"Qiuping, come here, measure the basic parameters of the rice in this paddy field." Yuan Lao beckoned to a young and beautiful student behind him. This is an intern at the Rice Research Institute. The girl's name is Kang Can, and her parents have some dealings with Yuan Lao. So this time I came out and brought her out.

"Hey." Kang Can answered, and came over to measure.

The parameters to be measured are nothing more than the number of spikes per plant, the number of grains per spike, the weight of 1000 grains, as well as plant height, spike length, and seed setting rate. However, it will take some time to complete all of these items.

Yuan Lao arranged the task and didn't bother anymore, because he saw something that interested him more.

"Old Yuan, what novel things have you seen?" Old Man Luo asked.

"Hey, that's interesting. In this whole field, there is not a single lesion on all the leaves. And there are very few insects in this field. There are especially many frogs. How did he do it? Yuan Lao was very surprised. This was definitely the first time he had seen such a situation.

Under normal circumstances, when harvesting, when the seedlings fall, countless moths will fly out of the seedlings, and the number is amazing, especially in such a large area of farmland, when harvesting, all the pests will be driven out of the field. At this time, experienced farmers will prepare pesticides to kill the insects that are driven out of the rice fields. Otherwise, when it is time for the late rice to be planted, the moths will fly back into the field and lay eggs on the tender green seedlings.

However, after the rice fields in Laiwang were harvested, there were very few insects because there were many frogs in the rice fields. This keeps the number of moths in the paddy fields at a very low level. Now that the seedlings have been harvested, the pests have lost their umbrella to hide from the frogs. The frogs in the rice paddies got busy.

This is a very difficult situation to see in modern farmland. Because of the heavy use of pesticides and fertilizers, the number of frogs is becoming less and less. Many people blame the decline in frog populations on farmers' catches. This is actually incorrect. Frogs lay a huge number of eggs at a time. The rate at which frogs reproduce is also very staggering. So, the real reason for the massive decline in frogs is pesticides and chemical fertilizers. The human capture only exacerbates the problem.

"What's wrong?" Old Man Luo asked. Old Man Luo is a layman. Naturally, I couldn't see what Yuan Lao could see.

"Have you noticed that there are very few bugs in the rice fields? And there are a lot of frogs? This is the real ecological farmland! Such an ecology is formed, and almost no pesticides are needed. Without the use of pesticides, there are more frogs. There is a balance between the number of frogs and the number of insects. As the number of insects increases, the frogs have more food and their reproduction rate increases, and the more frogs there are, the fewer insects, and finally the frogs reproduction rate decreases due to lack of food. This creates a balance. That's not even the best. Yuan Lao said.

"The most powerful thing. The seedlings in this paddy field never seem to have been sick. Yuan Lao pointed to some of the rice seedlings that were still green and said, "You see, all the leaves don't have any disease spots on them at all." Either the rice is very resistant to disease, or the rice has not been diseased at all. ”

Not far away, Jin Gui walked around the field barefoot and carrying a small fish basket, and saw a small sleek hole in the paddy field, and immediately turned the whole ball of mud out. Then the mud is placed on top of the basket and broken, each time a loach can be broken out of the mud.

"Loach!" Old Man Luo was very excited. In the past, when I was sent to the countryside, my favorite food was loach. At that time, the living conditions were very difficult, but there was a time when life in the countryside was able to improve. Loach digging is one of them.

At that time, there were a lot of loaches in the fields. When threshing rice, there is a time when some loaches can be shaken out under the vibration of the threshing machine.

At that time, there was a shortage of cooking oil. When cooking the loaches, throw the live loaches directly into the pot. Cover the pot with a lid and bring the heat to a boil. After a while. You can hear the loaches jumping in the pot, and after a while there is no movement.

Lift the lid at this time. The loaches in the pot have turned white. If you can get a little sesame oil, that's the best outcome. Frying in a pan of oil is a bit too extravagant. Generally, the sesame oil is dropped in the spatula, and the sesame oil is rotated along the edge of the pot to let the sesame oil flow slowly to the bottom of the pot, so that the loach is slightly stained with oil stars. Add the chili peppers and put a little salt. A delicious loach feast is complete.

Old Man Luo and Old Yuan had both been in the countryside for a long time before. So they're all familiar with loaches. also learned from Jin Gui to turn up loaches in the field.

"Jin Gui, come here, borrow your fish basket and use it." Old man Luo's sword is not old. It didn't take much time to turn out a chubby loach.

Old Man Luo grabbed a grab of sugar particles for Jin Gui today, the effect was very good, as soon as Jin Gui heard Old Man Luo's call, he immediately ran over with a fish basket.

