摘要:

为了筛选出适宜与高秆作物间套作的菜用大豆品种,以10个菜用大豆品种为对象,分别在四叶期和初花期进行遮阴50%的处理,检测其对10个菜用大豆品种农艺性状、产量,以及根系硝态氮( NO 3 --N)含量和硝酸还原酶(NR)活性的影响,运用综合隶属函数法对10个菜用大豆品种的耐阴性进行比较。结果表明,不同时期遮阴50%,部分菜用大豆品种的株高、结荚高度、分枝高度和根系 NO 3 --N含量显著(P<0.05)增高,但产量和NR活性显著降低。基于综合隶属函数法评价结果,淮鲜17-08、开鲜3号、淮鲜豆5号、翠绿玉等4个品种的耐阴性较强,适宜与高秆作物间套作。

Abstract:

In order to screen out suitable vegetable soybean varieties for intercropping with high stem crops, 10 vegetable soybean varieties were selected as test materials. The effects of 50% shading at either four leaf stage or early flowering stage on agronomic characters, yield and root nitrate nitrogen ( NO 3 --N) content and nitrate reductase (NR) activity were explored. Besides, the shade tolerance of 10 vegetable soybean varieties were determined via comprehensive membership function method. The results showed that, the plant height, pod setting height, branch height and root NO 3 --N content of some vegetable soybean varieties were significantly (P<0.05) increased, yet the yield and NR activity were significantly decreased under 50% shading. Based on the constructed comprehensive membership function value, it was found that Huaixian17-08, Kaixian No. 3, Huaixiandou No. 5 and Cuilyuyu had stronger shade tolerance, and were suitable for intercropping with high stem crops.
