光合细菌在农业上的应用研究

Research on the Application of PSB in Agriculture

采用专用培养基光照培养的紫色非硫细菌有 2 2 .2 %的纯培养物具有明显的增产作用 ,但以混合菌株制备的磁性菌剂与稀土菌剂的效果为好 ,在玉米和水稻上可增产 10 .3%± 2 .6 % ,在果菜上的效果更佳 ,还可抗病 (CMV)和改善果实品质。

The pure cultural bodies of the phodospirillaceae cultured under light had obvious yield increasing effect. The effects of magnetic bacterial manure and the PSB product included rare earth elements were good. The yield was increased by 10.3±2.6% on rice and corn. The PSB bio-fertilizer had better effect on trees and vegetables. PSB could also control plant diseases (CMV) and improve fruit quality.
