摘要： 摘要：在大田条件下研究了三种氮素类型对豫豆29品种根瘤菌生长特性及产量和品质的影响。结果表明，在三种氮肥类型处理下，在各时期根瘤菌数量、体积；成熟期产量和籽粒品质性状与对照相比较均有不同幅度的升高。其中，铵态氮肥与其它处理相比较数量最高。说明施用铵态氮肥能够显著促进根瘤菌的生长，特别是生育后期，包括促进根瘤菌数量和体积的增加，能促进大豆生长，改善大豆籽粒品质性状。

Abstract: Abstract：The study aimed to analyze effects of three different types of nitrogen fertilizer on nodule growth characteristics and yields of Yu dou 29 soybean in the field conditions.The results showed that with three different types of nitrogen fertilizer treatment，It had different magnitude higher than the contrast,in the quanity and volume of rhizobium at all times,and in the quality traits at maturity. The NH2-N treatment(urea) compared with other treatments had the highest. With NH2-N treatment(urea) ,it can significantly promote the growth of rhizobia, Including the number and volume，at late birth particularly.It could also stimulate the growth of soybean,improved the quality traits of soybean.
