First, a reasonable rotation, dumping vegetables. Should avoid continuous cropping with similar vegetables, in order to reduce the source of diseases and insects, generally onions, garlic, wheat bran as well. Fallen vegetables can rationally utilize land nutrients, improve soil structure, and reduce pests and diseases. Second, select fine species and enhance resistance. To select good varieties with strong stress resistance, soak seeds in cold water for 10 minutes before sowing, then remove and soak in water at 50°C for 30 minutes. Third, timely sowing, a full seedlings. The normal normal sowing date begins on July 15-17, peaks on the 20th and ends on the 25th. When planting, it is necessary to plant seedlings and preserve seedlings. To this end, one must be meticulous in site preparation and the second is to rob and sow. For the land that is well-grounded and poorly-grounded, it is necessary to push out the dry soil and sow the seeds on the wet soil. If the ground hoe is not enough and the land surface is not good, it is necessary to carry water. The third is to do precise seeding. Each seed should be controlled within 5-6 grains, and no more than 6-7 grains. The cover soil should be consistent in depth and depth, usually about 1 cm. After sowing, timely repression, according to the severity of the weather may be, dry soil can be more heavy, wet soil can be more light. Fourth, rational fertilization, promote birth. Autumn cabbage needs to absorb a large amount of nitrogen, phosphorus, potassium and some trace elements during the birth process. How much fertilizer, depending on factors such as fertility, pre-planting, variety, etc., on the basis of applying base fertilizer, but also to top-dress three times, that is, raise seedling fertilizer, hair tree fertilizer, ball fertilizer, the principle of top dressing is nitrogen, phosphorus, potassium The combination of organic manure and bio-fertilizer meets the need for nutrients at different growth stages of Chinese cabbage. Fifth, strengthen management and win harvests. First, the seedlings and the seedlings were planted three times in total. The seedlings were first planted in the seedlings for the first time, leaving 3-4 seedlings in each seedling. The second seedlings were grown when the seedlings grew to 4-5 leaves, leaving 2 for each seedling. Trees; group time when the Dingmiao, leave a tree every time. The second is to achieve three planers and three pods, loose soil, drought protection, eliminate weeds. Third, scientific irrigation, in the growth period of autumn cabbage should be filled with water four times, first, cooling water, before the emergence of Dingmiao, Xiao Qin ground irrigation, can prevent poisoning; Second, Baomiao water, cabbage grow to 4-6 true leaves When it is time to set seedlings, timely irrigation, is conducive to the development of the root system; third is the water of the rosette, to see the wet see dry mainly to prevent root rot, beneficial seedlings, to prevent leggy; four is the heart of the water, the heart before the filling of a water , And then stop the water, irrigation once every 7-8 days, the late ball, stop irrigation about 10 days before harvest. The fourth is disease prevention and extermination, which mainly adopts biological measures such as Trichogramma beetle and Golden wasp to control. To prevent downy mildew and soft rot disease, the main selection of disease-resistant varieties, rational use of the wheel, timely drainage, and more spade. Excerpt from: Rural News
