在人工诱发小麦结瘤中，Ｍｏ对小麦植株的生长发育、水份吸收和结瘤均有明显影响，但影响的浓度各不相同．以０～１８０ｍｇ／Ｌ的Ｎａ２ＭｏＯ４２Ｈ２Ｏ处理，当浓度为６０ｍｇ／Ｌ时，结瘤小麦植株对水分的吸收量最多；在８０ｍｇ／Ｌ时，苗最高，根最长，鲜重和干重最重；２０～８０ｍｇ／Ｌ时，结瘤数随浓度增加而增加，其中以８０ｍｇ／Ｌ为最多 In artificially induced nodulation of wheat, Mo had a significant effect on the growth and development of wheat plants, water absorption and nodulation, but the concentrations affected were different. When treated with 0 ~ 180mg / L Na2MoO42H2O, the maximum nitrogen uptake by the nodulated wheat plants was achieved at the concentration of 60mg / L. The highest seedling weight, the longest root weight and the heaviest fresh weight and dry weight at 80mg / When the concentration was 20 ~ 80mg / L, the number of nodules increased with the increase of concentration, of which 80mg / L was the most
