Whether combined with organic fertilizer and inorganic fertilizer application. Farmyard fertilizer is called organic fertilizer. It has complete nutrients and long-lasting fertilizer effect. Chemical fertilizer is called inorganic fertilizer. It has a single nutrient, high content, and quick results. 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 production by 10% to 15% compared with single fertilizer. Formula fertilization will be combined with nitrogen, phosphorus, potassium and trace elements, called formula fertilization. According to the experiment, the single utilization of urea, nitrogen utilization rate of 30% to 38%, while the formula application, nitrogen utilization increased by 58% to 60%; single application of phosphate fertilizer, phosphorus pentoxide utilization rate of 12% to 14% Formula application, utilization increased by 35% to 38%; single application of potassium chloride utilization of only 31% to 35%, formula application, the utilization rate increased by 57% to 61%. Deep application of nitrogen fertilizer with nitrogen fertilizer can effectively prevent nutrient loss and increase nitrogen utilization rate. 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. Centralized application of limited fertilizers is preferentially applied to low-yielding fields. According to the experiment, the same amount of 5 kg urea and potassium chloride are applied to three types of fields: high-yielding fields, middle-yielding fields, and low-yielding fields. The effect of increasing production varies greatly. On average, each kilogram of urea is applied, and high-yield fields increase rice production 3.5. In kilograms, middle-income fields increased rice production by 5.8 kg, and low-yielding fields increased rice production by 8.8 kg. 8kw High Frequnecy Welding Machine Product categories of 8Kw High Frequnecy Welding Machine, we are specialized manufacturers from China, High Frequency Embossing For Car Mat, High Frequency Embossing Equipment suppliers/factory, wholesale high-quality machine of high frequency welding R & D and manufacturing, we have the perfect after-sales service and technical support.
