肥力高菌肥对油菜、小麦产量的影响

Effect on Yield of Rape and Wheat by Applying Feiligao, A Compound Nitrogen Fixation Bacterial Fertilizer

为探讨复合微生物固氮菌肥肥力高对油菜、小麦的施用效果及最佳施用方法 ,进行了不同肥力土壤、不同施用方式的试验。结果表明 :肥力高在油菜上有较明显的增产效果 ,增产幅度 6 .6 %～ 8.9% ,高肥力土壤的增产效果优于低肥力土壤 ;在小麦、油菜上的经济效益均高于施尿素。

The test of fertilizer effect was carried out in different fertility soils and in different application methods to investigate the fertilizer effect and optimum application method for rape and wheat by applying Feiligao, a compound nitrogen fixation bacterial fertilizer. The results show that the Feiligao has a siginificant increasing effect in the rape yield by 6.6%～8.9%, and the effect of increasing yield in the higher fertility soil is better than in the lower fertility soil, and that the economical benefits for both wheat and rape by applying Feiligao is higher than applying urea. The optimum application method is to dress with seed.
