摘　　要：研究结果表明,粉尘和 SO_2等的复合污染引起柑桔生长发育的一系列不良变化。光合作用受挫,呼吸作用亢进,开花数量少,座果率降低,正常果实减少17%-45%,同时,果实中有机酸含量增加,总糖含量降低,表现出甜度不足、酸度过重、口感不良的特点。严重影响桔树经营生产。The compound pollution of deposit, S02 and other pollutants from a po- wer plant to orange trees(Citrus spp.)was studied in this paperoThe pollut- ants inhibited t`hle photosynthesis, strengthened the inspiration, and hinde- red growth,bloom and setting,decreased the fertile fruits and economical output.Quality analysis of the fruits showed that the total sugar decreased, while organic acid increased.The compound pollution affected the manage- ment and economical income of orange trees.Some reasons of injury were also discussed in the paper.
