The application of wax fertilizer in rapeseed is an important measure to increase production. Its role is mainly reflected in the following three aspects: Insulation and antifreeze. The application of fertilizers with more phosphorus and potassium as fertilizer can increase the ground temperature by 2 to 3 °C, increase the potassium content of the plant cells, enhance the water holding capacity of the cells, and make the plants not easy to freeze at low temperatures and avoid freezing damage. In addition, organic fertilizer and new high-fat membranes are added to reduce the damage of rapeseed roots. The wax is used in spring. The flowering and maturity stages of rapeseed are the most vigorous period of reproductive growth. The absorption of phosphorus reaches a peak, accounting for about 60% of the whole growth period, and also absorbs a certain amount of nitrogen and potassium nutrition. In the spring, the temperature rises quickly and the humidity is high. If the quick-acting fertilizer is applied, the plant will grow wild and cause lodging and disease. However, the application of organic fertilizer as the main fertilizer in combination with the vegetable Zhuanglingling, the energy source continuously releases nutrients, and supplies the late growth and development of the rapeseed, thereby achieving the purpose of stable spring rape. The application rate of wax fertilizer is determined by the condition of the seedlings. The seedlings are good, and the application of coarse fertilizer is mainly based on heat preservation. If the seedlings are poor, more fertilizer is applied to supply nutrients. Generally, 1200 to 1500 kg of soil-fertilized fertilizer per acre or 700-800 kg of decomposed pig cow manure, and 10 to 15 kg of superphosphate. For rapeseed which is prematurely yellowed due to lack of nitrogen, 400 kg of manure and 5 to 6 kg of urea are applied per mu. The application time of the wax fertilizer should be determined by the fertilizer due to the seedlings. The larger soil fertilizer and the early application of the pig cow manure must be applied before the rapeseed is sealed and the field is easy to operate. The quick-acting chemical fertilizer or human excrement applied with water is generally applied from the winter solstice to the small cold. Fertilization must be combined with cultivating soil and roots to bury the fertilizer in the soil. Disclaimer: Some articles on this website are transferred from the Internet.
