对前期从植物根际分离的促生菌(PGPR)进一步测定，筛选出5株优良溶磷菌株和1株根瘤菌株，并利用其制成 PGPR 微生物肥，研究其替代20%~30%化肥对豌豆生长及产量的影响。结果表明：菌株 LM4-3、LH12-3、Lx191、Jm92、LHS11与 GDB27互不产生拮抗，可制成 PGPR 微生物肥，研制的 PGPR 微生物肥替代20%化肥可使豌豆株高增加6.3%，经济产量提高3.2%，减少可购买性投入220.00~358.00元/hm2。

The plant growth promoting rhizobacteria (PGPR)biofertilizer made from 5 phosphorous solving strains and 1 rhizobia was used to test the effect on pea growth through replacing 20% to 30% of chemical fer-tilizer under field condition.The results showed that 5 phosphorous solving strains (LM4-3,LH12-3,Lx1 91, Jm92,LHS1 1 and GDB27)did not show antagonistic effect each other and could be used for biofertilizer.The biofertilizer could replace 80% of chemical fertilizer and the height and seed yield of pea were increased by 6.3%and 3.2%,and the cost was reduced by 220 to 358 yuan/ha.
