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。
Effect of Artificial Ecological Communities on Physical and Chemical Properties of Tea Plantation Soils with Fixed Positioning Method. The results showed that artificial ecological community could improve the physicochemical properties of tea plantation soils. Compared with tea plantation alone, the water content of soil physical properties in the artificial ecological community increased by 36.57% and 13.50%, respectively, and the capillary water holding capacity increased by 28.2% and 7.2% respectively compared with the pure tea plantation so as to enhance the soil drought tolerance. High, bulk density lower than pure tea garden. The distribution of nutrient elements in tea plantation showed 0 ~ 20cm artificial ecological community tea garden> pure tea garden, 20 ~ 40cm pure tea garden> artificial ecological community tea garden, indicating that the nutrient elements in artificial ecological community tea garden had upward enrichment trend, Fertility levels have improved. In addition, this paper also discussed the artificial ecological community of tea plantation soil water and heat balance, soil biological information and other characteristics.
