| 摘 要： | 采用盆钵实验，在小麦与紫云英混作系统中，通过对紫云英接种根瘤菌，研究了小麦与紫云英生长过程中植株生长、植株生物量、植株与土壤氮素变化情况及根瘤菌的酶活性．结果表明，在有根瘤菌接种的混作体系中，植株的生长得到促进，植株及土壤全氮均有增加，酶活性比单作也有所提高．

| Abstract: | Inoculation experiments were carried out in wheat astragalus mixed cropping system to study the changes of plant biomass, nitrogen content in plants and soil, and enzyme activity of Rhizobium . The results showed that in the mixed cropping system inoculated with Rhizobium , the growth of plants was stimulated, total nitrogen of plants and soil was increased significantly, and the increment of enzyme activity of Rhizobium was also found. |

| Keywords: | Rhizobium Mixed cropping Wheat Astragalus Biomass Nitrogen. |
