Method for strengthening abiotic environmental stress resistance of crops

Abstract

The invention provides a method for strengthening the abiotic environmental stress resistance of crops. The method comprises the steps of putting seedlings in a simulation pool of abiotic environmental stress; uniformly sprinkling a plant growth regulator solution containing 1-aminocyclopropane-1-carboxyl and methyl jasmonate at the same time onto the leaves of the seedlings, wherein the sprinkling amount is as the criterion when all the leaves are completely wetted by the growth regulation solution. The method is a growth regulation mode capable of obviously increasing the accumulation of nitric nitrogen at the roots of the crops, so that the abiotic environmental stress resistance of the crops is obviously improved, and the abiotic environmental stress resistance of the crops for heavy metal contamination and salt stress in a growing environment is strengthened.

Description

technical field [0001] The invention relates to a crop cultivation and growth regulation method, in particular to a method for increasing the distribution ratio of nitrate nitrogen in crop roots through the application of a plant growth regulator, thereby enhancing the stress resistance of crops. Background technique [0002] About 20% of the earth's surface soil is affected by environmental abiotic stresses. These soils are found not only in deserts and semi-deserts, but also in densely populated irrigated areas such as fertile plains, river valleys, and coasts. Environmental abiotic stress can be mainly divided into two types: wetland stress and drought stress. Wetland stress refers to marsh areas near the sea, which are affected by the high salt content of seawater and produce salt stress. Dryland stress is mainly distributed inland on the edge of deserts. Other stresses affect mainly inland lake and river areas. Environmental abiotic stress refers to the salt or heav...

Problems solved by technology

[0007] The technical problem to be solved by the present invention is to practically apply the theoretical knowledge mentioned in the above background technology through the addition of crop exogenous growth regulating substances (1-aminocyclopropane-1-carboxylic acid and methyl jasmonate), Provide a growth regulation method that can significantly increase the accumulation of nitrate nitrogen in the roots of crops, thereby significantly improving the resistance of crops to environmental abiotic stress, and enhancing the resistance of crops to environmental abiotic stress such as heavy metal pollution and salt stress in the growth environment
