Chinese cabbage is green vegetables and cabbage. Of course, in some places, these are known as their own vegetable varieties. Cabbage is actually a cold-tolerant vegetable, and it likes a cool climate. In the autumn and winter seasons in South China, it is especially suitable for the growth of Chinese cabbage. In order to obtain high yield, these managements in the autumn and winter are very important. First, select stable varieties with high yield, high yield and good quality. Such as short-legged black leaves, 17th cabbage, milk cabbage, etc. for autumn and winter cultivation. Second, timely sowing, cultivating strong seedlings Autumn and winter cabbage can be sown from August to January, and is most suitable from September to October. Seedling transplanting is generally used. You should choose loam that retains water and protects fertilizer and drains well to nurse nursery. Before harvesting, the crops should be ploughed and dried in the morning, cleaned in the pasture, and applied to the base fertilizer. Each mu of nursery nurses will use 1000-1500 kg of decomposed pig cow dung and 10-15 kg of superphosphate as base fertilizer. After the land preparation, it will be built into a sorghum, which is 1.5-2 meters wide. Planting 0.75-1 kg per mu of seedbed, 8-10 mu of field can be planted after seedlings. When planting, you should master the sowing and proper dilution, and after the emergence of the seedlings, you should prevent the length of the seedlings. Generally, the seedlings are 2-3 times, and the seedlings should be topdressed and watered in time to promote the healthy growth of the seedlings. Under normal circumstances, the field can be transplanted 25-30 days after sowing. Third, apply enough base fertilizer, reasonable close planting Cabbage with green leaves as the product, the growth period is short, to obtain high yield, the first should be applied to the base fertilizer, generally 1000 kg per mu of decomposed pig cow dung, 10 kg of nitrogen, phosphorus and potassium compound fertilizer as base fertilizer, and soil after fertilization Mix well. The planting density of Chinese cabbage in autumn and winter varies according to variety, soil and climatic conditions. The spacing of most varieties is 20-25 cm square. Fourth, strengthen the management of fertilizer and water, promote high quality and high yield The root group of Chinese cabbage is shallowly distributed, and its absorption capacity is low. During the growth period, sufficient fertilizer and water should be continuously supplied, and the quick-acting nitrogen fertilizer should be applied several times to obtain high quality and high yield. After the seedlings are planted, the root water should be poured immediately, and then watered once a day to promote the rapid growth of the seedlings and restore growth. Post-watering should be based on the weather, usually combined with fertilization. When the seedlings are planted and the new roots are grown, 15% of the manure is used to topdress once. After every 5-7 days, the manure and manure will be applied once, and the concentration will gradually increase to 40%. The whole season was topdressed 4-6 times, and the fertilization was stopped 8-10 days before harvesting. At the same time, the amount and concentration of fertilizer should be flexibly controlled according to the weather conditions. In the south wind days, the damp and hot weather is not conducive to the growth of cabbage, and the amount of fertilizer should be less or less. North wind days, sunny days, cold weather with large temperature difference between day and night, cabbage grows fast, fertilization can be more concentrated. In addition, in the vigorous growth period of cabbage leaves, the foliage can be sprayed with 0.7-0.8% urea solution on sunny days to carry out the top dressing, which can obviously promote the growth of the leaves, which can deepen the color of the leaves and improve the quality. The above is the key measures for the cultivation of Chinese cabbage in autumn and winter. Apart from these four points, do you have any other supplements for your friends?
