| 采用人工模拟降尘，以 4 种叶菜类蔬菜作物为材料，研究煤粉尘污染对蔬菜滞尘量、滞尘能力、叶
片生长和酶保护系统的影响。 结果表明：随着降尘量的增大，4 种叶菜类蔬菜的整株滞尘量和单位面积滞尘量
均增加，白菜和生菜的滞尘能力最强，其次为油菜，最小为菠菜；煤粉尘对油菜和菠菜的叶面积影响不大，对白
菜和生菜叶面积的影响表现为先促进后抑制。 煤粉尘促进了 4 种叶菜类蔬菜作物 SOD、POD 和 CAT 等酶活性
的增强，从酶促反映分析，白菜、油菜耐煤粉尘能力比生菜、菠菜强些，受害程度相对较轻。 综合分析，滞尘能力
越强，商品性越差，建议在日降尘量小于 3.75 g/m2
的地方，种植菠菜、油菜等滞尘能力较差的叶菜类蔬菜；在日
降尘量小于 2.50 g/m2
的地方可增加白菜、生菜等滞尘能力较强的叶菜类蔬菜。 |

| By artificial simulation dust-fall, with 4 kinds of leafy vegetable as material, the effects of coal dustpollution on the dust-retention quantity and ability, leaf growth and protective enzyme system were studied in thispaper. The results were as follows: with the increase of dust-fall amount, the dust-retention quantity of the wholeplant as well as the unit area of 4 kinds of leafy vegetables increased. The dust-retention ability of Chinese cabbageand lettuce were the strongest, followed by rape, spinach was the weakest. There was little effect of coal dust on theleaf area of rape and spinach, and the leaf area of Chinese cabbage and lettuce behaved promote first and theninhibit under simulated dust-fall. The SOD, POD and CAT activities of 4 kinds of leafy vegetables were inhancedunder dust-fall conditions, and the dust-resistence of Chinese cabbage and rape were stronger than lettuce andspinach. Comprehensive analysis, the stronger the dust-retention ability was, the worse the vegetable commodity was.Thus, its suggested that such leaf vegetable as spinach and rape should be planted in the place where coal dust-fallamount was less than 3.75 g/m2d, and spinach and rape should be planted in the place where the coal dust-fallamount was less than 2.50 g/m2d. |
