Abstract

Abstract: Through field investigation and laboratory analysis, soil aggregates stability in tea field was studied by Le Bissonnais method. Results showed that (1) the mass percentage of >5 mm soil aggregates expressed as wet stirring treatment (81.05%-95.62%)> slow wetting treatment (64.18%-89.31%)> fast wetting treatment (17.62%-24.26%) under different tea field age, and values of mean weight diameter (MWD), geometric mean diameter (GMD) and bias coefficient (C_S) of soil aggregates showed the same variation. The primary destructive mechanism of tea field soil aggregates was dissipation and fast wetting treatment was closer to the actual situation of tea field soil. (2) Stability of soil aggregates in response to continuous cropping of tea was significantly different under fast wetting treatment. Along with the increasing of planting age of the tea field values of soil aggregates MWD, GMD and C_S displayed a falling-and-rising trend, and lower values were found in tea fields with 23 years of age and showed that field soil aggregates stability was weakest in tea field with 23 years of age. (3) The stability of soil aggregates in tea field showed a positive correlation with contents of soil organic matter and clay under fast wetting treatment. The increased contents of soil organic matter and clay were beneficial to formation of soil aggregates and improved to stability of soil aggregates. Therefore, in management of tea fields, it is essential to increase the amount of straw covering the soil, so as to weaken the role of dissipation on soil aggregates disintegration, and in tea fields with 16 to 23 years of age, it was necessary to apply to use organic manure, so as to improve the stability of soil aggregates.
