摘要：以30份贵州大豆种质资源为材料,采用玉米与大豆间作的方式,对大豆的10个农艺性状及产量进行分析评价。结果表明:间作复合系统中各小区玉米产量差异不显著,30份大豆的产量损失率差异显著;在间作条件下,参试材料的株高、茎粗、主茎节数、底荚高度、有效分枝数、单株粒数、单株荚数、单株粒质量、百粒质量、倒伏率等都存在一定的变异,变异系数为8.2%~62.0%,说明参试大豆种质资源具有丰富的表型多样性;灰色关联分析结果表明,对间作大豆产量影响从大到小的性状依次为单株粒数、单株粒质量、有效荚数、有效分枝、百粒质量、茎粗、主茎节数、倒伏率、株高、底荚高度;利用系统聚类法将30份大豆材料分为耐荫型、中间型和敏感型3大类,各类群性状之间的差异较明显,其中单株有效荚多、单株粒多、有效分枝多、百粒质量较小的第Ⅰ类大豆材料耐荫性较强,适宜在贵州山地环境下间作种植。
In order to screen out optimal shade-tolerant soybean germplasm resources suitable for intercropping in mountainous environment,30 soybean germplasm resources in Guizhou intercropped with maize-soybean were used in this study.The 10 agronomic characters and yield of the test materials under intercropping were collected and evaluated.The results showed that in the intercropping system,the yield of maize in each plot was not significantly different,while the yield loss of soybean was significantly lower than that of the net intercropping system.The inspection traits of the samples had some variation under intercropping conditions,and the variation coefficient is between 8.2%and 62.0%,indicating that the soybean germplasm resources have rich phenotype diversity.The grey correlation analysis showed that the traits affecting intercropping soybean yield were single grain number,effective pod number,stem length,weight of 100 grains,effective branch number,main stem node number,height of bottom pod,plant height and reflux rate.The 30 soybean materialscould be grouped into three categories:the shade resistant group,the intermediate group and the sensitive groups.These groups showed obvious difference on the studied traits.Among them,the group owning many single plants,many branches,and moderate weight,is the optimal soybean material suitable for intercropping in mountain environment.
