为探讨海泡石在Cd污染植烟土壤改良中的可行性，以恩施宣恩县晓关乡酸性土壤为供试土壤，通过人工模拟Cd污染，采用盆栽试验方法，研究了海泡石对烟叶Cd含量、植烟土壤Cd含量、烟株生长发育及烤后烟叶产质量的影响。结果表明，施用海泡石后，可有效提高植烟土壤pH值，降低土壤Cd活性，抑制烟株对土壤Cd的吸收。烤烟生长优势明显，叶长、叶宽均显著高于对照；烟叶的总糖和还原糖均较对照降低，而总氮，烟碱，钾和氯等则整体上表现为较对照增加的趋势。综合研究表明：盆栽酸性植烟土壤施加30%～40%海泡石后，可以达到改善土壤酸性环境，提高烟叶安全性和产量的三重功效。

Pot experiments were conducted to study amelioration effect of meerschaum in Cd contaminated tobacco soil through simulation. Results showed that meerschaum can effectively improved soil pH value, reduce Cd activity and refrain tobacco plant from absorbing Cd. It resulted in less total sugar and reducing sugar and more total nitrogen, nicotine, potassium and chlorine. It is concluded that soil acidic environment can be ameliorated if added with 30%~40% meerschaum, thus improving tobacco safety and productivity.
