Taiwan's 75 soybeans "six defenses" cultivation techniques

The variety is a mid-maturing variety, the growth period: 90-100 days in early spring, and 75-85 days in spring and summer. The beans are loose, brittle, strong and good taste. Plant height 60-80 cm, branching 4-6 branches, 6 compound leaves blossom, 9-10 compound leaves self-sealing. Mu density of 9000-10000 strains, 28 strains per plant, yield 700-900 kg per mu. Through years of cultivation, a set of "six preventions" cultivation techniques have been explored and are introduced as follows:
First, prevent exposure of seeds. The soybean has low fat content and high protein content. If the seeds are exposed, the seedling rate will be affected. Through comparative tests, the seedling emergence rate of the seeds was only 10%-20%, and the emergence rate of unexposed seeds was over 90%. When drying seeds, they must not be exposed to strong light. You can coat the seeds with a layer of white paper to increase the rate of emergence.
Second, prevent seeding. Taiwan's 75 soybeans are large in size and weak in the top soil. They need to be sown after soil preparation and are also conducive to increasing soil moisture content.
Third, anti-sowing too deep. Taiwan's 75 soybean seeds have low oil content, and the cotyledons are large when unearthed. If the seeds are sown in deep unfavorable cotyledons unearthed, tendon seedlings tend to form easily, and if they grow too long, they will rot. It is advisable to broadcast 3-4 cm deep.
Fourth, prevent pests and rats. Before sowing, 300-400 milliliters of phoxim emulsion was used to water 50-200 kilograms of water and poured on the sowing line to prevent underground pests. After sowing, the field mice were hunted with chemicals. Taiwan's 75 soybean susceptibility virus disease, the incidence of heavy blocks even cut production. Viral disease is transmitted through locusts. Attention should be paid to the control of locusts. When the cotyledon is spread flat, the mu is sprayed with 800-1000 times of virus emulsion, and 7 days after spraying, it can reduce the diseased plant rate.
Fifth, to prevent flowering and podging period of high temperature. Flowering and podging period encounters high temperatures, and it is often easy to cause flowering without pods and flowers falling off. When calves are exposed to high temperatures, paralysis can increase. The sowing date of wheat cultivar in our city is from the 25th of May, and the symbiotic period of wheat and beans is 20 days. If it grows too long, it will form a tall plant. Late planting is vulnerable to high temperatures above 37°C. If the flowering and podging period meets high temperature and drought, we can use furrow irrigation to reduce the humidity in the field and improve the microclimate in the field.
6, lack of anti-fertilizing. The soybean needs a large amount of fertilizer, the base fertilizer Mushi compound fertilizer 15 kilograms, full-layer application; leaf age 3.5 pieces of compound leaves, Mushi compound fertilizer 10 kg, 200 kg of rare human feces, urea 10 kg, early flowering Mushi compound fertilizer 15 kilograms, 10 kilograms of urea, 10 kilograms of potash, and 5 kilograms of urea in the grain expansion period. During the clams, 0.2% potassium dihydrogen phosphate is sprayed outside the roots every 7 days to prevent premature aging.
