摘　　要：当土壤砷含量达到一定浓度时,会对作物产生一定的毒害作用。运用盆栽试验和实验分析的方法,研究了土壤砷污染对桑树品质的影响,结果表明,随着砷质量浓度增加,桑叶叶绿素含量先降后升,影响不明显,而可溶性糖含量先上升后下降,影响显著。并探讨了砷污染防治途径,以期为无砷污染的生产提供参考。The soil is major natural resources which is indispensable to humanity, also, it is the vital component of environment and the basement of community. When the As contained in soil attains the certain density, it will threat to crop. Through the potted plant experiment and the empirical analysis, the influence of Ason mulberry tree＇s quality, and the protective technique in order to for without arsenic production provide suggestions.
