Abstract With the research on the soil in greenhouse with different planting years,the results showed that the soil soluble salt,available nutrient content and electrical conductivity increased with the prolonged period of planting,while the soil pH droped,the soil organic matter content did not go up much ,nitrate nitrogen in available nutrient was high,the available phosphorus in the soil was abundant. At the end,the measures on the improvement of soil fertility and management were recommended.
