Baishui River is one of the birthplaces of the Tuojiang River, an important tributary of the Yangtze River. It has a beautiful ecological environment and is home to giant pandas, golden monkeys, clouded leopards, wildebeests, golden eagles and other rare birds and animals.
Wang Tai followed Liang Shengwen toward the Baishui River. Along the way, he was shocked by the boundless beauty and marveled at it.
The Agriculture, Forestry, Animal Husbandry and Fishery Technical Service Station is located in the middle of Baishuihe Township. It has a typical farmhouse with a low fence, several wooden houses, spacious yards, and several warehouses. Above the door is written "Pengxian Agriculture, Forestry and Animal Husbandry"
"Fishing Technology Service Station".
When everyone entered, no one was seen. Liang Shengwen complained secretly. He never wanted to see this agricultural technology station. This group of people might not be here. If Wang Shangshu saw that there was no one on duty at the agricultural technology station, he would be accused of being lax in his duties.
, but something is very wrong! It is extremely easy for a dignified minister to manipulate a small magistrate!
Fortunately, I met someone in the backyard, one of the two technicians.
Seeing someone there, Liang Shengwen breathed a sigh of relief and shouted: "Where is Chen Huan? Wang Shangshu from Beijing is here to inspect. Please call him out immediately to receive him."
"Stationmaster Chen is explaining agricultural knowledge to farming experts in various townships in the backyard," the technician said quietly.
"Don't call him, I'll go and take a look myself." Wang Tai waved his hand.
As everyone walked inside, they suddenly saw two farmers running out of the house.
One smiled and said: "Brother, how fast can you run?"
Another spat: "It's not a good idea. I suddenly had an urge to urinate halfway through the lecture. I missed Mr. Chen's class. It's a huge loss."
The two men went to the toilet by themselves. Wang Tai secretly took a look at the big room in the backyard. There were nearly a hundred people sitting densely, all dressed as farmers, and a young Confucian scholar was teaching.
"Seed selection techniques for wheat and grass: Wheat seeds can be harvested when ripe, select those with large and strong ears; grass seeds, select tall ones. Seeds with large ears and strong plants, if planted well, the seedlings will naturally be good", then
The Confucian scholar's articulation was clear and his words were correct and round, and it felt like he turned the agricultural books into poems.
"Sir," a farmer raised his hand and asked: "Even if you plant good seedlings and strong ones, it will be in vain if you encounter pests and diseases. Is there any way to prevent and control pests and diseases?"
The Confucian scholar smiled, showing his beautiful white teeth, "Everyone knows that pests and diseases are natural disasters. They can only sigh and do nothing when they encounter them. There are even people who pray to gods and worship Buddha. In fact, pests and diseases can be prevented and controlled. First of all, you can start from
For prevention and treatment during breeding, "The Book of Pansheng" records: "Boil minced horse bones in water, add aconite and soak them. After three or four days, remove the aconite, then add silkworms and sheep arrows (near the vaginal area on the inner thigh) and stir it into a thick porridge.
Finally, adding seeds and soaking them repeatedly can make the crops free from locusts. Horse bones and snow juice can also be used. Secondly, you can plant some vegetables that pests do not eat. The "Simple Book of Famine Relief" records: "Smelly wheat, peas, small potatoes, etc."
Lentils, broad beans, mustard, green onions, chrysanthemums, white radish, rapeseed, round-leaf amaranth, etc., all have spicy and smelly smells, so pests avoid them.
After Wang Tai heard this, he nodded secretly. This young man was very knowledgeable and well-founded in citing scriptures.
"Mr. Chen, you said that although vegetables such as stinky wheat, mustard, green onions, and chrysanthemums can resist diseases and insect pests, they taste too spicy and not many eat them. Is there any other good way?"
"Yes." The young man took a big sip of tea, drank it, and prepared to give a lecture.
Hearing him say "yes", the literate farming experts in the room took out their pens and papers to write down, while the illiterate ones pricked up their ears. In the classroom of nearly a hundred people, there was unexpectedly silence.
