A method for reducing chromium 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 heavy metal chromium content in tobacco leaves. This method uses the technical principle of molybdenum to antagonize chromium, and by adding trace element molybdenum in the process of tobacco planting, thereby antagonizing the absorption and utilization of chromium 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 chromium content in tobacco leaves provided by the application has the characteristics of low cost, simplicity, practicality and reliability, can fundamentally reduce the chromium content in tobacco leaves, and can lay a foundation for the stability and improvement of tobacco leaf quality.

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 chromium in tobacco leaves. Background technique [0002] In recent years, with the emphasis on heavy metal pollution research, a lot of research has been done on the behavior and control of heavy metals in tobacco at home and abroad. Existing studies believe that during tobacco smoking, heavy metals adsorbed in tobacco can enter the human body through mainstream smoke, making smoking one of the important sources for smokers to ingest certain heavy metals. [0003] Some studies believe that chromium is one of the main chemical elements that pollute tobacco in tobacco planting. Since tobacco is a plant that is easy to absorb and accumulate heavy metals, when the heavy metals in the tobacco leaves are excessive, the heavy metals will be released into aerosols during the smoking process. Or the form o...

Problems solved by technology

[0005] As far as tobacco planting is concerned, due to the strong tolerance of tobacco, some tobacco is planted in chromium-contaminated soil, which leads to high chromium content in these tobacco plants, reduces the quality of tobacco, and also contributes to the health of tobacco smokers. poses a potential hazard
