Abstract: Research on the soil microbe population and enzymes activities in greenhouse in Jinnan area, the result shows that the soil microbe amount was increased from northern to southern, the urease activities was higher as planting went on, and catalase activities has been remained stably at different planting years. The relative between microbe total and soil organic matter was plus correlation, but an upward trend that microbe amount was greater than organic matter content. This was a reason that the soil organic matter was lower.
