    佛山云勇林场3种人工幼林的生长和土壤养分特征

    Growth and Soil Nutrient Characteristics of Three Young Plantation Types in Yunyong Forest Farm, Foshan

      摘要
    • 摘要: 对佛山云勇林场3种林分的生长和土壤养分进行了研究:用pH计测定土壤pH;有机质用重铬酸钾容量法-外加热法测定;水解性氮用碱解扩散法测定;速效磷以NaHCO3提取土样后,用钼蓝比色法测定;速效钾用醋酸钠浸提,原子吸收分光光度法测定.结果表明:常绿阔叶混交林的生长情况最好,土壤养分最高;各林地的土壤呈强酸性;土壤有机质、水解性氮和有效磷含量为常绿阔叶混交林地》常绿针阔混交林地》杉木林地,而有效钾含量为常绿阔叶混交林地》杉木林地》常绿针阔混交林地,表明常绿阔叶混交林显著地改善了林地养分状况,常绿针阔混交林对改善土壤养分也有一定的作用.各林地土壤的有机质和各种养分含量之间存在显著差异.
