Distribution Characteristics of Soil Aggregates and Organic Carbon in Tea Plantation
摘要
Abstract
Distribution of soil aggregates and organic carbon were analyzed in tea plantation through 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 all the two soil layers, accounting for 56. 57% and 69. 53% of all soil aggregate respectively. Mean weight diameter of soil aggregate in tea plantation was 1. 02 mm, which tended to increase with descending soil layers. Tea plantation soil aggregate ratio of organic carbon in 0. 25～0. 5 mm aggregate in 0—20 cm and <0. 25 mm aggregate in 20—40 cm were the highest and soil aggregate ratio of organic carbon in 2 —5 mm were the lowest for all the two soil layers. Tea plantation soil aggregate size of the distribution of the ratio of organic carbon 0—20 cm were higher than 20—40 cm soil layer.关键词
