采用根瘤菌拌种,以氮素及根瘤菌为试验因素设置处理,随机区组设计,研究了氮和根瘤菌交互作用对大豆根瘤生长及大豆产量和品质的影响.结果表明,接入的根瘤菌能有效的增加大豆植株的结瘤数量,而施入大量的氮肥则产生抑制作用.根瘤菌的接入对大豆R3期生物量的积累产生一定的促进作用.在接入根瘤菌的条件下,施入氮肥单个根瘤体积增大;不施入氮肥,单个根瘤体积变小.产量构成因子综合作用的结果使得接种根瘤菌与施入氮肥相比,更能提高大豆的产量.

The interactive effects of rhizobium inoculation and nitrogen application on nodule development, yield and quality of soybean were studied with randomized complete block design. Results showed that the number of root nodules was increased significantly by rhizobium inoculation, but was inhibited under high lev?el of nitrogen. Significant improvement of plant biomass accumulation by inoculation rhizobium was found at R3 stage. Under inoculation conditions, the single root volume was increased with nitrogen treatment, but reduced without nitrogen. The interactive effects of yield components showed that the improvement of soybean yield was more significant with rhizobium inoculation than nitrogen treatment.
