After insufflating extended endophytes phomopsis B3 ferment diluent on seedling bed of rice,the effect of microbial inoculum on rice growth was studied.The investigation result of seedlings before transplanting seedling showed that leaf age,the number of green leaves,the number of tiller of individual plant and the weight of per 100 fresh plants in microbial inoculum treatment group increased 0.11,0.12,0.03 and 2.6 g respectively compared with those of control group.20 days after transplanting,increased tiller number in microbial inoculum treatment group was 55 500 hm2 more than that in control group.30 days after transplanting,tiller number in microbial inoculum treatment group was 42 000 hm2 more than that in control group.In harvest season,the yield,weight of 1 000 grain and seed-setting rate increased 300 kg/hm2,0.7 g and 0.23% respectively compared with these in control group.The result of preliminary study demonstrated that microbial inoculum confected by endophytes phomopsis B3 could increase the number of strong seedling and yield.
