2种农用微生物菌剂在小麦上的应用试验

A Preliminary Study of the Effects of Agricultural Microbial Agents on Wheat Agronomic Traits and Yield

通过研究农用微生物菌剂在小麦上的应用效果,为肥料登记和大面积推广应用提供依据。对喷施2个农用微生物菌剂的淮麦33农艺性状和产量进行分析研究,结果表明:小麦喷施2种微生物菌剂均能增加小麦每穗粒数,提高千粒质量,增加小麦产量,较常规对照(CK_0)分别增产28.89、22.23 kg/667 m^2,增产率分别为8.12%、6.25%,且分别达极显著水平(P<0.01)和显著水平(P<0.05);小麦喷施农用微生物菌剂1较清水对照(CK_1)增产22.22 kg/667 m^2,增6.13%,达显著水平(P<0.05);小麦喷施农用微生物菌剂2较清水对照(CK_2)增产20.0 kg/667 m^2,增5.59%,产量差异达显著水平(P<0.05)。

The current research assessed the effects of agricultural microbial agents on wheat agronomic traits and yield,so as to provide a basis for the registration and commercialization of microbial fertilizers. A field trial was conducted to evaluate the agronomic traits and yield of Huai Wheat 33,which were applied with two different agricultural microbial agents（ No. 1 and 2） as foliar sprays.The results indicated that foliar spray applications of the two agents increased the grain number per panicle,1000- grain weight,and yield of the tested wheat variety. Compared with the conventional control CK0,microbial agents No. 1 and No. 2 increased wheat yield by 28. 89 and 22. 23 kg / acre,respectively,whose increase percentages stood at 8. 12 and 6. 25,respectively,reaching a extremely significant level（ P〈 0. 01） and a significant level（ P 〈0. 05）,respectively. Microbial agent No. 1 elevated wheat yield by 22. 22kg（ 6. 13%） compared with the water control group CK1,reaching a significant level（ P 〈0. 05）; microbial agent No. 2 improved the yield by 20. 0kg（ 5. 59%） relative to the water control group CK2,reaching a significant level（ P〈 0. 01）. These agents could provide wheat with nutrition and thus increased its yield.
