There are many kinds of chemical fertilizers, and there are more than 10 commonly used ones. Some fertilizers used in vegetables can improve the quality and yield, but some fertilizers can increase the yield when applied to vegetables, but it will cause toxin contamination of vegetables, causing food poisoning and even life-threatening. For example: Ammonium nitrate and other nitrate nitrogen fertilizers are generally not suitable for application to vegetables, especially leafy vegetables such as Cabbage, vegetables, spinach, etc., because the application of nitrate nitrogen fertilizers will increase the nitrate content of vegetables by several times. Salt is easily reduced to nitrite in the human body. Nitrite is a highly toxic substance that is harmful to the human body and is a carcinogen. Ammonium chloride, potassium chloride and other chemical fertilizers containing chlorine should not be applied to crops such as tomatoes, potatoes, sweet potatoes, and yellow crops. After the chlorinated fertilizer is decomposed in the soil, ammonia or potassium ions will be absorbed by the soil and absorbed by crops. When the concentration reaches a certain level, it will be toxic to the plant roots. It will reduce the starch and sugar content of the product, affect the yield and quality, and in severe cases it will cause the crop to die.
