摘　　要：测定了湖北省潜江市高场示范区 7个不同渍害度稻田的土壤养分状况与微生物数量 ,经显著性测试及回归分析 ,结果表明涝渍稻田土壤微生物数量、土壤养分状况的垂直分布有一定差异性 。The microorganisms and nutrients in the soil of seven different waterlogged paddy were determined. By the analysis, the microorganisms and nutrients in the soil were rather different in different degree waterlogged paddy and soil depth, and their correlations were established,too.
