Abstract: In order to investigate the effects of inoculation soybean rhizobia at different nitrogen levels on the growth and physiology of hybrid soybeans (Glycine soja Sieb.et Zucc), in this study ‘Mengnong S006 hybrid forage soybean’ (Glycine soja Sieb.et Zucc cv. Hybrid F-S006), referred to as S006, was planted with vermiculite, and four nitrogen levels CK(0 g·kg-1), N1(0.714 g·kg-1), N2(1.428 g·kg-1) and N3 (2.142 g·kg-1) were set up. Three strains of rhizobia isolated from the root nodules of S006 in the experimental planting plot were respectively inoculated and named (Z1, Z2, Z3). The effects of rhizobia inoculation at different nitrogen levels on plant height, nodules, leaf length, leaf width, biomass, photosynthetic indexes, soluble sugar content, catalase content and other indexes of S006 were studied. Thirty days after inoculation with rhizobia, the growth indexes and physiological indexes of S006 were measured. The results showed that the application of nitrogen at N2 level could significantly increase the photosynthesis and biomass of S006, and the physiological effect was more significant under the treatment of Rhizobia Z1.

摘要: 为研究在不同氮素水平下接种大豆根瘤菌对杂交饲用大豆(Glycine soja Sieb.et Zucc)生长和生理的影响,以‘蒙农S006饲用大豆’(Glycine soja Sieb.et Zucc cv. Hybrid F-S006),简称S006,为试验材料,采用蛭石种植,设置4个氮素水平CK(0 g·kg-1),N1(0.714 g·kg-1),N2(1.428 g·kg-1),N3(2.142 g·kg-1),分别接种3株分离自试验地种植小区中S006根部根瘤的根瘤菌命名为(Z1,Z2,Z3),研究在不同氮素水平下接种根瘤菌对S006株高、根瘤、叶长、叶宽、生物量、光合指标、可溶性糖含量、过氧化氢酶含量等指标的影响。接种根瘤菌后30 d后,对S006生长指标和生理指标进行测定。结果显示,在施用氮素为N2水平下,能显著增加S006的光合作用和生物量,且在根瘤菌Z1的处理下,对生理的影响较为显著。
