Rapeseed strong seedlings are good for autumn and winter, which is beneficial to the future transformation of each growth stage. Therefore, rape seedling fertilization should grasp the following points:

First, apply base fertilizer. Generally, 1000-1500 kg of compost and 20-25 kg of phosphate fertilizer are used per acre. After mixing, the soil is mixed into the topsoil and mixed with 1500-2000 kg of manure water. The appropriate amount of chemical nitrogen fertilizer is applied to the seedbed soil. , Fertilizer bed soil.

Second, early Shi Qi Miao Fei. When 80% of the seedlings are planted, the thin manure and urine water and fertilizer per acre will be about 750 kilograms, or about 4 kilograms of urea will be poured into the water to prevent the growth of the rape seedlings after 3 to 4 leaf stages, and the leaves will turn red. If the foot is sufficiently fat and the seedlings grow vigorously, it is not suitable to top-dress, and the seedlings shall be cultivated in the 4th to the 5th leaf stages to prevent prosperous growth and the formation of tall seedlings.

Third, increase the application of phosphorus and potassium fertilizers. Phosphorus and Potassium fertilizers in basal fertilizers are not applied or the soil lacks phosphorus, potassium, and phosphorus elements. During the seedling stage, more attention should be paid to the application of P and K fertilizers. In general, the application of superphosphate is 15~20kg, or calcium magnesium phosphate is 20~25kg. Phosphate fertilizer applied to seedbed can be applied without applying phosphate fertilizer, but 0.2% potassium dihydrogen phosphate can be sprayed on the foliar. Potassium or potassium sulphate is poured before the three-leaf stage of seedlings.

Fourth, suitable for fixed seedling fertilizer. Before and after the seedlings are sown, 500 to 750 kilograms of thin human and animal manure water is applied for 2 to 3 times. Soil drought, thin and thin can be more appropriate to apply some of the soil wet seedlings can be less applied. In the 4th to 5th leaf stage, the main control was to stop the fertilization and watering and to carry out the seedlings to prevent leggy phenomenon in the seedbed stage.

Five, Qiao Shi got up fat. A small amount of nitrogen fertilizer is applied 5~7 days before transplanting, and 7.5~10 kg of ammonium bicarbonate per acre can be used to dilute. If the leaf color of rapeseed seedlings is lighter, or when old red leaves appear, spray fertilizers can be used in combination. Normally, 1 to 1.5 kg of superphosphate is used. After soaking with 10 kg of fresh water for a day and night, the filter solution should be properly added with fresh water.

Six, make-up Borax fertilizer. The demand for boron in rapeseed is high and very sensitive during the whole life period. Boron deficiency will not only cause flowering in the later stage of rape, but also have a great impact on the seedling stage. Therefore, in the seedling stage, 0.5 kg of borax can be mixed with the topdressing fertilizer to pour water. If the symptoms of boron deficiency occur at this time, 0.1%~0.2% of the borax fertilizer solution is used for 50 kg to spray the leaves. Promote the leaves to normal, the effect is obvious.
