两种灌水量对冬小麦农艺性状及产量的影响
Effects of Two Irrigation on the Agronomic Traits and the Yield of Winter Wheat
摘要
Abstract
Objective]In order to explore winter wheat drought-resistant germplasms in different irriga-tion treatments,the project aims to screen wheat germplasm resources in the filed to widen the range of Xin-jiang winter drought-resistance germplasm resources and breeding.[Method]There were 20 kinds of winter wheat,which four from Xinjiang and 16 from Huanghuai area were chosen to investigate 9 characters under 5 irrigation times and 3 irrigation treatments.The nine characters were:number of spikes per plant,plant height,ear length,the sterile of basal spikelet,the sterile of top spikelet,spikelet number,kernels per spike,thousand kernel weight and yield.[Result]9 agronomic characters of 20 copies of the material was sig-nificantly different from each other,most of the average of 5 irrigation treatment times were higher than 3 times under this two kinds of irrigation treatment;the variation coefficient of each character was exactly different;Various characters drought-resistant coefficient ranged from 0.75 to 1 .13;Yield difference reached signifi-cant level,which under the condition of two irrigation treatment quantity,production always within the top seven were Shannon 15,Yannong 23,Xindong 20,Xindong 22 and Xindong 18;Production in the post six were Shannong 12,Taishan 22,Shi 4185,Shixin 616 and Shimai 18.[Conclusion]Increasing irrigation times can increase winter wheat yields.Especially in the seedling tillering and grain filling stage of grain matu-ration,keeping enough water supply can to improve the winter wheat yield.Compared with Huanghuai winter wheat varieties,winter wheat varieties bred in Xinjiang showed stronger drought resistance.关键词
