Sure enough, this kid has a way to deal with the locust plague, and the noble person that Yuan Lao Immortal said is this kid, Li Shimin said secretly. I am also extremely glad in my heart, fortunately, this Du Chengfeng has a perfect strategy, otherwise he will be questioned by the people again.

Du Chengfeng continued: "As the saying goes, locusts become locusts after a long drought, and the formation of locust plagues is related to the long-term drought of the land, and it generally takes 60 to 200 days for locusts to develop into adults from their eggs through locusts (locust larvae), and in this cycle time, we have enough time to kill locusts." ”

"First, encourage the people to plant more soybean fruit trees and other trees, locusts like to eat corn, wheat, sorghum, rice, etc., but do not eat soybeans and fruit trees. Second, it is necessary to inform the people to do a good job of drought prevention and to avoid the land being too dry as much as possible, because the locust eggs are hidden in the dry soil, and the locust eggs cannot survive if the soil is slightly moist. ”

"If irrigation conditions cannot be guaranteed, proper and frequent ploughing of the land is also a method, and locust eggs can be killed by exposure to the sun in the early stages. Third: a large number of breeding locusts of natural enemies, chickens and ducks, the more the better. An average chicken or duck eats thousands of locust larvae a day. ”

"After the locust plague, chickens and ducks are also a delicacy, and at the same time, it is forbidden for people to prey on frogs and other frogs. Frogs are also one of the natural enemies of locusts. Fourth: Encourage the people to catch locusts by themselves, locusts are not only a good traditional Chinese medicine, but also fried in oil is also a rare delicacy. ”

Du Chengfeng told the four methods of controlling locusts that he had read on the Internet before. These four methods of controlling locusts have been summed up by countless experts and historical experience, and the results are very obvious. Basically, as long as these four points are done well, the locust plague will not be so terrible.

After listening to Du Chengfeng's four locust control methods, Li Shimin and Chu Suiliang were stunned, and they didn't know how to describe their feelings. The locust plague, which was extremely terrible in their eyes, was easily solved by Du Chengfeng as a pediatric.

A group of so-called ministers, the so-called pillars of the country, pondered for a long time and didn't come up with a plan, and Du Chengfeng was here at their fingertips.

Alas, I only blame myself for not reading much, at this moment, Li Shimin and Chu Sui both have the same idea in their consciences.

Li Shimin felt it even more, because Du Chengfeng had talked to him about the harmfulness of Confucianism a few days ago. Confucianism regards Confucianism as the root of everything, and believes that as long as Confucianism is thoroughly studied, anything can be solved.

It is now clear that there is certainly no such more useful knowledge of statecraft in the Confucian books. Du Chengfeng can name these effective methods of locust control, most of them are from a wide range of books.

What is the locust plague about, the locust plague is related to the people's livelihood, and the people's livelihood is related to the fortune of the country. Therefore, people's livelihood is also the focus of governing the country, blindly respecting Confucianism, and ignoring more hundred schools of thought, people's thinking has been restricted for a long time, it is really like sitting in a well and watching the sky, and what you see is always that small sky.

"Du Chengfeng, your knowledge and erudition have once again surprised me. In front of you, I seem a little lonely and ashamed, and I can see it through the management of this locust plague! Li Shimin laughed at himself.

Du Chengfeng smiled and said, "The emperor has won the award, these are all trivial matters." ”

"Du Chengfeng, I'm a little curious, can that locust really be eaten?" Li Shimin asked suspiciously.

"The emperor can rest assured, not only can you eat it, but it is also very delicious to eat fried and eaten, and the kid ate a lot when he was young." Du Chengfeng said indifferently.

"In that way, I am completely relieved. We will arrange for officials from all parts of Guanzhong to announce these locust control plans as soon as possible, and try to do all this as much as possible before the locust plague comes. Li Shimin said with relief.

"Your Majesty, in fact, as long as the first three are done well, locust plagues will basically rarely occur. And these three articles must also be maintained for a long time, which does not mean that once they are eradicated, the locust plague will never pose a threat. As long as the weather is dry for too long, the locusts will resurge. Du Chengfeng solemnly admonished again.

Then he said: "Your Majesty, the most important point is that it is imperative that the local government stores as much food as possible before next autumn for emergencies. In addition, the kid has another thing, and the emperor can vigorously promote the planting before next autumn," Du Chengfeng took out a sweet potato from his arms and handed it to Li Shimin.

When I came, I considered that the grain output in the Guanzhong area will be greatly reduced after a long drought next year, and when I poured, I could popularize and plant this sweet potato in the Huainan area, so as to reserve some food for emergencies, after all, the yield of sweet potatoes can be much higher than that of rice.

"What is this?" Looking at the palm-sized sweet potato in his hand, Li Shimin looked curious.

"Your Majesty, this is a sweet potato, suitable for growing in areas with soft soil. With a little care, the yield of dozens of stones per mu is not a problem. In addition, sweet potatoes can be eaten in a variety of ways, and they are very suitable for non-staple food and natural disasters. Du Chengfeng's tone was light, and the corners of his lips were slightly raised, as if he was talking about a very ordinary thing.

"What? Dozens of stones? As soon as Li Shimin heard this output, he jumped up from the couch with excitement, and his eyes were even a little moist.

As for Chu Suiliang, he was already stunned on the side. In the past few days, I have always followed Du Chengfeng, and some unimaginable things in the past have become very common here in Du Chengfeng. His nerves had become numb.

A few days ago, Du Chengfeng offered a high-yield rice with a yield of more than ten stones per mu, which was already incredible in Li Shimin's opinion. Today, Du Chengfeng offered another kind of grain that can produce dozens of stones per mu, and Li Shimin felt that no matter how strong his heart was, he couldn't withstand so many surprises and fright.

It's like sitting in a cloud all at once, falling to the bottom all at once, and floating back to the clouds at the same time. It was really this Du Chengfeng who surprised him one after another, Li Shimin felt that he could handle the winds and waves he had experienced in his life, but this Du Chengfeng made him unable to control his emotions again and again.

"Chu Aiqing, you tell me, is this true? I'm not dreaming, am I? Li Shimin tears rolled in his eyes, and he looked at Chu Suiliang and asked hopefully.

Chu Suiliang suddenly broke out in a cold sweat, Your Majesty, I'm also in a daze, right? Anyway, did you ask the wrong object, shouldn't you look for this Du Chengfeng to confirm?

Of course, as a courtier, he definitely didn't dare to say such words, so he could only reply stubbornly: "Back to the emperor, it's true, Weichen can hear it clearly." ”

"Good! Good! After Chu Suiliang's confirmation, Li Shimin excitedly stroked the sweet potato in his hand and applauded.

After a while, Li Shimin calmed down his emotions and said to Du Chengfeng gratefully: "Du Chengfeng, thank you for the people of the world!" ”

"The emperor doesn't have to be polite, the kid just can't bear to see the people of Guanzhong suffer. Natural disasters cannot be stopped, but in the face of natural disasters, we must not leave our fate to fate, and there will always be solutions. Du Chengfeng said.
