Early application of phosphate fertilizer as base fertilizer should be applied early, because the key period of crop phosphorus requirement is seedling stage. Phosphorus is not deficient in the seedling stage, and there is little phosphorus deficiency in the middle and late stages of crop growth. Therefore, phosphate fertilizer has a good effect on the base fertilizer.
When mixed phosphorus fertilizer is mixed with high-quality manure or heap organic fertilizer, the poorly soluble substances in the phosphate fertilizer can be converted into effective phosphorus that can be utilized by the crop. At the same time, the soil is reduced due to the accumulation of phosphate fertilizer and organic fertilizer. Direct contact can reduce the fixation of phosphorus and improve fertilizer efficiency.
It is not advisable to apply single phosphate fertilizer alone, preferably in combination with nitrogen fertilizer. The effect of increasing the yield and production of nitrogen, phosphorus and potassium is better than that of single application. Generally, the ratio of nitrogen, phosphorus and potassium is 1:0.4:1.2. The application of phosphorus fertilizer is good for a good amount. The tube is 2 to 3 inches, so it is not necessary to apply phosphate fertilizer to every crop. Generally, it can be applied once every 1-2 years. At the same time, the appropriate amount should be calculated according to the target yield and soil fertility of different crops, and the balance of nitrogen, phosphorus and potassium should be considered.
Before and after flowering, the root-dressing crops were treated with superphosphate before and after flowering. The roots were aging during the late growth stage, and the nutrient abilities were weakened, which often caused de-fertilization. The spraying effect of water-soluble phosphate fertilizer was very good, and the spraying concentration was 0.5-2%. Time should be morning or evening.
Phosphorus fertilizer, that is, superphosphate is an acid fertilizer, suitable for neutral and alkaline soil application. Calcium, magnesium and phosphorus are best used in acidic soils.
Phosphate fertilizer is most suitable for crops that are particularly sensitive to phosphorus, and is mainly applied to beans, cotton, wheat, potato, and melons, with good economic benefits. In addition, the phosphate fertilizer should be applied in a concentrated manner. It is precisely this meaning that “a large piece of fertilizer is applied, which is not as good as a long lineâ€. The dosage is small and the effect is large.
Can not be mixed with alkaline fertilizers, such as grass ash, lime, etc. are strong alkaline substances, if mixed application, the effectiveness of phosphate fertilizer will be significantly reduced, the increase in phosphorus production and profit, generally should be staggered 7-10 days.
