Contributions of Plant Litter Decomposition to Soil Nutrients in Ecological Tea Gardens

Plant litter decomposition and its effect on soil nutrients are important parts of the ecosystem material cycle, understanding these processes is key for species selection allocation to promote effective use in ecological tea gardens. In this study, situ method was used examine characteristics leaf Cinnamomum glanduliferum, Betula luminifera, Cunninghamia lanceolata, Pinus massoniana, Camellia sinensis prunings Jiu’an garden Guizhou their effects nutrients. The results showed that rate broad-leaved tree higher than coniferous species, with a half-life 1.11–1.75a turnover period 4.79–7.57a. There two release modes nutrient from litter: direct leaching–enrichment–release. Different litters make different contributions nutrients; luminifera glanduliferum increased contents organic carbon, total nitrogen, hydrolyzed nitrogen. content phosphorus, available potassium, massoniana potassium potassium; therefore, it concluded had positive content. Thus, good choice inclusion gardens increase return capacity, maintain fertility, generally development
