    According to the characteristics of each growth period of rapeseed, 15-17kg of pure nitrogen, 1 phosphorus pentoxide and potassium oxide are generally used per mu; Among them, nitrogen fertilizer accounts for 50% of base fertilizer, seedling fertilizer accounts for 30%, moss fertilizer accounts for 20%, and phosphate fertilizer and potassium fertilizer plus borax are applied as base fertilizer. The base fertilizer is mainly organic fertilizer, which is generally inOn the basis of 3000kg of organic fertilizer per mu, 15-20 kg of urea or 30kg of ammonium carbonate, 10-15kg of diammonium phosphate or 30-40kg of calcium phosphate and boron fertilizer are applied.

    Early application of seedling fertilizer Due to the long seedling period and large amount of fertilizer absorption of rapeseed, seedling fertilizer must be applied in advance to promote the growth of rape before winter and ensure safe wintering. Seedling fertilizer is generally followed after transplanting rapeseed live trees or in the five- to six-leaf stage of direct seeding rapeseed"Early, fast, light"The principle of post-application. When flowering and poding, when the soil is deficient in potassium, spray once at the first flowering stage, and do not shade.

    Rape Honda boron. The root system of rape has a strong ability to absorb phosphorus. The amount of phosphate fertilizer is generally 20-30 kg of superphosphate or calcium-magnesium phosphate fertilizer per mu, but the reaction is sensitive.

    Rapeseed flowering fertilization, rape flowering period is longer than the general plant flowering period, flowering pod period, flowering period can be as long as about 30 days, this period of nutrient consumption and transformation is the largest, so in the flowering period of water and fertilizer should be timely, topdressing time should be appropriately advanced to the bud stage of use, farm fertilizer nutrients are sufficient, in addition to containing common nitrogen, phosphorus, potassium elements, but also contains rapeseed growth necessary boron, sulfur, zinc and other trace elements, the application of farm fertilizer can effectively prevent rape from deficiency phenomenon.

    Rapeseed planting, the most fertilizer is still nitrogen-containing, phosphorus-containing and potassium-containing fertilizer, if one of them is missing, rape can not grow normally, there will be such and such nutrient deficiency symptoms, at the same time in the growth process, especially emphasize that although rape seedling stage does not need boron, but this is the most sensitive period of boron in rape's life. If boron deficiency occurs at the seedling stage, it is susceptible to hunger and thirst and brings the hidden danger of flowering but not fruiting, even if boron fertilizer is applied during flowering.

    Rapeseed has strong adaptability to soil, but prefers loose, fertile, high organic matter content, and strong water and fertilizer retention. The absorption of nitrogen, phosphorus and potassium by rapeseed is greater than that of nitrogen and greater than that of potassium. For every 1000 kg of rapeseed produced, it needs to absorb kilograms of pure nitrogen, phosphorus (P2O5) kilograms, and potassium (K2O) kilograms.

    Deficiencies in the trace element boron can cause boron deficiency. Individual plants absorb less nutrients; However, it reaches tens of thousands of plants per mu, so the plants in the group per unit area absorb more nutrients. The nutrient demand of rape is synchronized with the growth of plants, and the growth of plants in the early stage of growth is small, and the absorption of nutrients is also small. When the plant enters the vigorous growth period, the uptake of nutrients increases.

    This period, especially nitrogen, is related to the yield and quality of rapeseed, if the nitrogen is insufficient, the leaves become smaller, yellow, and the eating rate is low, therefore, in the facility cultivation to increase the application of basal fertilizer, improve the soil environmental conditions, conducive to root absorption, timely topdressing of nitrogen and potassium fertilizer, transplantation of slow seedlings after topdressing a small amount of nitrogen fertilizer, into the vigorous growth period, the amount of available nitrogen and potassium fertilizer topdressing should be increased, phosphate fertilizer for basal fertilizer.

    1. Farm fertilizer has sufficient nutrients, in addition to containing common nitrogen, phosphorus and potassium elements, it also contains trace elements such as boron, sulfur and zinc necessary for the growth of rapeseed.

    2. The fertilizer effect of farmhouse fertilizer lasts for a long time, and a fertilization can maintain the fertilizer effect for several months, which can reduce the possibility of fertilizer deficiency.

    3. The fertilizer efficiency of farmhouse fertilizer is slow, which will not increase the nutrient concentration in the soil rapidly, and it is not easy to make the newly planted rapeseed appear to burn seedlings.

    4. Farmhouse fertilizer has the effect of loosening the soil and enhancing the air permeability of the soil, which is not only conducive to the growth and development of rapeseed roots, but also not easy to make the soil compact.

    1. Balanced application of nitrogen, phosphorus and potassium fertilizers, mainly to adjust the amount of nitrogen fertilizers and increase the application of phosphorus and potassium fertilizers.

    2. Supplement boron fertilizer according to the available boron status of the soil.

    3. Increase the application of organic fertilizer, advocate the use of organic and inorganic and straw returning to the field.

    Abstract Dear, hello.

    Nitrogen fertilizers can be applied, as well as urea fertilizers, or nitrogen, phosphorus and potassium compound fertilizers.

    1. Nitrogen fertilizer is the key fertilizer for seedlings to grow, and the application of nitrogen fertilizer is helpful for rapeseed seedlings.

    2. The available nitrogen content in urea is high, and sufficient nitrogen is conducive to the formation of chlorophyll in rapeseed, which can lay the foundation for the life activities of rapeseed.

    3.Nitrogen, phosphorus and potassium compound fertilizer contains sufficient nitrogen, phosphorus and potassium elements, and a variety of elements are applied, and each element performs its own duties, so that rape can grow better and more vigorously.

    4.The nitrogen fertilizer in the nitrogen, phosphorus and potassium compound fertilizer helps the rapeseed to sprout, differentiate, and make the rapeseed plant grow stronger.

    5.The potassium fertilizer in the nitrogen, phosphorus and potassium compound fertilizer can promote the formation of stalks and branches, increase the number of pods, and reduce the possibility of sclerotinia sclerotinia in rapeseed.

    6.The fertilizer effect of urea is stable and long-lasting, and the effect of top dressing is obvious.

    7.Urea is an organic nitrogen fertilizer. Less damage to the soil and the environment.
