Abstract:  In the present study, 3 treatments including continuous drought (control), fully wettish and water logging cultivation were set, and after these treatments, 2 crops of pakchoi were cultivated in the greenhouse. Soil EC value, NO-3 content and soil enzyme activity in different soil layers before and after pakchoi cultivation were tested and analyzed, respectively, to compare the effect of fully wettish and water logging cultivation on greenhouse soil salinization. It was shown that there was no significant difference in pakchoi yield by two water\|cultivation treatments. Soil EC value and NO-3 content in different soil layers under 2 water\|cultivation treatments were all smaller than the control. After cultivation of pakchoi, the soil EC value in 0-10 cm soil layer was increased by 83.66%, 48.88%, respectively, under fully wettish and water logging, while it was increased by 105.76% under control. Similarly, soil NO3- content in 0-10 cm soil layer after pakchoi cultivation was increased by 27.70%, 42.95%, respectively, under fully wettish and water logging, while it was increased by 98.83% under control. All these results suggested that two water\|cultivation treatments were effective in delaying salinization under greenhouse.
