Three new technologies for improving fertilizer efficiency
1, with or without combination. Organic fertilizers are applied in combination with inorganic fertilizers. Farmyard fertilizer is called organic fertilizer. It has complete nutrients and lasting fertilizer effect. Chemical fertilizer is called inorganic fertilizer. It has a single nutrient, high content and quick effect. In the agricultural fertilization technology, organic fertilizer and inorganic fertilizer must be applied in combination to complement each other and increase fertilizer efficiency. Combining human and animal manure with ammonium chloride, superphosphate, and potassium chloride can increase the yield by 10%-15% compared to the single fertilizer. 2, formula fertilization. The application of nitrogen, phosphorus, potassium and trace elements is called formula fertilization. According to the experiment, the utilization rate of nitrogen was 30%-38% for single application of urea, while the utilization rate of nitrogen was increased to 58%-60% for formula application, and the utilization rate of single application of phosphate fertilizer and phosphorus pentoxide was 12%-14. %, for formula application, the utilization rate is increased to 35% -38%; the utilization rate of single application of potassium chloride is only 31% - 35%, the formula application, the utilization rate is increased to 57% -61%. 3, deep nitrogen fertilizer application. The deep application of nitrogen fertilizer can effectively prevent the loss of nutrients and increase the utilization of nitrogen. According to the test: ammonium bicarbonate application, nitrogen utilization rate is 28.6%, deep application, nitrogen utilization rate increased to 58.6%; urea application, nitrogen utilization rate is 42%, deep application, nitrogen utilization Increased to more than 80%, especially the application of ammonium bicarbonate, can easily cause crop burning and poisoning.
