| 摘 要： | 为了比较充分湿润栽培与淹水栽培对设施土壤盐渍化的延缓效果，在大棚内用封底塑料栽培桶，以连续旱栽为对照，充分湿润与淹水栽培处理后断水降渍，再接种2茬小白菜，比较各处理在小白菜茬口前后不同土层的土壤EC值、NO-3含量及酶活性。结果表明，两种水作处理的小白菜产量差异不显著。小白菜茬口前后土壤EC值、NO-3含量低于连续旱栽。小白菜茬口后与处理前相比，充分湿润与淹水栽培处理的土壤EC值在0-10 cm土层有所上升，增幅分别为83.66%，48.88%，而连续旱栽处理的0-10 cm土层土壤EC值增幅达105.76%；充分湿润与淹水栽培处理的0-10 cm土层，在小白菜茬口后土壤NO-3含量与处理前相比，上升幅度分别为27.70%，42.95%，而常规旱栽上升幅度达98.83%，说明两种水作处理对土壤盐渍化均有较好的延缓作用。

| 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. |
