微生物肥对小麦产量、赤霉病以及土壤养分的影响

Effects of Microbial Fertilizer on Wheat Yield,Fusarium Head Blight,and Soil Nutrients

为探讨微生物肥对小麦产量的影响、对赤霉病的防控作用以及对土壤理化性状的改良作用,以扬麦20为供试材料,进行“金菌冠”微生物肥不同用量(0、600、900、1200、1500、1800 kg/hm^(2))的配合处理试验。结果显示:施用微生物肥可以显著增加冬小麦的产量,施用量为1500 kg/hm^(2)时,小麦产量最高,增产达10.37%;对赤霉病也有一定的防治效果,防效可达52.54%。与常规施肥相比,增施该肥后土壤有机质含量(质量分数,下同)提高1.44%~9.80%,碱解氮含量提高4.42%~13.42%,有效磷含量提高5.33%~28.40%,速效钾含量提高4.79%~21.92%,pH值降低2.94%~5.70%。

In order to explore the effects of microbial fertilizer on wheat yield,the prevention and control of fusarium head blight,and soil physical and chemical properties,a field experiment was carried out,consisting of treatments with the microbial fertilizer Jinjunguan applied at different rates(0,600,900,1200,1500,1800 kg/hm^(2)).The results showed that the application of the microbial fertilizer significantly increased the yield of winter wheat.When the application rate was at 1500 kg/hm^(2),the yield was the highest,with an increase of 10.37%relative to the control without the microbial fertilizer.The fertilizer also showed noticeable control effect on fusarium head blight,whose control efficacy reached 52.54%.Compared with the conventional fertilization,the treatments with the microbial fertilizer increased the content of soil organic matter by 1.44%~9.80%,the content of alkali hydrolyzable nitrogen by 4.42%~13.42%,the content of available phosphorus by 5.33%~28.40%,the content of available potassium by 4.79%~21.92%;and decreased pH value by 2.94%~5.70%.
