Abstract:: Compared of soil nutrient and microbial community characteristic in soil of open field and greenhouse in Shengyang Liaoning province.The results showed that the accumulation of organic matter,total nitrogen，available nutrient in greenhouse were higher than that in open field,especially the available phosphorus and available potassium.Compared with Index of Protected Soil Fertility in Liaoning Province,the content of available nitrogen was in low level,while organic matter was in middle level，and total nitrogen,available phosphorus，available potassium were in high level.Compared with soil in open field,soil pH dropped in greenhouse.The more the soil in greenhouse used，the more acidifying.Soil microbial was given priority to bacteria in both two planting patterns.From the community structure，the ratio of soil bacteria to total microbial was decreased.,while the ratio of soil fungus or actinomyces was opposite.
