The dehydration type of fertilizer is mainly caused by excessive application of chemical fertilizer at one time, or insufficient soil moisture. After fertilization, the concentration of fertilizer solution in the soil is too large, causing reverse osmosis of water in crop cells, resulting in dehydration of crops. The plants that are affected by the fertilizer show wilting, and they seem to be affected by frost or boiling water. Lightness affects growth and development, and the whole plant died. Prevention: Each application should not be too large, and it can be applied with water when it is dry.
The smog-type fertilizer is mainly applied with ammonia, ammonium bicarbonate and other fertilizers. Such fertilizers are applied at high temperatures, which are prone to produce a large amount of ammonia gas, causing damage to crops, and lighter yellowing of the lower tip, affecting growth and development. The heavy ones caused the whole plant to die. Prevention: This type of fertilizer should be avoided at high temperatures.
Burning seed type fertilizer application of fertilizer is too large, or with ferric calcium phosphate, ammonium bicarbonate, urea, lime nitrogen and other chemical fertilizers, often burning, resulting in lack of seedlings. Prevention: The amount of fertilizer should not be too large, and no seed dressing such as superphosphate, ammonium bicarbonate, urea or lime nitrogen.
Toxic fertilizers Some fertilizers, such as lime nitrogen, must be subjected to a series of transformations to be absorbed by plants after they are applied to the soil, but some toxic substances will be produced during the transformation process to poison the crops, causing them to be killed or killed. Prevention: The application amount should be strictly controlled when applying fertilizer, and the fertilizer should be applied safely and rationally. (China Fertilizer Network)
