【摘要】 本试验将磷肥厂的底泥施用于棉花土培试验中,其结果显示:施用该种污泥能使蕾铃期棉花蕾中Cu、Zn、Cr及Pb的含量增加,并且棉花所吸收的Cd、Pb及Zn也主要集中在棉花叶片及蕾中,茎和柄中的含量很低;在收获期,施用污泥对棉花中各种重金属含量的影响都不是很大,相反还有促使这些重金属含量下降的趋势。表明污泥的短期施用对棉花不存在严重的重金属污染问题。更多还原

【Abstract】 The factory sludge was used in the cotton pot experiment and the result showed that: the use of sludge have no obvious effect on the concentrations of heavy metals in cotton either on the bud and boll stage or on the mature stage except the concentrations of Cu, Zn, Cr and Pb were increased. On the contrary, the use of sludge has the trend to decrease the concentrations of these heavy metals.The experiment showed that the use of sludge in short time have no danger of heavy metals pollution on the cotton growth.更多还原