The little girl kept shuttling in the mud, like an elf.

"Grandpa Luo, I caught a lot of loaches today." Jin Gui said.

"How about going to the farm at night to make a tooth sacrifice? I still have a bag of sugar particles somewhere! "Old Man Luo turned into a cunning old version of the gray wolf at this moment.

"You have to have it." Jin Gui has obviously become the lazy sheep who is deceived every time.

"Hehe, I also caught a loach, Jin Gui come quickly!" Yuan Lao smiled with joy. However, the loach in the mud in his hand seemed to sense the danger and wanted to drill out desperately.

Jin Gui ran very fast and hurriedly put the fish basket under Yuan Lao's hand. Just followed by the falling loaches.

"Hehe, that's clever!" Yuan Lao praised.

The people of Tunli have long been surprised by Old Man Luo rolling up his trouser legs and beating him barefoot in the field. The people in this city had nothing to do when they were full, so they went to the countryside to live a peasant life. What's so unusual about catching loaches like a child?

There are a lot of loaches in this rice field. As soon as the pesticides and fertilizers stopped, the number of loaches slowly accumulated.

"Oh, in this way, it is not without reason that this rice field is highly productive. Without pests and diseases, this yield can be increased by at least 10 percent. The activity of loaches in this soil can not only improve the soil structure of the rice field, but also provide nutrients for the rice. It's a lot to kill. Only when the rural rice fields develop in this way can there be hope. Yuan Lao said.

"That's true. No matter how high the yield of the rice you have researched is, it still needs to rely on pesticides and fertilizers to maintain it when applied to the field. How can the quality be high? Old Man Luo said.

"Even if biotechnology is used to develop insect and disease resistance genes, not to mention the risks, it will not be able to fundamentally solve the problem. Seed improvement strategies are only one part of farmland management. Cultivation systems and management levels are equally important. Yuan Lao said.

"Let's go, almost. Let's go over and see what the data measured by Xiaokang is! Yuan Lao went up to the ridge, washed his feet in the ditch, still rolled up his trouser legs, beat his bare feet, and lifted the leather shoes with his hands.

"Well-off, how's it going? Have all the conventional parameters been determined? Yuan Lao asked from afar.

"Teacher Yuan, the data is amazing! Comprehensively surpassing ordinary rice. Kang Chan said.

"Quick, I'll take a look at the data." Yuan Lao said.

"Each ear of grain is nearly 700, and the weight of 1,000 grains has reached 50 grams. These parameters are nearly 50 percent higher than those of ordinary rice. It's amazing. Kang Chan said.

In fact, this astonishing result carries with it some inevitability. Kang girl, you have to summarize the characteristics of this farmland and find out the reasons for the high yield of this farmland, this can be regarded as the homework I assigned to you. Coming out for an internship is not a tourist. Gotta learn something real. Yuan Lao said.

"Hey. I'll sum it up. Kang Can smiled.

It was almost dark when Laiwang finished harvesting this paddy field. At this rate, three days should be enough time to harvest all the farmland. But the weather is elusive. The sooner the harvest is completed, the sooner you can rest assured.

"Xiao Zhao. We meet again. Yuan Lao took the lead in greeting Laiwang.

"Hello Yuan Lao. You are welcome to visit us in Zhaojiatun. Lai Wang said with a smile.

"I'm here to learn from it. Your level of rice cultivation is not ordinarily high. This is the true organic rice production I've seen so far, and it's the most managed growing base. The ecosystem of farmland is the most intact. I really don't know how you got to this point. It's not easy, indeed. Yuan Lao said.

"I'm all fools. I just don't want to use pesticides and fertilizers, so I use soil methods. I didn't expect it to work really well. Lai Wang said with a smile.

"It's not easy. If the whole country had used your local method, there would be no food security problem. In recent years, there have been many problems with this rice. As a food worker, I feel a lot of pressure on my shoulders. But from your farmland, I seem to see a new direction for China's rice development. If all the farmland could be like yours. We're going to have a better time! Yuan Lao smiled.

"I don't dare to say that. This time it was lucky. The wind and rain are smooth. There's really no experience worth promoting. Laiwang said.

Kang Can said, "It's not right for you to do this. If we are conservative and do not promote cultivation techniques that are beneficial to agriculture, then how can our agriculture develop? I don't think you're going to have to think like that. ”

"Kang girl, don't talk nonsense. Cultivation techniques are also a form of knowledge. He has the right to choose. Such an attitude of yours is extremely dangerous. It is also profoundly incorrect. (To be continued......)
