Abstract

The invention discloses a method for reducing peanut seed cadmium content. The method comprises the following steps that a corn plant is soaked by a hydrogen dioxide solution with the volume ratio of 10% for 30 minutes; spores and mycelia are obtained by using a provided treating box (1); the root system of the corn plant is cut up into small sections with the length of 0.5-1mm, the small sections and the air dried spores and mycelia are added into a second matrix (8) with the ratio of 2:1:1 to be mixed uniformly, corn mycorrhiza fungi microbial inoculum (11) is obtained, and the quantitative range of the spores in every gram in the formed corn mycorrhiza fungi microbial inoculum (11) is from 12 to 14; according to the predetermined plant and row spacing way, a plurality of holes with the depths of 3 centimeters are dug out in cadmium-contaminated soil, a certain amount of water is poured into the holes, the corn mycorrhiza fungi microbial inoculum (11) with the weight ranging from 7 grams to 10 grams are added into the holes, then peanut seeds are put into the holes, and the holes are covered with a soil layer with the thickness of 1 centimeter.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to a method for reducing cadmium content in peanut seeds. Background technique [0002] Cadmium (Cd) is one of the "five poisons" of heavy metals. Excessive cadmium in the human body can lead to a series of diseases such as bone pain, kidney disease, and liver damage. Unlike other heavy metal elements, cadmium in soil is more easily absorbed by plant roots and enters the food chain, thus causing harm to human health. Studies have shown that cadmium in plants is more likely to bind to low-molecular-weight proteins, and oil crops with high protein content can usually accumulate more cadmium. Among them, peanuts are one of the crops with strong cadmium absorption capacity and easy accumulation of cadmium in seeds. one. Excessive cadmium content in peanuts has become an important factor restricting the export of peanuts and the development of related industries. [0003] At pr...
