【摘要】 用平板菌落计数法分析了雷竹覆盖保护地土壤微生物数量。结果表明，使用有机物料覆盖的雷竹林地土壤的微生物数量显著增加。３个覆盖处理（竹叶、砻糠和稻草）林地微生物总数是对照的３０～６０倍，其中细菌增加幅度最大，竹叶和砻糠处理的变化幅度要明显大于稻草。更多还原

【Abstract】 Amount of soil microorganism in Lei bamboo forest of protected cultivation is studied by means of plate count.The results show that soil microorganism in quality increases in Lei bamboo forest mulched with organic materials.Amount of soil microorganism of three treatments with bamboo leaf,rice hull and rice straw is 30 to 60 times that of check.Bamboo leaf and rice hull are superior to rice straw,but all of them can lead to increase of soil microorganism,especially bacterial population.更多还原
