First, a reasonable rotation, planting vegetables. Should avoid continuous cropping with similar vegetables to reduce the source of the disease and the source of insects, generally with onions, garlic, wheat bran as well.
Inverted vegetables can make rational use of land nutrients, improve soil structure, and reduce pests and diseases.
Second, select excellent species to enhance resistance. To choose an excellent variety with strong resistance, soak the seeds in cold water for 10 minutes before sowing, then remove them and soak them in water at 50 °C for 30 minutes.
Third, timely sowing, one full seedling. The normal normal sowing date starts from July 15-17, peaks on the 20th, and basically ends on the 25th. A sowing seedling should be done at the time of sowing. To this end, one must carefully plan the land, and the second is to rush to sow. For the plots with good bottom and poor surface, it is necessary to push off the dry soil and sow the seeds on the wet soil. If the bottom is not enough, the surface is not good, and the water should be planted. Third, to do the precision sowing, each seed should be controlled in 5-6, the maximum can not exceed 6-7, the soil should be deep and shallow, generally about 1 cm. After the broadcast, timely suppression, light and heavy according to the grievances, the soil can be heavier, the soil can be lighter.
Fourth, rational fertilization, promote fertility. In the process of growth, autumn cabbage needs to absorb a large amount of nitrogen, phosphorus, potassium and some trace elements. According to the ground force, the front hoe, the variety and other factors, on the basis of the application of the bottom fertilizer, it is necessary to carry out three top dressings, namely, raising the seedling fertilizer, planting the fertilizer, and forming the ball fertilizer. The principle of topdressing is nitrogen, phosphorus and potassium. Combination, organic fertilizer and biological fertilizer combine to meet the needs of autumn cabbage in different growth stages.
Fifth, strengthen management and capture a bumper harvest. First, the seedlings and seedlings were planted three times in the morning. For the first time, the seedlings were grown in the seedlings, and the seedlings were 3-4 times per seedling. When the seedlings grew to 4-5 leaves, the second seedlings were carried out. The tree is fixed when the group is planted, and one tree is left for each group. The second is to make three planes and three rafts, loose the soil, resist drought and protect the weeds. The third is scientific irrigation. In the growth period of autumn cabbage, water should be poured four times. First, the water is cooled. Before the emergence of the seedlings, the seedlings are planted, and the small waters are used to prevent poisonous diseases. The second is to protect the seedling water. The cabbage grows to 4-6 true leaves. When the seedlings are planted, timely irrigation is beneficial to the development of the root system; the third is the rosette water, which is mainly wet and dry, to prevent root rot, which is beneficial to the seedlings and prevent the length of the seedlings; the fourth is the water in the heart, and the water is irrigated before the heart. Then stop the water, once every 7-8 days, the end of the ball, stop the irrigation about 10 days before the harvest. The fourth is to prevent diseases and eliminate pests, mainly taking biological measures such as Trichogramma and Golden wasps for prevention and treatment. To prevent downy mildew and soft rot, mainly choose resistant varieties, rational use, timely drainage, and more shovel.
