First, the local fertilization should focus on the distribution of phosphate fertilizer in low organic matter and phosphorus-deficient soil in order to fully play the fertilizer shovel. Phosphate fertilizers are preferentially applied to slender thin fields, dry lands, new depressions, and raw land because these fields are usually less phosphorus-deficient. According to experiments on wheat, NPK combined application increased production by 16.5% compared with single application of phosphorus, 10.5% more than single application of nitrogen, and 6.4% more than combined application of nitrogen and phosphorus. Third, the mixed application of phosphate fertilizers and organic fertilizers can reduce the adsorption and fixation of phosphorus on the soil, promote the release of insoluble phosphates, and help increase the phosphate fertilizer efficiency. 4. Different phosphorus-enhanced crops have different phosphorus demand and absorption and utilization abilities. Practice has proved that legumes, rapeseeds, cotton, melons, and fruit trees are phosphorus-loving crops, and the application of phosphate fertilizer has a good fertilizer effect. Fifth, the critical period of appropriate application of crop phosphorus nutrition is generally in the pre-fertility period, the application of this period can maximize efficiency. Therefore, phosphate fertilizer should be used as basic fertilizer, seed fertilizer, paddy field and seedbed fertilization, root picking and early fertilizer. Six, concentrated application of phosphate fertilizer is easily fixed by the soil, the utilization rate is only 10-25% in the season, especially in a variety of clay soil, if applied phosphate fertilizer, can not fully play fertilizer effect. By adopting centralized fertilization methods such as furrow application, acupoint application, seed dressing and barnyardgrass, the application of P fertilizer to root-dense soil layers can reduce the contact surface between P fertilizer and soil, reduce the fixation of P by soil, and increase the utilization rate. VII. The application of foliar spray of superphosphate spray to the roots can make the leaves replace roots to absorb nutrients, synthesize organic matter, reduce the absorption and operation process, and has the characteristics of less fertilizer, rapid fertilizer efficiency and high utilization rate. The spraying time is better when the booting and filling stages are sprayed once. The amount of phosphorus sprayed outside the root can be 2-3 kilograms per mu, and the spray concentration should be 3-6%. Eight, with the application of micro-fertilizer in the reasonable application of phosphorus at the same time, in wheat, per gram of land allocated 1 kg of zinc fertilizer, boron 0.5 kg, the effect of increasing production is better. Nine, although the utilization rate of phosphate fertilizer in the economy is low in the season, its aftereffect is very long. The over-utilization efficiency of residual fertilizer in the 20-year period is 38.9%. Therefore, when phosphate fertilizer is used more often, it is not necessary to apply it every year, but it should be noted that each time The amount should not be too much to avoid wastage.
