新疆小麦品质生态区划研究
Study of Ecological Division for Wheat Quality in Xinjiang
摘要
Abstract
[Objective] The quality traits and ecological factors of wheat growing areas in Xinjiang were studied,and the best planting area of high quality wheat was determined.Also,the quality zoning of wheat in Xinjiang was evaluated accurately.[Method] 15 winter and spring wheat varieties of three gluten type was selected and identified in 34 spring and winter wheat typical ecological regions of Xinjiang.At the same time,we carried out canonical correlation analysis of quality characters based on temperature,precipitation and sunshine hours in the stages from wheat heading to maturity and,finally the effects of geographical factors and climatic factors on wheat quality were determined and the quality types of wheat in different ecological zones were reviewed.[Result] The grain protein content,sedimentation value,development time,stability time,evaluation value,extension area,resistance to extension,extensibility and maximum resistance to extension nine quality indictors had a significant level between three winter wheat quality types.But in spring wheat the strong gluten cultivar and medium-weak gluten culdvar had no significant difference,the indicators of water absorption between strong gluten cultivars and medium-weak gluten cultivars had no significant difference,strong gluten cultivars was significantly bigger than medium-weak gluten cultivars on other quality indicators;the farinograph and extensograph parameter medium-strong gluten cuhivars had the greatest variation,the second one was strong gluten varieties,the smallest variation was medium-weak gluten varieties,which showed that the quality traits of strong gluten varieties were affected by environmental impact than medium-weak gluten wheat varieties.The analysis results of canonical correlation variable showed that there was a significant correlation between quality traits and ecological factors,and the effects of different ecological factors on quality traits were different.At the same time,it also indicated that between quality traits and ecological factors had a significant correlation in the stage from wheat heading to maturity,but between winter and spring wheat the ecological factors had a different influence.The mean temperature had the greatest effect on quality trait of winter wheat;the second were maximum temperature and latitude.However,the mean temperature had the greatest effect on quality trait of spring wheat,the second were lowest temperature and altitude.[Conclusion] The research results confirmed the planting areas of strong gluten,medium-strong gluten and medium-weak gluten varieties and accurately described planting map of ecological division for wheat quality in Xinjiang.关键词
