摘要
为研究滴灌条件下不同冬麦行间产量性状的差异,采用大田调查和室内考种的方法,于冬麦成熟期取样并进行室内考种。结果表明:在一个冬麦播幅铺设6根滴灌带的配置下,离滴灌带距离不同的冬麦行,产量性状存在差异。离滴灌带远的冬麦行收获穗数较多,折合产量高。离滴灌带近的小麦虽然群体数量较少,但个体发育高于离滴灌带远的冬麦行,上述差距均不显著。主茎穗及分蘖穗产量性状无明显变化规律,差异亦不显著。无论是主茎穗还是分蘖穗,穗粒数均呈双峰曲线分布,总小穗数均呈单峰曲线分布,不同小麦行间穗粒数及总小穗数分布无明显规律可循。
To evaluate the difference of winter wheat yield traits between the different rows under drip irrigation, plants were sampled to measure yield traits at the maturity stage of winter wheat. The re- sults showed that： yield traits were significantly different between different rows with different dis- tance to the drip tape. Rows far from the drip tape harvested more panicles and higher yield per-mu. Individual plants in the rows near to the drip tape grew better with less density, so the differences of yield per mu in different rows were not significant. The main spike and tiller spike showed no regular tendency and without significant differences. Grain number of main spike and tiller spike distributed with a bimodal distribution curve, and the total number of spikelet showed unimodal curve distribu- tion. Grain number and total number of spikelet of different rows of wheat distributed without clear tendency.
