Avoid applying chemical fertilizers. The simple application of chemical fertilizers in rapeseed field results in poor soil consolidation and physical and chemical properties, and the production level of field is reduced. Both organic and inorganic fertilizers should be applied at the same time, and organic fertilizer accounts for more than 60% of the total. At the same time, the types of rapeseed fertilizer should be complete. Avoid enough fertilizer. According to the test, if the yield per mu is more than 100 kg per mu, 10 kg of pure nitrogen, 4 kg of phosphorus and 10 kg of potassium must be guaranteed per mu. Avoid point fertilizer. Point fertilizer application can easily cause excessive local fertilizer concentration, resulting in the root can not be uniformly absorbed, and even cause rape to burn roots, affecting growth, especially in the application of ammonium bicarbonate. Therefore, rapeseed fertilization is best applied in the ditch between rows of rape, generally 10 cm deep, 20 cm wide is appropriate. Bogey Miao Fei delay. It is often only 2 months after transplanting live plants in rapeseed, some farmyard manure is applied for seedling fertilizer. In fact, at this time rape is needed to absorb more nutrients from the field, and at this time if basic nutrition can not keep up, it will affect the growth of rape, and even cause "freezing seedlings." For this reason, when transplanting rapeseed, it is necessary to use dilute feces and urine to put rapeseed to set the root water; after living roots, use human excrement 5 to 10 to add urea 2 to 3 kg to water 20 to 30 tens to consolidate water. seedling. Do not ignore the use of boron fertilizer. Rape is more sensitive to boron fertilizers. Boron deficiency can cause physiological diseases, poor root development, and only flowering is not strong or the grain is not full. Generally 0.2 to 0.3 kg of borax is used as base fertilizer. At the same time, boron fertilizer was sprayed in the seedling stage, bud stage and flowering stage of rapeseed, and 50 kg of borax was used to spray 50 kg of water per mu.
