Abstract

The invention relates to the field of planting of crops, in particular to a method for reducing content of cadmium in crops. According to the method for reducing the content of the cadmium in the crops, an organic water-soluble fertilizer prepared from plant source organic matters, humic acid, citric acid, amino acid, vitamin and monosaccharide is applied to the crops mainly in an irrigation manner; through a specific amount of organic water-soluble fertilizer applied in an irrigation manner before planting, a specific amount of organic water-soluble fertilizer applied in an irrigation manner after planting and a specific amount of leaf fertilizer applied in a spraying manner in a growing period of the crops, nutrition can be supplied for the crops while cadmium absorption of roots of the crops is reduced, photosynthetic capacity of the crops is improved, stress resistance is improved, and an effect of improving the yield of the crops is also improved effectively. The method plays an important role in guaranteeing safety of agricultural products.

Description

technical field [0001] The invention relates to the field of crop planting, in particular to a method for reducing cadmium content in crops. Background technique [0002] Cadmium is not an essential element for the human body. Cadmium is highly toxic and can accumulate in the human body, mainly in the kidneys, causing functional changes in the urinary system. Since the discovery of cadmium in the early 20th century, the output of cadmium has increased year by year. A considerable amount of cadmium is discharged into the environment through waste gas, waste water, and waste residue, causing pollution. Cadmium entering the human body forms cadmium-sulfur protein in the body, reaches the whole body through the blood, and selectively accumulates in the kidney and liver. Cadmium binds to protein molecules containing hydroxyl, amino, and sulfhydryl groups, which can inhibit many enzyme systems. Thus affecting the normal function of the enzyme system in the liver and kidney orga...
