There are many types of chemical fertilizers, and more than 10 are commonly used. Some chemical fertilizers can improve the quality and yield after being used in vegetables, but some chemical fertilizers can increase the yield, but can cause toxin pollution in vegetables, cause food poisoning, and even endanger life.
For example, ammonium nitrate and other nitrate nitrogen fertilizers are generally not suitable for use in vegetables, especially leafy vegetables such as cabbage, greens, spinach, etc., because nitrate nitrogen fertilizers will double the nitrate content of vegetables when applied to vegetable fields.
Nitrate is easily reduced to nitrite in the human body. Nitrite is a highly dangerous drug, which is extremely harmful to the human body and is a carcinogen.
Fertilizers containing chlorine, such as ammonium chloride and potassium chloride, should not be applied to crops such as tomatoes, potatoes, and sweet potatoes, because ammonia or potassium ions will be absorbed by the soil and absorbed by the crops after the chlorinated fertilizer is decomposed in the soil.
When its concentration reaches a certain level, it will cause damage to plant roots, which can reduce the starch and sugar content of the product, affect yield and quality, and seriously cause crop death.

Vitamins are a type of trace organic substances that humans and animals must obtain from food in order to maintain normal physiological functions. In terms of physiological functions, vitamins are neither a raw material for tissues nor a substance for supplying energy, but they are an indispensable substance for the body. It has many types and different chemical structures. Most of them are the components of the coenzyme (or prosthetic group) of certain enzymes. They are the indispensable compounds for maintaining the normal growth (growth, health, reproduction and production function) of the body. It plays a catalytic role in the body to promote the synthesis and degradation of major nutrients (proteins, fats, carbohydrates, etc.), thereby controlling metabolism. Vitamins are essentially low-molecular organic compounds. They cannot be synthesized in the body, or the amount synthesized is difficult to meet the needs of the body, so they must be supplied from the outside. The daily requirement of vitamins is very small (usually measured in milligrams or micrograms). They are neither a raw material for body tissues nor a substance for energy supply in the body. However, they do not regulate material metabolism, promote growth and development, and maintain physiological functions.
