Distribution Characteristics of Soil Aggregates and Organic Carbon in Hill Tea Plantation
摘要
Abstract
Distribution of soil aggregates and organic carbon were analyzed in hill tea plantation by the methods of field investigation and laboratory analysis. The result indicated that the soil granule structure of tea plantation was dominated by >5 mm aggregate for 0 -20cm soil layers, accounting for 20. 59%, the soil granule structure of tea plantation was dominated by < 0. 25 mm aggregate for 20 - 40 cm soil layers, accounting for 35.32%. Tea plantation soil aggregate ratio of organic carbon in >5 mm were the highest for both 0 - 20 cm and 20 - 40 cm soil layers, and the content of organic carbon increased with increment of aggregate size. The reserve and distribution of the ratio of organic carbon in > 5 mm aggregate in 0 - 20 cm were the highest and in 0. 25 - 0. 5 mm were the lowest. On the contrary, the reserve and distribution of the ratio of organic carbon in 0. 25 -0. 5 mm aggregate in 20 - 40 cm were the highest and in >5 mm were the lowest.关键词