Wang Tai was secretly claiming to be surprised when he heard bursts of sweet sounds. The sounds were warm and powerful, just like big beads and small beads falling on a jade plate.
"After cultivating and planting fruits and vegetables that pests do not eat, there are three methods to control pests and diseases. One is the crop rotation prevention and control method. This method is recorded in "Qi Min Yao Shu", "Grow hemp to get good land, and there is no need for ruins. So.
The leaves are also good, and there is a risk of premature leaf failure, so they should not be used for planting. 'Spotted leaves' and 'premature failure' are two diseases that can be transmitted through the soil.
Continuous crop rotation can avoid these two diseases. As far as Peng County is concerned, planting rice in March and April and wheat in September and October can reduce the occurrence of pests and diseases. Remember, crop rotation must be done, and continuous cropping must not be done. If
If you plant one type of crop all year round, the probability of pests and diseases will increase."
"That's it. No wonder the experience passed down by the elders from generation to generation is to plant rice in March and April, and wheat in September and October. That's it." The farming experts below were amazed. They only knew the farming experience left by their ancestors.
, I don’t know why, but after listening to Chen Huan’s talk, I suddenly became enlightened.
"Second, the intercropping method. You should not plant only one kind of fruit and vegetable in a piece of land, but should mix seeds. Agricultural books from the Wei, Jin, Southern and Northern Dynasties recorded that 'Mung beans and adzuki beans are often planted under the mulberry seedlings to make the two beans beautiful and moist.
Yi Sang'. I have done experiments and found that wheat-eating bugs breed much faster in farmland planted exclusively with wheat than in farmland planted with wheat mixed with other crops. If only one type of cereal is planted in a large area, it will cause problems.
The sharp increase in the number of certain insects provides conditions. Therefore, I believe that farming should be mainly based on wheat and grass, mixed with some peas, broad beans, mustard, green onions, chrysanthemums, white radish, etc., which can greatly reduce the occurrence of pests and diseases.
”.
This young man was serious and actually did an experiment, which Wang Tai needed to show admiration for.
"Wang Shangshu", Liang Shengwen bowed and called him softly, and then went to ask Chen Huan to come out to greet him.
"Shh", Wang Tai made a silencing gesture and whispered: "Don't talk, let Mr. Chen finish the lesson."
"Yes", Liang Shengwen could only listen respectfully.
"Third, the method of preventing natural enemies. All pests have natural enemies. By introducing natural enemies, pests can be prevented and controlled. Pests can be controlled with insects. "Southern Plants and Trees" records that 'the people of Jiaozhi wrap mats in mats and store yellow ants in their nests and sell them in
In the market, this ant can protect citrus trees in the south from being harmed by beetles (small insects). The insect-controlling performance of the yellow ant depends on the quantity, so it should be sold together with the nest. Birds can also be used to control insects. Qin people have observed woodpeckers.
It is a pest that eats forest trees. "The Biography of Southern History" also has records of birds eating locusts. It can also be used to treat insects. "Yuanhai Leihan" says, 'frogs can eat insects, so hunting must be prohibited'; poultry can also eat insects.
Yes, I once said to Huo Tao, 'There are crickets in Xiangshan, Panyu and other places in Guangdong, which eat the buds of grains and cause great harm to agriculture. Only ducks can eat them, and ducks do not harm rice fields.'"
"Sir", another farmer raised his hand and asked: "What you just said are all methods to prevent and control diseases and pests in the fields. I have a barn at home, and pests are often infested. How can I control it?"
"It doesn't matter, you can use mugwort hidden in earthenware or stoneware to repel insects," the young Confucian scholar said with a smile.
"I also have a method, you can use the grass to smoke out insects. The smoke fills the room and the storage pests are gone." Suddenly a loud voice came, but it was Wang Tai, the Minister of the Ministry of Agriculture, Forestry, Animal Husbandry and Fishery. Hearing this verse, he felt itchy and loud.
He added with a smile.
