摘要
采用定点定位方法进行人工生态群落对茶园土壤物理化学特性的影响研究。结果表明:人工生态群落能改善茶园土壤的物理化学性质。人工生态群落茶园土壤物理性状上下土层含水量分别较单纯茶园提高36.57%和13.50%,毛管持水量分别较单纯茶园提高28.2%和7.2%,从而增强土壤抗干旱能力,总孔隙度较单纯茶园高,容重较纯茶园低。茶园土壤营养元素分布表现为0～20cm的人工生态群落茶园>纯茶园的,而20～40cm纯茶园>人工生态群落茶园,表明人工生态群落茶园土壤营养元素有向上富集的趋势,对表层土的肥力水平有提高作用。另外本文还探讨了人工生态群落茶园土壤水热平衡作用,土壤生物信息等特征。
Long-term follow up monitoring program was carried out on soil physicol and chemical properties for tea plantation in Gui Zhou. It was found that, the soil physical and chemical properties for tea plantation was improved by artificial ecological community. The artificial ecological community of tea plantation improved water status of surface and sub soils.In addition,tea plantation enhanced the movement of nutrients to surface soil.
