The early stage of crop application in the seedling stage absorbs phosphorus the fastest, if the seedling stage is deficient in phosphorus, it will affect the later growth.
Fine application of superphosphate is easy to absorb moisture and agglomerate during storage. When applied, it is broken and sieved to facilitate root absorption.
Concentrated phosphorus application is easy to be fixed by iron, aluminum and calcium in the soil. Therefore, it should be applied at the point and strip, so that the phosphorus is fixed around the seeds and roots, which is beneficial to the root absorption of the crop.
Mixed with organic fertilizers, especially calcium, magnesium and phosphate fertilizers must be mixed with organic fertilizers to convert the insoluble phosphorus in the phosphate fertilizer into effective phosphorus that can be utilized by crops. Since the phosphate fertilizer is mixed in the organic fertilizer, the contact with the soil can be reduced, thereby improving the fertilizer efficiency of the phosphate fertilizer.
The layered phosphate fertilizer has little mobility in the soil, and it does not move where it is applied. Therefore, phosphate fertilizer is applied to both the bottom layer and the shallow layer.
Mixed application of nitrogen fertilizer and phosphorus fertilizer with nitrogen fertilizer can balance nutrients, promote the rooting of crop roots, and lay a foundation for high yield.
When the roots are sprayed on the crops to the late growth stage, the roots are aging, and the ability to absorb nutrients is weakened, often resulting in phosphorus deficiency. At this time, water-soluble calcium superphosphate can be sprayed on the leaves to allow phosphorus to enter the plant through the pores or stratum corneum of the foliage, cereals can be used at a concentration of 1% to 3%, and vegetables with a concentration of 1%. Spray on a sunny morning or evening.
Appropriate amount of phosphorus fertilizer can be used for a long time. It can be used for 2 to 3 crops at a time. Therefore, it is not necessary to apply phosphate fertilizer to every crop. Generally, it can be applied once every 1 to 2 years. At the same time, the appropriate dosage should be calculated according to the target yield and soil fertility of different crops, and the balance of nitrogen, phosphorus and potassium nutrients should be considered.
Phosphate fertilizer is applied to the soil, such as superphosphate is an acid fertilizer, suitable for neutral and alkaline soil application; and calcium magnesium phosphate fertilizer is best used in acidic soil.
Phosphate fertilizer is most suitable for crops that are particularly sensitive to phosphorus, and is mainly applied to beans, cotton, wheat, potatoes, and melons with good economic benefits. In addition, the phosphate fertilizer should be applied in a concentrated manner, and the dosage is small, but the effect is large.
Can not be mixed with alkaline fertilizer, plant ash, lime, etc. are alkaline substances, if used in combination, the effectiveness of phosphate fertilizer will be significantly reduced, which is not good for crop yield increase. Generally should be 7 to 10 days apart.
