The objective of this paper is to investigate the status of plastic greenhouse (PG) soil degradation in Shaanxi Province. 148 PGs in Shaanxi were chosen to conduct the questionnaire surveys on production and management. A total of 330 soil samples in PGs and open fields were collected, and soil pH, soil organic matter (SOM), electrical conductivity (EC), cation exchange capacity (CEC), total nitrogen (TN), total phosphorus (TP), total potassium (TK), bioavailable phosphorus (AvP), bioavailable potassium (AvK) and heavy metals were analyzed. Results showed that the mean value of pH in PG soil was lower than the level in open field soil, and PG soil planted over 10 years had the lowest pH. The mean value of EC in PG soil was much higher than the level in open field soil. The rations of N: P: K and AvP: AvK in PG soil were respectively higher than those levels in open field soil, showing nutrient imbalance of PG soil. Heavy metals accumulation was more serious in PG soil than in open field soil in northern Shaanxi and the middle of Shaanxi, especially Cd, Cu, and Zn. In conclusion, PG soil degradation is serious in Shaanxi Province. PG soil degradation is closely related to highly intensive agricultural input and yearly continuous cropping, thus, it is very urgent to adopt crop rotation and fallow systems to improve PG soil quality.
