Abstract：In order to clarify soil nutrient of vegetable-cultivated greenhouse in Tianzhen county of Shanxi,0-20 cm soil samples from 21 representative greenhouses were conducted using a S-sampling trip pattern with 5 sampling points,and the adjacent open field soil was used as control.The results indicated that pH value of vegetable-cultivated greenhouse was lower 1.5-2.5 than control (8.26),which showed a clearly acidification trend.Soil organic matter content was lower (15.41 g · kg 1),soil nutrients could not be effectively used.The content of soil total N was in the range of 0.4-0.6 g.kg-1,available P content was lower than 30 mg.kg-1,total N and available P contents were seriously deficient.Soil available K was more than 200 mg · kg-1 which exceeded the normal demand for crops,and we should control the amount of potash fertilizer application in the future.In short,vegetable-cultivated greenhouse unreasonable fertilization has led to significant differences in soil nutrient supply and vegetables demand.We should promote scientific fertilization in the future.
