光合细菌肥料在玉米上的肥效研究

光合细菌肥料在玉米上具有一定的施用效果,供试菌株有22.2％的纯培养物增产显著。不同剂型,增产效果不同,磁性菌剂在盆栽条件下,增产30.1％,大田为10.3％,普通菌剂分别是26.3％与7.9％。增产原因主要是提高玉米的根际固氮效应和叶绿素含量,增加穗粒的整齐度与出子率。

The Fertilizer Efficiency of Photosynthetic Bacterial Manure on Corn

Results showed that photosynthetic bacterial manure took certain effect on corn. The pure cultural bodies of increasing corn yield notably reached 22.2% in the experimental strains. The effect of yield for the variant bacterial manure was also different. The yield of inoculation magnetic bacterial manure was increased by 30.1% under pot experiment and by 10.3% in the field condition, but the yields of inoculating general bacterial manure were increased by respectively 26.3% and 7.9%. The main reason for increasing the yield was that the rhizosphere N_2—fixation effect and chlorophyll contain were raised and the neat level and ratio of ear grain were increased.
