Fertilizer application is good

Deep application of bottom fertilizer: There are two methods for deep application of bottom fertilizer: one is to first plow and then to plow; the other is to apply fertilizer to the furrow. The second method is better. The depth of fertilization is required to be 6 cm, the width of the fertilizer belt is 3 to 5 cm, and the fertilizer is evenly continuous without obvious broken strips. Deep application of seed fertilizer, when the application of deep fertilizer is required, a certain thickness can be formed between the seed and the fertilizer, generally more than 3 cm, to meet the nutrient requirement of the growth of the crop seedling, and the occurrence of burning and burning can be avoided.
Deep application of top dressing: deep application of top dressing is between 10 and 20 cm on both sides of the crop line. The method of opening small ditch or hole is adopted. The depth is 6-10 cm, the fertilizer bandwidth is more than 3 cm, and the soil is covered after fertilization. .
