摘　　要：研究了不同紫花苜蓿品种不同处理方式接种根瘤菌的效应。结果表明,接种匹配的根瘤菌能显著提高紫花苜蓿的结瘤量和结瘤率;对植株粗蛋白含量的提高作用不大,但能有效提高紫花苜蓿的生物学产量和粗蛋白的产量;与植株根部氮含量虽有一定相关性,但相关程度不高;并且根瘤菌直接拌种后下播的处理比根瘤菌拌土后再播种的效果要好。The effect of inoculating nodul bacterials on nodules and biomass yields of different alfalfa cultivars was investigated. The results indicated that nodule numbers and nodule percentages were significantly improved by inoculating matched rhizobial strain. Inoculating rhizobial strain were significantly increased biomass yield and crude protein of alfalfa, but crude protein contents in whole plants was not increased obviously. The nitrogen contents in the plant roots were not correlated with inoculation of rhizobial strain. The effects of increasing nodule percentage and biomass yields of inoculating rhizobia on seeds were greater than that of inoculating rhizobia on soil.
