摘 要：
为了验证甘肃省农科院土壤肥料与节水农业研究所微生物研究室研制的三种微生物肥料(生物氮肥、生物磷肥、复合菌肥)的肥效,通过大田试验,对它们在春小麦上的应用效果进行研究,结果表明,生物氮肥在替代一半化学氮肥时,春小麦籽粒和生物产量高于同量化肥和载体配施处理11.77%和12.42%,同时穗粒数增加13.80%,穗长增加6.20%,养分累积量提高17.38%~25.37%,与全量化肥配施时对春小麦产量无明显影响,但是可以提高养分累积量4.78%~14.30%。生物磷肥和复合菌肥与半量和全量化肥配施时,对春小麦增产效果不明显,但是生物磷肥与半量化学磷肥配施时,可以提高春小麦养分累积量4.03%~6.04%,与全量化肥配施时只对全磷的累积具有促进作用,而复合菌肥对春小麦的养分累积无明显影响。说明在供试的三种微生物肥料中,生物氮肥对春小麦产量和养分累积具有较强的促进作用,而且与半量化肥配施要优于与全量化肥配施,而生物磷肥和复合菌肥在春小麦上的应用效果不佳。

摘 要：
The application effects of three microbial fertilizers(biological nitrogen fertilizer,biological phosphate fertilizer and compound bacterial fertilizer),developed by microbial research room,institute of soil,fertilizer and water saving agricultural,Gansu academy of agricultural sciences,were studied on spring wheat through field experiment.The results showed that when biological nitrogen fertilizer substituted for a half amount of nitrogen fertilizer,the grain yield and biomass of spring wheat was significantly higher than application of the same amount of fertilize combined with the carrier by 11.77% and 12.42%,while the grain yield,biomass,grain number per panicle,panicle length,nutrients accumulation increased by 13.80%,6.20% and 17.38%～25.37%,respectively.Application of biological nitrogen fertilizer combined with full amount of fertilizer had no obvious effect on yield of spring wheat,but the accumulation of nutrients of spring wheat increased by 4.78% to 14.30%.Biological phosphate fertilizer and compound bacterial fertilizer combined with a half amount of fertilizer or full amount of fertilizer had no obvious effect on increasing spring wheat yield.Biological phosphate fertilizer combined with a half amount of phosphate fertilizer increased the accumulation of nutrients of spring wheat by 4.03% to 6.04%,and biological phosphate fertilizer combined with a full amount of fertilizer increased total phosphorus accumulation.Compound bacterial fertilizer had no obvious effect on the accumulation of nutrients.It is showed that biological nitrogen fertilizer had stronger role on the nutrients accumulation and yield of spring wheat,and it with a half amount of fertilizer combined application was better than with the full amount of fertilizer,while biological phosphate fertilizer and compound bacterial fertilizer had poor application effect on spring wheat.
