摘要
南昌市区和郊区降水的酸雨频率在78.3%以上,各监测点 pH 均值在4.32～5.00之间;受酸雨影响的土壤重金属离子溶出增加,水稻减产约4%;提出了酸雨危害作物的防治对策。
The frequency of acid-rain in precipitation in both urban and suburb districtswas over 78.3%,The pH values from the monitoring points were between 4.23and 5.00.Influenced by the acidrain,the heavy metal ions increased in thesoil,and the rice output decreased by 4%.Countermeasures against it for theprotection of crops are given in the paper.
