闻喜旱区不同品种小麦水分利用和产量形成的差异
The study of different wheat varieties on water use and yield formation of dryland wheat in Wenxi
摘要
Abstract
In order to filter out high-yield and more efficient varieties of wheat which were suitable for the dryland wheat area.1 6 wheat varieties were selected in Wenxi County,Shanxi Province in field.According to the analysis of yield, the different varieties were classified into two groups of high yield and low yield.Eight wheat varieties of two types were selected to study the difference of water and yield.The results showed that the value of soil water storage in dif-ferent growth stages,dry weight of plant in different growth stages,plant height,spike length,bearing spikelet num-ber,spike number,grain number,yield and WUE of high yield were higher than low yield.Soil water storage from wintering stage to booting stage,dry weight of plant in different growth stages,spike number,grain number,yield and WUE were higher in LY81 59 and SM1 9 among high yield varieties,which were higher in YH618 and CM25 1 a-mong low yield varieties.Plant height and bearing spikelet number were higher in LY81 59 among high yield varieties, which were higher in YH618 and CM25 1 among low yield varieties.Spike length and sterility spikelet number were higher in YH20410 and YH805 among high yield varieties.Spike length was higher in YH618 and CM25 1 among low yield varieties.Sterility spikelet number was higher in CM6697 and LH1 1 among low yield varieties.5 ~ 35 d 1000-grain weight after anthesis and 1000-grain weight at maturity were the highest in YH20410 among high yield varieties, which were the highest in YH1 1 among low yield varieties.To sum up,the water and yield were higher in LY81 59 and SM1 9 among eight wheat varieties,which are more suitable for the dryland wheat area as high-yield and more efficient varieties.关键词
