Lu Bu sent someone to invite General Diannong Han Hao to discuss how to prevent locusts from harming.

Han Hao has been favored by Lu Bu for more than a year, and he is really capable. Under his management, the military farming corps have been prosperous. Whether it is grain planting, animal husbandry, or minerals, they have developed rapidly, and have become a strong support for Lu Bu's battle for dominance in the world. Although other princes are imitating Lu Bu for military farming, it is obvious that they are much behind.

The military farming corps developed too rapidly in the past year, with more than 2 million people, so some people suggested that Lu Bu divide the military farming corps according to the prefectures. Lu Bu divided the military farming corps into the Jizhou Construction Corps, Bingzhou Construction Corps, and Shuozhou Construction Corps. Now Qingzhou is about to be completely occupied, so the Qingzhou Construction Corps was established.

Although these corps are under the command of General Diannong Han Hao, after all, the Diannong Generals of the Construction Corps in these states have the power to report directly to Lu Bu. Han Hao's power has been weakened a lot. If a narrow-minded person would definitely be dissatisfied with Lu Bu.

Han Hao was very open-minded. He thought that before he met his lord, he was just a Hanoi county official who was not valued. After meeting Lu Bu, he was promoted to General Diannong for more than a year, and his power was even greater than that of the general state governor. Although such a kind of kindness of knowing was broken, he was willing to refuse to be divided. Being divided into power was also beneficial to him. If the power at hand reached the point where he was so powerful that he would be difficult for him to get along with his lord in the future. The wise Han Hao accepted the plan of the military farming corps by state very readily.

Han Hao had a deeper understanding of Lu Bu over the past year. Once Lu Bu trusted someone, he was not particular about the details and was not arrogant in front of that person. Han Hao could fully see from Lu Bu's attitude towards him. The lord trusted him because Lu Bu had just taught Lu Lingqi, Zhuge Liang, Lu Xun, Lu Meng, Wu Ban, Ju Hu and others martial arts in the Boy Scouts Command behind the General's Mansion, and he was sweating profusely. Without changing clothes or making any decorations, he took Han Hao into the meeting room of the Military Council in the front house of the General's Mansion.

Lu Bu handed Han Hao a piece of paper, which was a statistics on the rain last year. The rainfall in the twelve months of the whole year could not catch up with the three months of rain in Luoyang the previous year. It can almost be said to be a drought throughout the year. The people in the areas under the rule of the Yecheng imperial court took river water and well water to irrigate. There were many severely arid areas that could barely plant crops by digging ditches to build water conservancy. They could barely supply domestic water.

Although the drought is like this, there is nothing to be afraid of, because the waters of the vegetation in the Eastern Han Dynasty were far better than those of later generations. The drought at this time did not last for many years like the late Ming Dynasty, so Han Hao was not worried.

He glanced at a pile of soil in the chamber, which was very dry and cracked, and asked, "Lord, are you worried that the lack of rain will affect the harvest this year?"

Lu Bu shook his head with a serious face and said, "In the past year, we have built many ditches and irrigated them well. Although the crops did not grow well last year, they will not reduce the yield too much. My only worry is that there may be locust plague this year!"

Han Hao was shocked and said skeptical: "Lord, it's only February now, can you infer that there will be a locust plague this year?"

Lu Bu rubbed a piece of soil and handed it to Han Hao: "Yuansi, look, the soil in Hebei is so dry, which is the most suitable degree to which locusts reproduction. As the saying goes, long-drought will lead to locusts. This is a painful lesson. A locust plague this year is probably inevitable."

Han Hao looked ashamed. This was originally something he had to know as a general named Diannong, but it made the lord worry. Lu Bu's words were like a bolt from the blue, which made him wake up instantly. He knew that the drought has continued since this autumn, without autumn rain, and only one winter snow has fallen. It is spread all over the fields, and the locust eggs in the soil on the river bank are buried there safely. After waiting for three or four months, it will erupt. At that time, wheat everywhere will become food in the mouths of locusts.

Han Hao vaguely remembered that many years ago, the land of Jizhou was drought and rainy for a long time, and the fields were dry and cracked, and swarms of locusts appeared everywhere. When the locust swarm flew by, a large area of ​​darkness was blocked, and even the sun was blocked. Wherever the locusts went, the crops in all places were gnawed. At that time, the people were ignorant and worshiped the locusts as gods, and did not dare to kill the locusts and eggs. They only prayed that they would leave their own crops or throw the locusts into other people's fields, causing the pests to become more and more intense and the people had no harvest. At that time, the local officials at that time still levyed levies, starved everywhere, and the people were living in poverty. Therefore, Zhang Jiao took the banner of the Yellow Turban in Jizhou, which was closely related to the locust plague.

Seeing Han Hao's expression, Lu Bu knew that he believed what he said, so he asked happily: "Yuansi, do you have any good plans to destroy locusts?"

Han Hao thought for a moment and said, "First of all, it is to eliminate the ignorance of the people. Those ordinary people who are fighting think that the locusts that are overwhelming are locust gods. When the locust plague comes, it is a disaster that is coming from heaven. The people are powerless. They dare not kill locusts. They just kneel down on the ground and pray to the locusts to leave their fields. This idea is very wrong, which leads to the great locust plague that happened several years ago.

