| 摘 要： | 通过模拟试验研究不同PH值的酸雨对小麦生长的影响,说明小麦遭受酸雨特别是高酸度酸雨后,小麦叶片可见明显伤害,酸雨使小麦叶片出现可见伤害(斑)的阈值是PH=3.0;对小麦株高、叶面积、含水量有一定的负作用;酸雨对小麦的胁迫效应随酸雨的氢离子浓度增大而显著,且与酸雨处理次数和处理量相关。旨在为山西省二氧化硫实施控制和小麦丰产优质种植提供依据。

| Abstract: | The article researches on the influence of acid rain with difference PH value on wheat growth by simulation experiment, and reaches the conclusions: After suffering the acid rain particularly high acid rain, the threshold value of the injury of wheat leaf is 3.0; Acid rain has certain negative effect on wheat height, leaf area and water content; The threatening effect of acid rain on wheat increases along with the increase of PH and is related to the handlingtimes and handling capacity of acid rain. It provides the basis for the control of sulfur dioxide and the high output and high quality of wheat in Shanxi Province. |
