| 摘 要： | 筛选出5株植物根际菌株与1株根瘤菌制成复合菌肥,将研制的菌肥和1种引进的菌肥替代20%～30%化肥与全量化肥作对比,研究4种肥料处理对单作玉米生长的影响。结果表明:菌株LM4-3、LH12-3、Lx191、Jm92、LHS11和GDB27之间互不拮抗,可制成复合菌肥;自制复合菌肥替代20%化肥用量可使成熟期玉米地上生物量鲜重提高10%,替代20%～30%的化肥可提高4%～8%的籽实产量,优于引进的菌肥;以复合菌肥替代20%～30%的化肥施用于玉米后,玉米生长良好。

| Abstract: | The effect of reducing 20%~30% chemical fertilizer insteaed of plant growth promoting rhizobacteria(PGPR) compound biofertilizer on Maize was measured under field condition.The results showed that five PGPR strains,LM4-3,LH12-3,Lx191,Jm92 and LHS11,have no antagonism to each other and could be mix-cultured and produce compound bioferitilizer.The compound bioferitilizer with 80% dose of Chemical Fertilizer could increase above ground biomass of maize by 10% and enhance yield of seed by 4%~8% comparing to 100% dose of chemical fertilizer under field condition.Thus,the application of compound bioferitilizert could replace 20% to 30% fertilizer. |
