| 中文摘要 |
| 采用模拟酸雨喷雾和SO2开顶式熏气,研究了酸雨和SO2复合作用对西红柿、胡萝卜和棉花等农作物产量的影响及其机理。通过模拟试验,发现酸雨和SO2使农作物生长受阻,产量降低,其二者的复合作用明显高于单一因素的作用,但其交互作用不显着。并通过模拟相关方程计算出农作物产量损失的污染物阀值。 |
| 英文摘要 |
| The effects of acid rain and sulphur dioxide alone and in combination on tomato,carrot and cotton was studied by simulated acid rain irrigating and SO2 exposure. It was found that the simulated acid rain and sulfur dioxide could inhibit the growth of crops in a degree and reduce the productivity. The synthetic effect of acid rain and sulfur dioxide was more notable than alone, but their mutual effect was not marked. |
