the topic in this direction.

"There is no good solution now. When there were no pesticides in the past, villagers had to sow more seeds to grow wheat and leave some for bugs to eat. Now with pesticides, it seems that some seeds have been saved, but it is very detrimental to people's health.

"Zhang Zhiju sighed.

"Teacher Zhang, isn't there perennial wheat? Once sown, it can grow for several years?" Yan Zixiu asked.

Zhang Zhiju was surprised: "Xiao Yan, you have good knowledge. There are international studies on perennial wheat and perennial rice. However, it is difficult to balance taste and yield."

Perennial crops actually have more than just the benefit of less pesticides.

For example, wheat is harvested once a year. After the harvest, the land must be plowed. Nitrogen in the soil will be released into the atmosphere, causing climate change. Nitrogen, phosphorus, and potassium are three elements. If they are missing, the yield will be affected. And among them, nitrogen is the most easily lost. Loss

When the soil is plowed, nitrogen fertilizer must be applied again. When the plowed land encounters rain, not only will the soil be lost, but surface water will also be polluted.

Perennial wheat is planted once and harvested continuously for many years. The first season is the same as conventional wheat production. From the second season on, production only requires two production links: field management and harvesting. Farmers only need to plant once and harvest continuously for several years.

or longer.

It's like sugar cane or leeks, it grows again when cut, and it grows again when it grows, and it goes on and on. The same goes for perennial rice.

"Teacher Zhang, do we have any research in our country?"

"Yes. My teacher is studying this topic. But the progress is very slow." Zhang Zhiju felt helpless.

"Is it very difficult?" Yan Zixiu wanted to know where it was stuck.

Zhang Zhiju said: "One is that there are too few samples for reference, and foreign technology is blocked for us. The other is that manpower is sometimes poor. My teacher said that sometimes he seems to have reached a threshold, but it seems a bit illusory."

Yan Zixiu understood that on the one hand, it was because the contact surface was too narrow, and on the other hand, it was because of his intelligence.

He used the Time Recall Technique and the Qi Watching Technique to look at Zhang Zhiju, and found that both Zhang Zhiju and his teacher had four to five inches of white light on their heads. They were both kind and righteous people and worthy of trust.

So he had an idea, took out a cloth bag from his carry-on bag (Xianfu), and took out two packs of Enlightenment Tea (special educational tea), and handed them to Zhang Zhiju: "Teacher Zhang, you and I share the same goals, and we both want to

May everyone be prosperous and healthy. Inside this bag are some relevant results of my teacher’s research; I also invite you and your teacher to taste these two packs of special educational tea.”

Zhang Zhiju was very surprised. How could such a major scientific research achievement be given away casually? He hesitated and said, "Isn't this inappropriate?"

"Teacher Zhang, to tell you the truth, I am very busy right 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 Autumn Canton Fair. Now I am too busy with all this. And you guys

I happen to study the field of perennial crops. For people like us, no matter who accomplishes something, as long as it benefits the people, isn't it the same?" Yan Zixiu said sincerely.

"Xiao Yan, I have never met your teacher. But from you, I can feel his big heart. As long as it is beneficial to others, why should the credit go to me. I admire this kind of character." Zhang Zhiju was very impressed.

Touched, he accepted the things and said, "Okay. No matter how pretentious I am, I will still be sorry for you."

He couldn't help but feel ups and downs in his heart.

Because of this perennial wheat, there is no need to re-plow the land or re-sow, thus protecting water and soil, reducing the use of pesticides and chemical fertilizers, saving a lot of labor and material resources, and effectively utilizing idle fields.

This has far-reaching implications for the sustainable development of agriculture.

Yan Zixiu laughed: "Teacher Zhang, the ancients said that a white head looks like new and a head looks like the same as before. This probably refers to you and me."

"Haha, that's right. Whether we are close or not depends on the relationship. If we are like-minded, we are close. It's you and me." Zhang Zhiju said happily.

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

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

…

He did another great thing for the people, and Yan Zixiu felt very happy.

Back at the base, he said to Xiao Wu: "I've contacted you about the tree wall. I think we'll be there at five in the afternoon."

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

It is obvious that these workers are skilled, hard-working and have built a sewage purification pool in the corner of the base. The purification pool is three-thirds the size of a floor and has a glass cover.

Xiao Wu looked very satisfied and felt that the construction team Lao Yan had found was reliable.

"Lao Yan, why don't you give Shuiling pears to these workers? I see you giving them to whomever you catch." Xiao Wu asked.

"Well, I'll give them a few boxes later." Yan Zixiu felt that loopholes would appear from time to time.

At 4:30, three more trucks arrived, hauling two loads of saplings and a load of workers, and roared to the base. Twenty or thirty people got out of the truck.

Yan Zixiu and Xiao Wu stepped forward to greet him.

"Hello, are you Boss Wei introduced by my teacher? I am Yan Zixiu." Yan Zixiu shook hands with Lingpuppet No. 2, "This is the Chief of the Martial Arts Section."

"Chief Yan, Chief Wu, hello."

"Hello, Boss Wei, you are so efficient." Xiao Wu shook hands with Lingpuppet No. 2.

"Section Chief Yan's teacher takes this matter very seriously, so we rushed over." Lingpuppet No. 2's acting skills are not bad.

"Okay. Let's talk about the gossip later. Look at this base. It has 200 acres of land and a circumference of about 1,400 meters. To plant one tree every 2 meters, it takes about 700 trees. Leave these areas aside

Space will be the entrance and exit in the future." Yan Zixiu pointed.

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

They came to the field with shovels and saplings. They skillfully dug holes, set up trees, and filled the holes. One spirit puppet planted more than twenty trees. In less than an hour, they were done.

The saplings of the Ruyi Spirit Tree are three feet high. One is inconspicuous, but more will make it look better.

Looking at the circle of three-foot-high verdant Ruyi Spirit Trees, Yan Zixiu felt a sense of accomplishment, and Xiao Wu was also very satisfied.

Everyone feels that the base has suddenly gone up a notch.

On the 2nd, they also brought a lot of buckets and continued to carry water from the pressure well to water the saplings.

The trees here are done, and the construction team over there has also laid the foundation.

During this time, Xiao Wu took his camera everywhere to take pictures as a souvenir.

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 Wei, tomorrow I plan to build another cherry blossom wall around the scientific research institute.

The kind where cherry blossoms bloom all year round. Also, please tell my teacher to bring the Ningshen grass and nutrient solution specially used for breeding. You can share these boxes of Shuiling pears."

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

Where did they go? To a deserted place, of course.
