滴灌条件下不同冬小麦品种物质生产特性的差异
Studies on the Different Characteristics of the Dry Matter Production of the High Yield Winter-wheat Varieties under Drip Irrigation Conditions
摘要
Abstract
Under the field drip irrigation condition,eight different varieties were compared with the difference that they were different in the yield,dynamic of development of community and dry matter accumulation .It was five times water that was dripped and drip water order jointing stage ,booting stage,flowering,12 days after flowering (12DAF) and 20DAF,the water quantity was 750 m 3/ha,The result showed that the diversity of yield reached ex-tremely significant level.They were more that the highest total stem number and ear number of the high yielding va -rieties;not only the values was big for the highest leaf area index of groups ,but dry matter accumulation quantity was more from booting to maturity;and the characteristics as follows:the quantity of dry matter accumulation after anthesis and its ratio and contribution to grain ,which they were high.The yield of Xindong 32 is highest,and it is 8 376.3 kg/ha,panicles is 736.7 ×10 4/ha,grains per spike are 36.4,1000-grain weight is 36.76 g;the highest total 4/ha,spike rate is 44.6%,the biggest leaf area index is 6.12;the quantity of dry matter accu-stem is 2 198.4 ×10 mulation is 1 928.5 kg/ha;quantity of dry matter accumulation after anthesis and its ratio and contribution to grain , in the order of which are 7 125.95 kg/ha and 83.35%.关键词
