摘要
为了解集约化经营雷竹栽培过程中土壤化学、生物化学性质和重金属含量的变化,分析了不同栽培历史的雷竹林土壤。结果表明:随着雷竹栽种历史的延长,土壤性质发生了明显变化。主要是:①土壤有机质含量增加,碳氮比升高,土壤磷素高水平积累;②土壤过氧化氢酶和磷酸酶活性呈明显下降趋势;③土壤中重金属锌、铜和铅含量有增加的趋势,在土壤中活动性明显增加。
Soils under Phyllostachys praecox stands with different cultivation histories are selected to study their content changes in chemical proprties and heavy metal elements.The findings show that with the prolonging history of Phyllostachys praecox cultivation,the properties of soil have changed greatly.①The content of organic matter and the ratio of C/N in soil increase,and phosphor is accumulated greatly;②The activities of hydrogen preoxidase and phosphatase in soil decline sharply;③The contents of heavy metal elements such as Zn,Cu and Pb in soil tend to increase and they become more active.[Ch,3 tab.11 ref.]
