| 摘 要： | 通过田间定位试验,采用钙镁磷肥(G)、泥碳(P)、猪粪(M)、钙镁磷肥+泥碳(GP)、钙镁磷肥+猪粪(GM)等处理对福建省龙岩市新罗区特钢厂附近的污染田进行改良。试验表明,大部分处理能提高土壤的pH值;处理钙镁磷肥、钙镁磷肥+泥碳和钙镁磷肥+猪粪对提高作物产量均有显著效果;大部分处理能抑制水稻、花生对镉铅的吸收;说明通过调节土壤pH值,改变土壤重金属活性是有机-中性化改良技术的主要机理。

| Abstract: | The field plot experiments conducted on a Cd-Pb polluted soil with eight treatments nearby steel plant in Xinluo strict Longyan city, Fujian province. It showed: most treatment could improve the soil pH. Treatments G, GP, GM could significantly stimulate the growth of the paddy, peanut. Most treatment could significantly inhibit the uptake of the heavy metals in paddy and peanut. This experience showed that changing the available heavy metals in soil by adjusting soil pH was the main mechanism, and the organ-neutralization could inhibit the uptake of Cd, Pb and adjusting the soil nutrient. |
