Glutamine inhibits the absorption of Pb in Chinese cabbage and improves the ability to resist Pb pollution

Abstract

The invention discloses an application and method for using glutamine treatment to inhibit the absorption of heavy metal Pb by plants, reduce the heavy metal pollution of vegetables, and reduce the damage and growth inhibition of vegetables by Pb. The present invention utilizes glutamine treatment to inhibit plants from absorbing Pb in the soil, and by applying 10 mmol / L glutamine to vegetables such as pakchoi grown in different Pb-contaminated soils, it can effectively inhibit the absorption of Pb from the soil by pakchoi and reduce Pb Accumulate in the roots, stems and leaves of Chinese cabbage to reduce Pb pollution in Chinese cabbage.

Description

technical field

[0001] The invention belongs to the field of agricultural biotechnology, and specifically relates to an application and a method for using glutamine treatment to inhibit the absorption of heavy metal Pb by pakchoi and improving the anti-Pb pollution ability of pakchoi. Background technique

[0002] The people regard food as the first priority, and food safety is the first priority. Food safety is a major issue related to the national economy and people's livelihood. Agricultural products can not only be eaten directly, but also the basic raw materials for food processing. Their safety has a decisive impact on the safety of ordinary people's vegetable baskets and rice bags. In recent years, the safety of agricultural products caused by soil and other environmental heavy metal pollution has become increasingly serious. Environmental pollution safety incidents of agricultural products with excessive heavy metal content including lead (Pb) have occurred frequentl...
