Economical application. After the application of phosphate fertilizer, the seasonal crop can only use a small part of it, and the aftereffect can last for several years. Therefore, it is not necessary to apply it every year for a few days after the application of phosphate fertilizer to avoid waste.
Early application. Crops absorb phosphorus at the seedling stage fastest, accounting for half of total phosphorus in the growing season. If phosphorus deficiency occurs during seedling stage, it will affect the later growth. Even if it is applied later, it is difficult to recover the loss of early phosphorus deficiency. phosphorus.
Finely applied. Calcium superphosphate is easy to absorb moisture and agglomerate during storage. When applied, it is broken and sieved to facilitate root absorption.
Concentrated application. Phosphorus is easily immobilized by iron, aluminum, calcium and other elements in the soil. Therefore, it should be applied to the acupoints and applied to make the phosphorus fixed, which is beneficial to the root absorption.
Mixed with organic fertilizer. Phosphate fertilizer, especially calcium magnesium phosphate fertilizer mixed with organic fertilizer, can convert the poorly soluble phosphorus in the phosphate fertilizer into the effective phosphorus which is easily absorbed by crops.
Layered application. Phosphate fertilizer has little mobility in the soil, and where it is applied is basically where it is. Therefore, phosphate fertilizer should be applied in both the deep and shallow layers. Applying the phosphate fertilizer to the shallow layer is conducive to the absorption of the seedlings, so that the crops turn back early and the tillers are fast. Generally, 20-40 kg of phosphate fertilizer per hectare, 1/3 of shallow layer and 2/3 of deep layer.
Mixed with nitrogen fertilizer. Crops absorb a certain proportion of nutrients, and if the proportion is out of balance, it will not grow well. Single application of nitrogen fertilizer, root system is not well developed, easy to fall, and susceptible to pests and diseases, and accelerate the excessive decomposition of nitrogen in the soil, causing imbalance of nitrogen and phosphorus. The combination of nitrogen and phosphorus can balance nutrients and promote root growth, laying a foundation for high yield.
Spray outside the roots. When the crops are in the late growth stage, the root system gradually ages, and the ability to absorb nutrients is weakened, often resulting in phosphorus deficiency. At this time, the water-soluble calcium superphosphate can be sprayed on the agricultural leaves to allow the phosphorus to enter the plant through the pores or stratum corneum of the foliage. For cereal crops, 1-3% phosphate fertilizer can be used, and vegetables can use 1% phosphate fertilizer. Spray on a sunny morning or evening.
Apply to phosphorus-deficient soil. Phosphate fertilizers in red soil dry fields, yellow mud fields, duck hoe fields, and cold-soaked fields have increased yields significantly. Fertilizer fields, loam soils, and fields that have been continuously applied with large amounts of phosphate fertilizer in previous years may be appropriately applied.
Improve the effect of phosphate fertilizer application
Apply on crops that are most sensitive to phosphorus reactions. These crops are beans, rapeseed, wheat, cotton, potato, melon, etc., and the application of phosphate fertilizer can obtain higher economic benefits.
