A kind of method for reducing arsenic content in tobacco leaves

Abstract

The invention belongs to the technical field of tobacco planting, and in particular relates to a method for effectively reducing the content of heavy metal arsenic in tobacco leaves. This method uses the technical principle of molybdenum to antagonize arsenic, and by adding trace element molybdenum in the process of tobacco planting, it antagonizes the absorption and utilization of arsenic by tobacco. , evenly spray soluble molybdenum salt (or directly dissolve in irrigation water) into the cultivation soil; in the later stage, follow the conventional field management measures for cultivation and management; the specific dosage of soluble molybdenum salt is: 700~1100mg / L , the application amount in the soil is: 400~600L / mu, that is, 0.28~0.66kg / mu. The method for reducing the arsenic content in tobacco leaves provided by the application has the characteristics of low cost, simplicity, practicality and reliability, can fundamentally reduce the arsenic content in tobacco leaves, and can lay a foundation for stabilizing and improving the quality of tobacco leaves.

Description

technical field [0001] The invention belongs to the technical field of tobacco planting, and in particular relates to a method for effectively reducing the content of heavy metal arsenic in tobacco leaves. Background technique [0002] In environmental governance, heavy metals refer to a class of chemical elements that are highly harmful to the human body. In addition to the conventional metal elements such as lead, nickel, chromium, and cadmium, it also includes the metalloid element arsenic. The main reason is that the arsenic element enters The pathological and toxic properties caused in organisms are very similar to those of heavy metals, so they are usually studied as one of the heavy metal elements. [0003] In recent years, with the emphasis on research on heavy metal pollution, a lot of research has been done abroad on the behavior and control of heavy metals in tobacco. Existing studies believe that during tobacco smoking, heavy metals adsorbed in tobacco can enter...

Problems solved by technology

[0006] As far as tobacco planting is concerned, due to the strong tolerance of tobacco, some tobacco is planted in arsenic-contaminated soil, which leads to high arsenic content in these tobacco plants, reduces the quality of tobacco, and also contributes to the health of tobacco smokers. poses a potential hazard
