319.Li Pojun Dengchu (22)

Li Pojun thought about it in bed for a long time, and suddenly, he got up straight, didn't wear a coat, and shouted outside: "Qiu'er, spread paper and study ink."

Xiao Qiu'er, who was sleeping in clothes outside, heard that she was busy, so she put on a piece of clothing and hurried over.

With his hands and feet, he quickly laid the paper on the desk for Li Pojun, and polished the ink.

Li Pojun picked up the wolf pen and dipped it in ink, only to see that it was written on the paper: "Three strategies to prevent locusts." The four words are drawn with iron hooks and silver, standing alone.

After a moment of thought, he wrote: "

Minister Li Pojun has a book.

The minister recently heard that the locusts in the land in Guanzhong were raging, and the people were suffering, and his heart was very painful, but he also heard that the Son of Heaven could cure the locusts by building a platform to sacrifice to the heavens, and he laughed at it.

The husband and the king, the son of heaven, the destiny of heaven is also returned, how can the people under the rule of today suffer from the scourge of birds and insects? If the pest of a mere bird or insect makes me guilty of myself, what use do I want to wait for my courtiers? It's ridiculous, and it's ridiculous.

Therefore, the minister has read all the miscellaneous books and strange doors, and has also visited the field, exhausted his efforts, and now played three strategies to prevent locusts.

First: agricultural prevention and control.

The main methods of agricultural control can be summarized into three types:

One is to reduce the food sources for locusts. Locusts mostly eat crops such as corn, wheat, sorghum, rice, and millet, but do not eat soybeans, alfalfa, fruit trees, etc. Therefore, the ministers thought that planting as many soybeans, alfalfa, fruit trees and other trees as possible in the locust area could control the locusts.

The second is to reduce the habitat of locusts. Some locusts occur in low terrain, and all localities can transform such plots into ponds to raise fish and shrimp, which can greatly reduce the locusts' living grounds and better control locusts;

Third, reduce the spawning grounds of locusts. If His Royal Highness the Crown Prince orders to increase the intensity of afforestation, increase the number of plants, and make the plant coverage reach more than seven or eight out of ten, then such a plot will no longer be suitable for locusts to lay eggs, and the great damage of locusts can be reduced. In the middle of the Tang Dynasty, due to the Yellow River, most of the land is eroded, which not only causes the fertility of the land to decline, but also promotes the reproduction of locusts. If fruit trees and beans are planted on this soil erosion wasteland, it can not only increase the food ration, but also inhibit the reproduction of flying locusts.

Second: biological control

Organisms, living organisms, have the ability to grow, develop, reproduce, etc., and can exchange substances with the surrounding environment through metabolism. Animals, plants, and microorganisms are all living things, that is, they refer to all living objects in nature.

There is a saying in "The Book of Rites and Music": "If the soil is empty, the grass and trees will not grow, the fish and turtles will not be big if the water is troubled, and the creatures will not be able to do so." ”

Chen summarized that the second of the three measures for locust prevention and control is biological control, and there are two main methods.

First, the protection and use of the natural enemies of local locusts to control locusts; Second: herding chickens and ducks to control locusts.

Natural selection, survival of the fittest, the immutable principle of the world, is the same in the animal kingdom, locusts also have natural enemies, such as cats and mice, birds and insects. The protection and exploitation of the natural enemies of the local locusts is precisely the so-called enemy of the enemy is a friend, and the situation of the locusts is even more unbearable when the enemies of the locusts increase. There are many natural enemies of locusts, including frogs, lizards, birds, nematodes, various beetles, various flying bees, and various flying flies. It is common knowledge that birds eat insects, and a single bird can often eat hundreds

and even thousands of locusts, which can be said to be powerful.

According to the minister's statistics, the hardest-hit areas of the Datang drought locust in our country are shrike, gray magpies, magpies, grass herons, starlings, ants, foot bees, corianders, young bee flies, insectivorous flies and other dozens of insects are important predatory natural enemies of locusts. This kind of talk is by no means vain, and the enemies of the locust plague can also see more of their locust eating.

If you want to prevent locusts, you can plant more plants that attract natural enemies of locusts, such as flying bees and coriander larvae prey on locust eggs, and adults feed on nectar or flowers, so you can plant flowering plants in the locust occurrence place to provide supplementary food for natural enemies and increase the number of natural enemies, so as to control locusts.

Third: physical control.

These methods are all entangled in the wisdom of the predecessors, simple and practical, the ministers remove the dross, take the essence, and exhaustively summarize the following six points, I hope that Your Majesty will implement them as appropriate.

First: Seal the lock. Locusts are migratory pests, and they can be sealed at the edge of the farmland for unified joint control.

Second: manual killing. When the insect population density is not large, it can be organized to manually cast nets to kill, turn harm into treasure, feed poultry or make animal feed.

Third: trenching method. Ditches are dug on the avenue to drive locusts into the ditch to kill, mainly used to control locusts.

Fourth: Bonfire booby-trapping. Use the phototaxis of locusts to lure them into fire, and it is better to use them on moonless nights.

Fifth: digging up locust eggs. According to the biological learning of locusts, find the places where the locusts lay their eggs, "that is, dig them up, boil them in water, or burn them with fire."

Sixth: to drive away locusts with color and sound. Color to repel locusts, that is, to borrow the bright colors of clothing and flags to repel locusts; The sound drives away locusts, mainly using the strong piercing sound of bronze and firearms to intimidate flying locusts.

Although the minister is not talented, he also tries his best to share the worries of the king. The ministers begged His Majesty, decided to prevent locusts in advance, and went up to the heart of heaven and the community to save the people.

Honest and fearful, Weichen grass.

July 3rd of the 9th year of Wude. ”

After writing the whole article in one long speech, Li Pojun shook his wrist, it was really sour, and in some places due to the consideration of vocabulary, there were still some ink marks and ink marks in the way of thinking and writing.

was about to ask Xiao Qiu'er to help transcribe a copy, but after thinking about it, it seemed a bit ridiculous to hand over such an important matter to a little maid, not to mention that this was the first book in his life, which also had some meaning. Moreover, this is just an ordinary piece of rice paper, not a transcript.

Immediately, Li Pojun instructed Xiao Qiu'er, "Take a recital."

Xiao Qiu'er was stunned for a moment, and asked in surprise, "Lang Jun, is this going to be played?"

Li Pojun smiled and nodded.

Xiao Qiu'er was busy looking for it, the book has its own thing, but Li Pojun has used it again, so Xiao Qiu'er rummaged through the cabinet and finally found a mess, there was still a little dust on it, Xiao Qiu'er was busy taking the silk cloth to wipe it and hurriedly handed it to Li Pojun.

Shaking the sour wrist, Li Pojun lifted the wolf pen, it was the next pen, this time there was a draft, since the dragon flew and the phoenix danced, the thin gold calligraphy with an iron hook and silver stroke jumped on the paper, very beautiful, and seemed to reveal an independent demeanor.
