化学改良剂对玉米、大豆生长及Pb、Cd的影响
hemical Improvement Influence to the Growth of Corn and Soy Bean and the Contents of Heavy Metal Pb、Cd
本文采用温室盆栽土培方法，研究几种化学改良材料（粉煤灰、腐殖酸、沸石、保水剂）及其复合在被重金属Pb、Cd污染土壤中（Pb≤150mg/kg、Cd≤10mg/kg），对玉米、大豆生长的影响及对Pb、Cd的固化效果。结果表明，在土壤中加入各种改良材料对玉米和大豆的生长有明显的促进效果，而且有效地对土壤中的重金属元素进行固化络合，大大降低了植物对土壤中重金属元素Pb、Cd的吸收。
his experiment uses the the method of the bonsai earth to cultivate in greenhouse, studies several chemically modified material(flyash、humic acid、zeolum、superabsorbent) and their compound influence to the growth of corn and soy bean and the solidified result of heavy metal Pb and Cd in the soil which polluted by heavy metal Pb and Cd(Pb≤150mg/kg、Cd≤10mg/kg). The result indicated, mixes in various meliorative material in the soil, it not only obviousiy promote the growth of corn and soy bean but also availably solidify heavy metal element in the soil, greatly decrease the heavy metal element Pb and Cd absorbed dose of plants in soil.
