Spring corn should be based on base fertilizer, supplemented by topdressing; farmyard manure is mainly supplemented by chemical fertilizer; nitrogen fertilizer is the main factor, phosphate fertilizer is the supplement; panicle fertilizer is the main principle, and granular fertilizer is the basic principle of fertilization.
The base fertilizer should generally account for about 70% of the total fertilization. Most of the phosphate fertilizer should also be combined with the base fertilizer, and it is generally applied in combination with autumn tillage in the previous year. When applying the base fertilizer, it should be evenly mixed with the soil. If nitrogen fertilizer is used as the base fertilizer, it must be applied deep to prevent nitrogen loss. In the phosphorus-deficient soil, 450-600 kg of fertilized calcium per hectare; in the potassium-deficient soil, 150 kg of potassium chloride per hectare; in the zinc-deficient soil, 15 kg of zinc sulphate per hectare is applied.
Fertilizer
Before the spring sowing, use a small amount of farmyard manure with a suitable amount of nitrogen, phosphate fertilizer or acupoint application as corn seed fertilizer.
top dressing
Spring corn topdressing adopts the “pre-light and heavy†fertilization method, that is, 1/3 of topdressing is applied before the jointing of the corn, 75-150 kg of urea per hectare, and 2/3 of topdressing is applied in the big bell mouth. Applying 150-300 kg of urea per hectare to meet the needs of nutrients in the spikelets, floret differentiation and grain formation stages of maize ears. The experimental results confirmed that the spring corn adopts the “pre-light and heavy†fertilization method, which is 13.3% higher than the “pre-weight and light†fertilization method.
