Avoid noon at noon for high temperature at noon. The liquid fertilizer will not only evaporate quickly after being sprayed, but also it will not be well preserved in the body surface of the crop and it will be difficult to be absorbed by the stomata and lenticels soon.
Avoid applying nitrogenous fertilizer on topsoil to apply nitrogen fertilizer to shallow layers of topsoil. Nitrogen is easily decomposed and volatilized when exposed to sunlight.
Avoid excessive application of high-concentration fertilizers regardless of the type of fertilizer, if a large amount of application will make crop roots "back sucking" phenomenon, resulting in damage to the roots.
Avoid application of phosphate fertilizer with water, and potassium fertilizer is easily fixed. Nitrogen fertilizer is easy to volatilize. The fertilizer that is applied with water basically stays on topsoil, and the fertilizer utilization rate is very low.
Avoid application of ammonia and ammonium bicarbonate in greenhouses or greenhouses. Because the ecological environment in greenhouses is closed at high temperatures, the two fertilizers are easily volatilized at high temperatures and confined conditions, causing the plants to be smoked and affecting normal growth.
Avoid application of phosphorus fertilizer Phosphorus in the soil mobility is very small, particularly easy to spread the soil surface adsorption fixed, greatly reducing the fertilizer efficiency of phosphorus.
Avoid excessive application of chlorinated fertilizer to sensitive crops such as tobacco, citrus, potato, and grapes, which are sensitive to fertilizers. Never use too much chlorine at one time, otherwise it will affect the normal growth of plants.
Avoid fertilization before heavy rains. For example, if heavy rain or showers are encountered after fertilization, the fertilizer can easily be washed away by rain, resulting in the loss of nutrients.
Boiled micro-fertilizers such as zinc, molybdenum, boron and other micro-fertilizers can solve the problem of crop nutrient deficiency. However, if micro-fertilizer is applied alone, it will cause crop malnutrition and hinder growth and development.
