1 Shima fertilizer can keep warm and apply cold fertilizer with more potassium and potassium fertilizer, can increase the ground temperature by 2--3 °C, can increase the potassium content of plant cells, enhance the water holding capacity of cells, and make plants difficult at low temperature. freeze. In addition, the concentration of salt in the soil solution can be increased to reduce the damage degree of the roots of the rapeseed.
2 Schlain fertilizer can promote the growth and development of rapeseed buds. The rapeseed buds are the two periods of vegetative growth and reproductive growth. This period is the period in which rapeseed absorbs the most nitrogen and potassium nutrients. The application of wax fertilizer can ensure the phosphorus and potassium nutrients in this period. The supply promotes an increase in the number of effective branches and pods.
3 Spring use of rapeseed The flowering and maturity stages of rapeseed are the most vigorous period of reproductive growth. The phosphorus uptake 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 rapidly and the humidity is high. If the quick-acting fertilizer is applied, the plant will grow wild, causing lodging and disease. The application of organic fertilizer-based wax fertilizer, energy sources continue to release nutrients, to supply the needs of the late growth and development of rapeseed, thereby promoting the purpose of rapeseed to achieve spring stability.
The application rate of wax fertilizer depends on the condition of the seedling, the seedling is good, and the application of coarse fertilizer is mainly based on heat preservation: if the seedling is poor, more fertilizer is applied to supply nutrients.
Generally, the soil is 1200-1500 kg per mu. Or decomposed pig cow manure 700-800 kg, or fire ash 900--1000 kg, with phosphate fertilizer 10-15 kg. For rapeseed that is prematurely yellowed due to lack of nitrogen, about 400 kilograms of manure and 5-6 kilograms of urea per mu are applied. The application time of the fertilizer should be determined by the fertilizer due to the seedlings. The larger soil fertilizer and the pig and cow dung must be applied early, and must be applied when the field is convenient for operation before the rape is sealed. The quick-acting chemical fertilizer or human excrement applied to the water is generally applied from the winter solstice to the small cold. Fertilization must be combined with cultivating soil and plastic roots, and the fertilizer should be cooked into the soil.
