Abstract

The invention provides a method for improving water logging stress resistance of wheat. The method comprises the following steps: (1) soaking wheat seeds with 200mg / L of salicylic acid for 24 hours before planting; and (2) after the soaked wheat seeds germinate, spraying seedlings with 200mg / L of salicylic acid. According to the wheat seeds and seedlings thereof processed by the method disclosed by the invention, the damage to the growth condition is smaller than that after suffering from floods.

Description

technical field [0001] The invention relates to the field of agricultural production, in particular to a method for improving wheat waterlogging stress resistance. Background technique [0002] As the main source of food for human beings, wheat plays a pivotal role. However, when farmers plant wheat and the wheat is waterlogged due to weather irresistible factors, the output of wheat will drop sharply that year or even lose grains. harvest, seriously affecting the income of farmers. Contents of the invention [0003] The purpose of the present invention is to solve the above-mentioned defects in the prior art and provide a method capable of improving the resistance of wheat to waterlogging stress. [0004] A method for improving wheat waterlogging stress resistance, comprising the following steps: [0005] (1), wheat seeds were soaked with 200mg / L salicylic acid for 24 hours before planting; [0006] (2), after the soaked wheat seeds are planted and sprouted, the seedli...
