Problems solved by technology

[0004] So far, there has been no report on exogenous BR to alleviate corn deep-sowing stress, let alone the effect and optimal concentration of exogenous BR on corn deep-sowing stress. Corn is the largest food crop in China. In agricultural production, It is of great significance to develop safe and reliable drought prevention and resistance measures to improve corn drought resistance and ensure food security

Abstract

The invention provides a method for relieving corn deep sowing stress by applying exogenous brassinosteroid, and relates to the field of corn safety production guarantee, and the method comprises material collection, BR treatment liquid preparation, seed treatment, deep sowing stress test, determination item and determination method, optimal concentration application and result analysis. According to the method, the relieving effect of the BR on the deep sowing stress of the corn seedlings under different concentrations is evaluated, the effect of relieving the deep sowing stress of the corn seedlings by the exogenous BR is scientifically, objectively and comprehensively evaluated by adopting a membership function method, a theoretical foundation is laid for improving the deep sowing resistance of the corn, a technical reference is provided for rapid application of the exogenous BR and screening of the optimal concentration, and the method has a wide application prospect. The application prospect is wide.

Description

technical field [0001] The invention relates to the field of corn safety production assurance, in particular to a method for alleviating corn deep-sowing stress by applying exogenous brassinosteroids. Background technique [0002] Drought is one of the main abiotic factors affecting agricultural production and development. About 36% of the world's regions are arid and semi-arid regions, and their areas are increasing year by year. At present, the development status of our country is the rapid economic and population growth. Growth, agriculture and domestic water demand are becoming more and more tense, which makes the shortage of water resources more and more serious, which will not be conducive to the sustainable development of agriculture. The deep sowing planting method can make the seeds make full use of the limited water in the soil layer, which is considered to be a An effective way to deal with drought has attracted extensive attention from researchers, because deep-s...
