High-temperature drought stress resistance agent for plants and application of agent

Abstract

The invention relates to a high-temperature drought stress resistance agent and application of the agent and belongs to the field of crop planting. In order to overcome the technical defects that thestress resistance effect is poor by applying glycine betaine alone in the prior art and corresponding substitute products fall short in the market, the provided high-temperature drought stress resistance agent is prepared from glycine betaine, urea and Tween-20. When the agent is applied to annual seedlings or annual or biennial or triennial plants, drop of the chlorophyll content under an adversesituation can all be alleviated, and the photosynthetic capacity of leaves is improved. Accumulation of superoxide radicals (O2 -) in the leaves is reduced, the relative electrolytic leakage and membrane lipid peroxidation level of the leaves are lowered, plant resistance to drought and other stress is improved, and the agent is suitable for application and popularization in the agriculture.

Description

technical field [0001] The invention relates to a plant high temperature and drought stress resistance agent and application thereof, belonging to the field of crop planting. Background technique [0002] During the growth of crops, they are often subjected to complex and changeable adversity stresses, such as drought, heat damage, freezing damage, high light radiation, etc., which seriously affect crop growth. Low-temperature chilling damage, high-temperature heat damage, drought, salinity, waterlogging, pesticide damage and other phenomena occur frequently, which are important disasters that affect the sustainable and stable development of agricultural production, and thus seriously affect the economic benefits of farmers. Among them, high temperature and drought are the most common harsh environments that affect crop growth and crop yield. [0003] In response to the increasingly severe natural disasters of high temperature and drought, there is a lack of products on the...

AI Technical Summary

Problems solved by technology

[0007] In order to overcome the poor anti-stress effect of simply using glycine beet in the prior art, and the lack of corresponding substitute products on the market, the present invention provides a plant high-temperature drought stress-resistance agent, which is composed of betaine, urea and Tween When it is used for annual seedlings or 1-3 year-old plants, it can effectively alleviate the decline of chlorophyll content under adversity, improve the photosynthetic capacity of leaves; reduce the superoxide free radicals (O2 ·- ) accumulation, which reduces the relative electrical conductivity and membrane lipid peroxidation level of leaves, improves the stress ability of plants such as drought resistance, and is suitable for popularization and application in agriculture
