摘  要:
After treatment with extended endophytes Phomopsis B3 fermented diluent on the seedling bed of rice, the effect of microbial inoculum on rice growth was studied. Before transplanting, seedlings showed that leaf age, the number of green leaves, the number of tillers of individual plants and the weight of per 100 fresh plants in microbial inoculum treatment group increased by 0.11,0.12,0.03 and 2.6 g, respectively, compared with those of the control group. Twenty days after transplanting, the increase in the tiller number in microbial inoculum treatment group was 55 500 hm2 more than that in the control group. Thirty days after transplanting, tiller number in microbial inoculum treatment group was 42 000 hm2 more than that in the control group. In the harvest season, the yield, weight of 1000 grain and seed-setting rate increased by 300 kg/hm2, 0.7 g and 0.23%, respectively, compared with those of the control group. The results of the preliminary study demonstrated that microbial inoculum from endophytes Phomopsis B3 could increase the number of strong rice seedlings and yield.
