Winter cabbage cultivation attention?
1. Planting on the ground, rational rotation, timely removal of the residues of the former crops, ploughing the sun as soon as possible, cleaning the pasture, deep-cultivating the fields, watering and protecting the soil, applying sufficient base fertilizer; seeding with new high-fat membrane after seeding, timely sowing Appropriate amount of sowing, and use the gums to gently lick the topsoil so that the seeds are sown into the soil.
2, seedling management, emergence of seedlings, should be in the cotyledon, Lacrosse, 3 ~ 4 leaf stage of the seedlings, seedlings, seedlings should be timely watering, topdressing (pay attention to nitrogen fertilizer content), to prevent the roots of the seedlings shaking Wilted. Spraying new high-fat film and photosynthetic nutrient film fertilizer at the right time can effectively prevent the infection of pathogens, improve the ability to resist natural disasters, increase the intensity of photosynthesis, and make the seedlings grow healthily.
3, transplanting and planting, before transplanting Datian should be watered, apply enough base fertilizer (1000 kg per mu of decomposed pig cow dung, pay attention to balance nitrogen, phosphorus, potassium in the soil), timely transplant, reasonable close planting, after planting Immediately watering, and spraying the new high-fat film 800 times liquid in time (effectively preventing the water from evaporating on the ground, not transpiration of the seedlings, shortening the slow seedling period, allowing the seedlings to quickly adapt to the new environment), then pouring water once a day in the morning and evening, continuously 3 to 4 days.
4. Scientific field management, after the end of the slow seedling period, timely tillage, watering and topdressing (15-20 kg of compound fertilizer applied to the acre, 15-20 kg of urea in the rosette period, 10-15 kg of superphosphate) ), and with the application of new high-fat film 800 times liquid to improve the utilization rate of fertilizer; spraying the strong stems in the rosette period of Chinese cabbage can make the stems of the plants thick, the leaves are thick, the leaves are fresh, the plants are flourishing, and the natural taste is strong. At the same time, it can improve the ability to resist disasters, reduce the amount of pesticides and fertilizers, and reduce residual poisons.
5, disease prevention, disease prevention and treatment is best to take prevention, can spray a new high-lipid film 600 times liquid, can form a polymer film on the growth surface of cabbage. It can keep warm, moisturize, prevent disease and deworm. Filter plant respiratory impurities, prevent pollution, and inhibit viral infection.
