摘要
通过小区试验对山宁17大豆新品种的根瘤菌拌种与施肥技术进行了研究。结果表明,接种根瘤菌与氮肥追施可获得较高产量,且在接种根瘤菌及磷钾肥相同的情况下,每666.7m2花期追施尿素3.75 kg的大豆产量最高,比对照(666.7m2基施尿素5 kg)增产5.33%,并优于等量缓释氮肥基施的效果。
The techniques of dressing seeds with rhizobium and fertilization for new soybean variety Shanning 17 were studied by plot experiment.The results showed that inoculating rhizobium and topdressing nitrogen fertilizer contributed to obtaining higher yield.Under the conditions of inoculating rhizobium and fertilizing with the same phosphorus and potassium fertilizers,topdressing 3.75 kg nitrogen fertilizer per 666.7m2at flowering stage had the highest soybean yield,which increased by 5.33% compared with that of control（basal applying 5 kg nitrogen fertilizer per 666.7m2）,and was higher than that of basal applying same amount of slow release nitrogen fertilizer.
