Inlfuences of sod culture on soil physical and chemical characteristics of Camellia oleifera forest
In order to explore a new soil improvement model of Camellia oleifera forest, effects of sod culture on soil physical and chemical characteristics of C. oleifera forest were researched. The results show that sod culture had the functions of adjusting soil temperature, increasing soil temperature over 1℃in Spring, decreasing 12.5℃in Summer and greatly decreasing appearing frequency of high soil temperature. Sod culture benefits keeping soil moisture, especially in July and August of lacking of rainfall in southern region of China, and it can increase water storage of 0-20 cm, 20-40 cm and 40-60 cm soil layers by 15.90%, 7.14%and 2.78%respectively. In addition, sod culture can not only decrease soil bulk density and increase soil porosity and ifeld moisture capacity, but also increase the contents of soil organic matter, available P and available K in C. oleifera forest soil.
