New wheat variety dry-hot wind resistance identifying method and specialized temperature control shed

Abstract

The invention belongs to the technical field of a wheat new variety identifying method and a device thereof, and discloses a new wheat variety dry-hot wind resistance identifying method and a specialized temperature control shed. The method and the shed are mainly and technologically characterized in that the method comprises an output dry-hot wind resistance identifying method, a dry-hot wind resistance quality identifying method and comprehensive performance comparison; a dry-hot wind resistance index is utilized as a new dry-hot wind resistance identifying index; different outputs of different varieties are used as a reference; comprehensive consideration of relative output and absolute output of the variety is performed; the variety with high output in an abundant-water year and low output reduction in a dry year can be screened; through comparing with a contrasting variety, a dry-hot wind resistance grade is determined, thereby realizing more visual dry-hot wind resistance identifying result. On the condition of dry-hot wind invasion, relatively high quality is realized, and the dry-hot wind resistance quality grade of the tested variety is determined; so that more visual dry-hot wind resistance quality identifying result and high operability are realized. Compared with a multi-year multi-point testing method which is easily affected by natural factors, the method has higher comparability. The new wheat variety dry-hot wind resistance identifying method and the specialized temperature control shed are suitable for wheat quality dry-hot wind resistance breeding and dry-hot wind identifying in area testing.

Description

technical field [0001] The invention belongs to the technical field of a new wheat variety identification method and a temperature-controlled shed, and in particular relates to an identification method for a new wheat variety resistant to dry and hot wind and a special temperature-controlled shed. Background technique [0002] Dry and hot wind, also known as "dry wind" and "hot dry wind", is commonly called "fire south wind" or "fire wind". It is one of the agricultural meteorological disasters with high temperature, low humidity and certain wind force. It is a dry and hot wind that occurs during the warm season and causes damage to the wheat during the milk ripening period. During dry and hot wind, the temperature rises significantly, the humidity drops significantly, accompanied by a certain wind force, the transpiration intensifies, the root system does not absorb water enough, and the awns, ears, leaves and stems of wheat plants are all damaged. After dehydration from ...

Problems solved by technology

In terms of comprehensive evaluation of crop yield tolerance to dry and hot wind, although researchers have proposed various identification methods, none of them can comprehensively express the relative and absolute yield levels of wheat varieties under heat stress, and cannot explain high-yield or high-yield potential, which is difficult for breeding. provide the basis for selection of genotypes with high yield and tolerance to dry and hot wind

In terms of comprehensive evaluation of crop quality resistance to hot and dry wind, due to the large number of quality testing indicators and the large amount of flour required for testing, it is difficult to determine key indicators and provide breeding workers with a basis for selecting quality and hot and dry wind-resistant genotypes