Now that the locust plague has not yet broken out, we have time to educate the people and let them realize that locusts are just ordinary insects and can be killed. As long as we work together to destroy locusts, even if the locusts are harmed, they will not cause a thousand miles of naked land."

Lu Bu nodded and smiled, "Yuansi, you are right.

The former miracle doctor Bian Que once said that his elder brother was curing his illness before the onset of the disease. At that time, the patient did not feel sick, but he applied medicine to eliminate the root cause of the disease, making it difficult for people to recognize his medical skills, so he was not famous, but was highly praised in Bian Que's family. Bian Que's second brother was curing the disease when the disease first started. The symptoms were not very obvious and the patient did not feel pain. The second brother could cure the disease, which made people in the village think that the second brother was just a small disease. Bian Que was treating the disease when the condition was very serious. The patient was in great pain and the patient's family was anxious. At this time, they saw Bian Que puncture the meridians, bleeding with needles, or applying poison to the affected area to fight the poison, or undergoing major surgery to point directly to the lesions, so the serious patient's condition was relieved or cured quickly, so I, Bian Que, heard about the world.

After-control is not as good as during-process control, and during-process control is not as good as before-process control. Unfortunately, most people have not realized this. They only seek to make up for it until the matter is so serious that it is a mess. Of course, it is famous, but more often it is time to make up for it, and it is too late."

Han Hao laughed and said, "What the lord said is that we must prevent problems before they happen, prepare for the future, and dare to take all measures to deal with the outbreak of locust plague before the outbreak. According to the experience of his subordinates over the years, since locusts prefer dry soil, we will build more water conservancy and irrigate more, and strive to ensure that although the weather is drought, the fields are not dry. Since the locust eggs are hidden in the soil, we will cultivate a large number of wastelands, turn them out, and kill them in advance. At the same time, plant trees and afforestation to change the weather in areas where locusts are flooded, and reduce suitable sites for locust laying and reproduction. We can further cultivate and dig deep into the fields to reduce locust eggs, which will greatly reduce locust plague."

Lu Bu smiled and said, "Yuansi, your measures are very good. You will formulate these measures into articles. The Ministry of Revenue issued a document asking local governments to actively promote them so that people from all over the country will actively start to eliminate locust eggs from now on."

Lu Bu asked again: "Yuansi, eliminating locust eggs in this way is not enough to kill all locust eggs. At that time, a large number of locusts will still be breeding, endangering the crops. How do you plan to kill these locusts?"

Han Hao thought for a moment and replied: "The sentence "Praying the Fire" in the Book of Songs refers to the use of fire to trap locusts at night to eliminate them. In this dynasty, there were methods of destroying locusts in the Han Dynasty. First digging trenches on the ground and by the roadside, then everyone lined up, holding branches, wooden sticks and other things in their hands, waving and shouting, driving the locusts into the deep ditch on the ground, and then burying them with soil."

Lu Bu shook his head gently and said, "Yuansi, using this ditch method to bury the locusts, it also burys hidden dangers. The locust's life is very strong. Even if it is cut by a knife and axe, it may not kill it. It was originally drilled out of the soil. It cannot damage its life if it is buried in the soil. It will soon harm the crops again."

Han Hao said in surprise: "Master, what should we do?"

Lu Bu thought for a moment and smiled and said, "You can burn and bury the methods on the Book of Songs with the method of ditching. At night, you can light a fire next to the dug ditch. The locusts fly into the fire and are burned to death when they see light. Then sweep into the ditch to bury them. Locusts like to be dry and die when they enter the water. They can also throw the captured locusts into the water and drown them. If they are rushing locusts, it is best to have dew on the locust wings in the morning, and they will be poor in jumping and flying, so it is easier to catch them."

When Han Hao heard Lu Bu say this, he smiled happily and kept nodding. He wanted to find Bi Mo to write down these things. Lu Bu waved his hand and pointed to the secretary Ling Lucui behind him. Lu Cui had quickly recorded all the words of Lu Bu.

Lu Bu lived in the countryside for a period of time in later generations. He knew that humans in later generations had two assistants, one was a frog and the other was a bird.

Frogs live in the same type of ecological environment as locusts. Low-lying areas with reeds and weeds, ponds, ditches, etc. are their good places to live. Therefore, frogs are the vanguard forces that restrict the survival and reproduction of locusts. A frog can eliminate more than 10,000 locusts in a summer; a frog eats an average of 50 locusts every day, and the maximum can reach 266 locusts. Even a toad with a dull body can prey on nearly 10,000 pests in three months in summer. According to this calculation, as long as there is an average of one frog in the two-square meter farm, it is enough to suppress the survival of locusts.

Some birds eat insects. In the brooding stage, birds that eat locusts need to prey on a large number of locusts. Taking ordinary swallows as an example, a pair of biological birds and a nest of chicks can eat more than 16,200 locusts per month. (To be continued)
