接种根瘤菌对不同品种绿豆生长及产量的影响

摘要

To investigate the impacts of rhizobial inoculation on plant growth and yield traits of three different varieties of green bean, the field experiments were settled in Fangshan, Beijing. The study found that the impacts of Rhizobial inoculation could significantly promote the grourth of the green bean varieties No. 2 and Jiliu 9. Both nodule numbers were significantly increased; and the yield increased by 41% and 29% ; Rhizobial inoculation in varieties Zhongliu 5, however, the yield decreased, but total nodule number was significantly higher than that of the control and the main nodule number was also higher than the other two treatments. Thus we recommended that the application of Rhizobial inoculum should match the variety of legume plants.%在田间试验条件下,调查了品种2号、中绿5号和冀绿9号3个绿豆品种接种根瘤菌菌剂对植株及产量等性状的影响.研究发现,接种根瘤菌可显著促进品种2号和冀绿9号两个绿豆品种的生长,根瘤数量明显增多,产量分别增加41％和29％；中绿5号接种根瘤菌后,产量不增反降,但总根瘤数要明显高于对照,且主根瘤数也高于其他两个品种.从而建议根瘤菌的应用应与品种相匹配.
