"沃根菌"微生物菌剂对玉米生长和产量的影响

目的]研究"沃根菌"微生物菌剂对玉米生长和产量的影响。方法]试验采取随机区组对比方法,对玉米进行微生物菌剂和化肥减量田间试验。结果]当地常规施肥量+75 kg/hm~2固体微生物菌剂处理和当地常规施肥量减量20%+75 kg/hm~2固体微生物菌剂处理与对照相比,株高分别增加了0.9、0.3 cm,茎粗分别增加了0.3、0.2 cm,产量分别增加了7.4%和0.1%。结论]施用"沃根菌"微生物菌剂对玉米增产作用显著,用其替代20%化肥增产不显著,此外施用该菌剂对增加茎粗有显著作用。

Effect of "Wogenjun" Microbial Agent on Growth and Yield of Maize

Objective]To research the effect of "Wogenjun" microbial agent on growth and yield of maize.Method]Randomized comparison test was conducted to apply microbial agent and reduce fertilizer to field trials. Result] Compared with the control, the plant heights of conven-tional fertilization +75 kg/hm2 solid microbial agent treatment and conventional fertilization reduced by 20% +75 kg/hm2 solid microbial agent treatment were increased by 0.9,0.3 cm, the stem diameters were increased by 0.3,0.2 cm,and the yields were increased by 7.4%and 0.1%, respectively.Conclusion]The yield-improving effect of "Wogenjun" microbial agent to the maize yield was significant, but the effect of repla-cing 20% of fertilizer was not significant, in addition,the application of the microbial agent has significant effect on the stem diameter.
