| 摘 要： | 对吉林黑土和辽宁棕壤上的１８个大豆品种分别作了自然固氮能力调查，结果说明在同样条件下不同种质大豆的固氮能力有很大差异。两年结果表明，吉林２１，吉林２３，长８２１０－４，吉林２７等有较高的固氮能力。吉２３无论植株干重还是固氮量均为最高。辽宁以辽８６－５４５３，辽８５－８５３８，８３－５０２０表现较好，其中辽８６－５３５３最好。同时还讨论了同一大豆品种不同菌株共生时对共生体系固氮能力的影响。

| Abstract: | Natural NZ2-fixing ability of 18 soybean cultivars were investigated on black soil of Jilin and brown soil of Liaoning.Results indicated that under the same conition the N2-fixing ability among different cultivars varied significantly. Results of two years showed that Jilin 23,Jilin 21,Chang 8210-4,and Jilin 27 etc. had high N2-fixing ability,while Jilin 23 had the highest dry weight and the amount of nitrogen fixed. Liao 86 - 5453, Liao 85 - 8538, and 83- 5020 were relatively good cultivars in this respect in Liaoning province. The differences in N2-fixing ability of symbiotic associations between the same cultivar and different strains were discussed. |
