In winter, the temperature is low, the rainfall is small, and the soil is dry. We must use targeted fertilizers and adopt the correct fertilization method to ensure that the fertilization is economically effective. Pay attention to the use of fertilizer fertilizer. With low winter temperatures and weakened microbial activity, the fertilizers that need to be converted have a slower effect, and winter sowing of crops requires adequate fertilizers. The solution to this problem is to catch up with available fertilizers. Nitrogen fertilizer can use ammonium bicarbonate; Phosphorus fertilizer should use superphosphate as possible; Potassium fertilizer can use potassium chloride (but potato and tomato and other chlorine crops should use potassium sulfate in the late growth stage); 45% can be used for compound fertilizer. Compound fertilizer; farmyard manure available for human fecal urine. This is because, compared with urea, ammonium bicarbonate belongs to ammonium nitrogen fertilizer and can be directly absorbed and utilized by crops after being applied to soil, unlike urea (which belongs to ammonium ammonium fertilizer and needs to be urease-reduced by urea bacteria in soil. Transformation into ammonium nitrogen can only be absorbed by the root system.) Low temperature affects fertilizer efficiency and affects crop growth. Superphosphate contains 14%-20% of effective phosphorus pentoxide (80%-95% of which is soluble in water). It is a water-soluble, quick-acting phosphate fertilizer. Its fertilizer efficiency is faster than that of calcium magnesium phosphate fertilizer. However, it should be noted that greenhouse vegetable is best not to use ammonium bicarbonate, but instead use 45% three-component fertilizer to prevent ammonia damage. Phosphorus is easily absorbed by the soil and fails to solidify. When used as top dressing, superphosphate soaking liquid (5%-10% concentration) may be used or concentrated in the root-dense soil layer in the early stage of the crop. Cruciferous crops pay attention to the application of boron fertilizer. In winter crops, cruciferous crops account for a large proportion, such as cabbage, cabbage, radish, rape, etc. These crops are particularly sensitive to boron. At the same time, celery, wheat, carrots, etc. are also more sensitive to boron. Boron deficiency is not only seriously affected reproductive growth, but also blocked vegetative growth, decreased cold resistance, but also easy to induce heart rot. Application method: 1 The basal fertilizer boron fertilizer has the best effect on the medium or severely deficient boron soil; 0.5-0.75 kg borax can be used per acre to mix with dry fine soil or organic fertilizer, and then the ditch can be applied or applied. Or with nitrogen, phosphorus, potassium and other fertilizers together after the basic application; should not make the boron fertilizer directly contact the seeds (live) or seedlings (transplantation), so as not to affect the germination, emergence and growth of young roots, seedlings; should not be deep or The application amount should not be too large; if the application of borax exceeds 2.5 kg per acre, it will reduce the emergence rate and even reduce the production of dead seedlings. 2 The seed soaking should be treated with borax or boric acid. Usually, the borax is dissolved with hot water at 40°C; add borax or boric acid solution diluted with cold water to 0.01%-0.03%; pour the seeds into the solution and soak for 6-8 hours. The seed and liquid ratio is 1:1, and the seeds can be sown after drying out. 3 top-dressing (foliar spraying) with 0.1%-0.25% borax or boric acid solution, spraying 40-80 kg solution per acre each time; 6-7 days, spraying 2-3 times; leaf surface Spraying in the afternoon is good, spray to the foliage covered with droplets of degree; if the rain within 6 hours after spraying, should be re-spray 1 times. Pay attention to the application of wax fertilizer before the low temperature application of wax fertilizer, can increase the ground temperature 2 °C -3 °C, and increase the potassium content of crop cells, thereby increasing the cell's water holding capacity, so that the cells are not easy to freeze at low temperatures, enhance the ability of cold resistance; Fertilizers must vary from crop to crop. Rape should be mixed with manure and phosphorus to make it rot. Each mus of field should be applied to the rapeseed between 1500 kg or so, combined with earthworms, and be used from late December to early January. Early-maturing rape varieties due to early spring, Should be applied earlier than late-ripening rapeseed varieties; wheat should be applied in mid-to-late December, and strong miscellaneous fertilizers should be applied to strong seedlings, and weak-seedling and late-maturing wheat should be mixed with appropriate amount of phosphate fertilizer in soil-based miscellaneous fertilizers. Apply about 2,500 kilograms of soil and manure per acre of Datian farmland. The amount of perennial crops of fertilisers should account for 50% of the annual fertilization amount, 5000 kilograms of soil fertiliser per acre field and 2,500 kilograms of pig and cow manure. Apply after frost as snow. Greenhouses and vegetables to prevent nitrate accumulation A large number of nitrate itself is not harmful, but easily converted to nitrite, nitrite easily replace the human blood in the iron, causing blood poisoning. Nitrite and amines combine to form a strong carcinogen, nitrosamines, causing cancers such as stomach and intestines. In winter, there are more low-temperature and low-light weather conditions, greenhouse vegetables are more likely to cause a large accumulation of nitrate, especially leafy vegetables and root vegetables, in particular. Strictly control the amount of nitrogen fertilizer, increase the application of phosphorus and potassium fertilizers, in particular, can not apply ammonium nitrate, potassium nitrate and other nitrate nitrogen fertilizer.
