Abstract:: In order to explore the influences of tea plantation reclamation on soil properties, and promote coordinated development with economy and soil and water conservation in mountainous, soil physical properties and aggregate characteristics of different cultivate patterns in Yunwu tea plantation were analyzed. Results showed that the clay, porosity and capillary water capacity of tea garden soil manifested as a trend of decreases and then increases with the extension of the tea planting years compared with that of shrub land soil. Soil physical structure has been improved with soil bulk density reduction. Particle size greater than 5mm in the proportion of non-water-stable aggregates was 43.45%, others were bellow 20%. The longer the planting years were, the higher the proportion of non-water stable aggregates was. The proportion of non-water-stable aggregates was higher in cross slope planting pattern than that in discrete planting pattern. Particle size less than 2mm in the proportion of water stable aggregates exceeded 70%, and the damage rate of soil structure was less than 20%. Results also indicated the higher damage rates of soil structure in steep slope planting tea gardens and new planting tea gardens than that in other planting patterns, and also, discrete planting pattern had higher damage rate of soil structure than cross slope planting pattern. Planting tea plantation in mountainous was good for improving soil structure and properties.
