The ideal fertilization method for applying a chemical fertilizer is to apply organic fertilizer first, then rationally mix nitrogen, phosphorus and potassium fertilizers and apply them scientifically.
Avoiding the extra-root fertilization at noon, the temperature is high at noon. Not only does the evaporation of liquid fertilizer not only evaporate quickly, but also it is not easy to be preserved on the surface of the crop, so it is difficult to be absorbed by the pores and lenticels quickly.
Avoid using nitrogen fertilizer on topsoil to apply nitrogen fertilizer to the shallow layer of topsoil. Nitrogen is easily decomposed and volatilized after being exposed to sunlight.
Avoid excessive application of high-concentration fertilizers at any time. Regardless of the type of fertilizer, if the amount of application is too large, the roots of the crop will be "back-sucked", causing damage to the roots.
Avoid applying phosphate fertilizer with water, potassium fertilizer is easy to be fixed, nitrogen fertilizer is easy to be volatile, and the fertilizer applied with water basically stays in the topsoil, and the fertilizer utilization rate is very low.
Avoid applying ammonia water and ammonium bicarbonate in the greenhouse or greenhouse. Because the ecological environment in the greenhouse is in a high temperature closed state, the two fertilizers are easily volatilized under high temperature and closed conditions, causing the plants to be smouldering and affecting normal growth.
It is unscientific to arbitrarily mix and apply without considering the nature of the fertilizer. If the ammonium nitrogen fertilizer is mixed with alkaline fertilizers such as grass ash, lime, and phosphate fertilizer, it will accelerate the volatilization of nitrogen, cause waste of fertilizer, and will also damage crops.
Avoid the application of phosphorus fertilizer, phosphorus in the soil is very small, the application is particularly easy to be adsorbed and fixed by the soil surface layer, greatly reducing the phosphorus fertilizer efficiency.
Avoid applying excessive nitrogen fertilizer to the roots of leguminous crops with leguminous bacteria. If the amount of nitrogen fertilizer is too much, it will directly affect the nitrogen fixation capacity of rhizobium.
Avoid applying excessive amounts of chlorinated fertilizer to sensitive crops. Tobacco, citrus, potato, and grapes are crops that are sensitive to fertilizers. Do not apply too much chlorine at one time, otherwise it will affect the normal growth of plants.
Avoid fertilizing before heavy rain. Because of heavy rain or showers after fertilization, fertilizer is easily washed away by rain, resulting in loss of nutrients.
Avoid micro-fertilizers such as zinc, molybdenum, boron and other micro-fertilizers can solve crop deficiency, but if you apply micro-fertilizer alone, it will cause crop malnutrition and growth and development will be blocked.
