摘要: 为揭示滴灌高产冬小麦的物质生产规律,在滴灌(分别在越冬前、拔节期、孕穗期、开花期、花后12 d、花后20 d各滴水1次,每次滴水750 m3/hm2,共4 500 m3/hm2)条件下,田间比较了8个冬小麦品种的产量、群体发展动态和干物质积累与分配的差异。结果表明,品种间产量差异达极显著水平。高产品种具有最高总茎数多,成穗数多|群体最高叶面积指数值大,孕穗至成熟期间干物质积累量大|开花后干物质积累量及其对籽粒的贡献率均高的特点。新冬32产量最高(为8 376.3 kg/hm2),其穗数为736.70万穗/hm2,穗粒数为36.4,千粒质量为36.76g|群体最高总茎数为2 198.4万/hm2,成穗率为44.6%,最大LAI为6.12|成熟期干物质积累量为1 928.5 kg/hm2|开花后干物质积累量及其对籽粒的贡献率分别为7 125.95 kg/hm2,83.35%。

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 m3/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 ofgroups,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 tograin,which they were high. The yield of Xindong 32 is highest,and it is 8 376. 3 kg/ha,panicles is 736. 7×104/ha,grains per spike are 36. 4,1000-grain weight is 36. 76g;the highest total stem is 2 198. 4×104/ha,spike rate is 44. 6%,the biggest leaf area index is 6. 12;the quantity of dry matter accu-mulation is 1 928. 5 kg/ha;quantity of dry matter accumulation after anthesis and its ratio and contribution tograin,in the order of which are 7 125. 95 kg/ha and 83. 35%.
