光合细菌对大豆的根瘤及产量的影响

Effects of Photosynthetic Bacteriaon Nodule and Yield of Soybean

以高油大豆品种吉育202和普通大豆品种延11为试验材料,探讨在各生育期光合细菌处理对大豆的农艺性状、根瘤、脂肪以及产量的影响。结果表明:1)处理3的根长、根瘤数、根干重在始花期差异显著,处理6的农艺性状除始花期外整个生育期差异最明显;2)光合细菌含量的增加,大豆的产量和脂肪含量明显提高。

Soybean varieties yan 11 and jiyu 202 as experimental material, effects of photosynthetic bacterial on the agronomic trait,nodules, fat content and yield of soybean were studied. The results showed that: 1) On root length, nodule number and root weight of treatment 3,there were significant differences in the beginning of flowering. On agronomic trait of treatment 6,there were significant differences except for beginning of flowering. 2) As content of photosynthetic bacteria levels increased,the yield and fat content of soybean were increased as well.
