摘要
目的:探讨PGPR植物促生肥在大豆上的应用效果。方法:采用田间小区随机试验及大区简单对比处理、拌种及作种肥施用方式进行,生育期调查,对产量及产量构成因子进行比较分析。结果:大区对比试验,亩施100ml液体菌剂或1.0kg粉剂拌种,与常规施肥的对照相比,大豆早熟2~3d,根瘤数增加3.0~26.8个/株,百粒重增加0.2~0.8g,产量提高3.2%~12.7%。除1个试验点因低温干旱增产不明显外,其余试验点增产率都超过6%。其中,液体拌种平均增产9%,固体粉末作种肥平均增产9.3%,与小区试验结果基本相吻合。结论:PGPR植物促生肥在大豆上应用效果稳定,增产显著,具有实际推广应用价值。
Objective： The effect of soybeans was explored when PGPR was applied in soybeans. Method： The field plot randomized experiment and the regional simple contrast experiment were adopted through the different using way of seed dressing and seed manure , then the period of duration of soybean was investigated and the yield was compared and analysed. Result：The field experiment had be shown that the period of soybean maturity was advanced 2 - 3d, the soybean nodule number was increased by 3.0 - 26.8 a per strains, 100 kernel weight was increased by O. 2 -0.8 g ,and the yield per mu was increased by 3.2% - 12.7% when the soybeans being applied PGPR were compared with the soybean being applied conventional fertilization. And except one sites yield was increased non - obviously beeause of cryogenic and drought , the rest several sites average yield was increased by 6.0% above. Among them, the average yield was increased by 9.0% through liquid seed dressing and the average yield was increased by 9.3% through solid seed dressing. Conclusion：Tbe field experiment results were consist with the plot test results. The experiment had be shown that the effect of soybeans was stable when PGPR was applied in soybeans , and the yield was increased remarkably. Therefore PGPR had value in the practical application.
