Which chemical fertilizers should not be applied to vegetables?
1. Ammonium Nitrate Other nitrate nitrogen fertilizers are generally not suitable for vegetables. Nitrate ammonia fertilizers will increase the nitrate content in vegetables after being applied to the vegetable field. Nitrate is easily reduced to nitrite and nitrite in the human body. It is a highly toxic substance that is extremely harmful to the human body.
2, dual chlorine fertilizer. Ammonium chloride and potassium chloride should not be applied to tomatoes and potatoes. After the chlorine-containing fertilizer is decomposed in the soil, ammonium or potassium ions will be absorbed by the soil or absorbed by the vegetables. When the concentration reaches a certain level, it will poison the roots of the vegetables and cause serious vegetable death.
3, leafy vegetables avoid nitrogen fertilizer applied to the foliage. When nitrogen fertilizer is sprayed on the leaves of vegetables, the ammonium ions are easily absorbed into leaves after contact with air, and the short growing period of leafy vegetables makes it easy to accumulate nitrate in the leaves. Applying micro-fertilizer to vegetables can promote the high quality and high yield of vegetables, but the demand for microelements in vegetables is very small. Excessive application of fertilizers not only results in waste, but counties tend to produce poisons and pollute the environment.
