Chemical fertilizers can help farmers increase production and income, but poor use may cause big troubles, not only adversely affecting crops, but even toxic and harmful substances may appear. Some fertilizers should be used with caution on vegetables. Chlorine-based fertilizer The compound fertilizer containing ammonium chloride and potassium chloride is called dichloro compound fertilizer, and it is not suitable for tomato and potato. After the dichloride fertilizer is decomposed in the soil, the ammonium or potassium ions will be adsorbed by the soil or absorbed by the vegetables. When the concentration reaches a certain level, it will be poisonous to the roots of the vegetables, and will cause the death of the vegetables. However, low-chlorine (referring to only potassium chloride) compound fertilizer can effectively supplement the chlorine element, can promote the growth of tomatoes and potatoes, and rational use can increase production. Nitro fertilizer Ammonium nitrate and other nitrate nitrogen fertilizers are generally not suitable to be applied to vegetables. Nitrate nitrogen fertilizer will double the nitrate content in vegetables when it is applied to the vegetable field. Nitrate is easily reduced to nitrite in the human body. Nitrite is a highly toxic substance that is extremely harmful to the human body. Nitrogen fertilizer Avoid spraying nitrogen fertilizer on leafy vegetables. When vegetable leaves are sprayed with nitrogen fertilizer, the ammonium ions are easily converted into acid root ions and absorbed by the leaves after contact with the air. In addition, the short growth period of leafy vegetables makes it easy for nitrate to accumulate in the leaves. Therefore, avoid spraying nitrogen fertilizer on the leaf surface of leafy vegetables. Micro-fertilizer The application of micro-fertilizers to vegetables can promote high-quality and high-yield vegetables, but the demand for trace elements in vegetables is very small. Excessive application of micro-fertilizers will not only cause waste, but also be toxic to crops and pollute the environment.
