摘　　要：坡地茶园土壤流失比较严重,特别是新植茶园。提高茶园土壤覆盖度是减少茶园土壤侵蚀的有效手段。重庆地区山地茶园实行坡改梯后,再配套绿肥等复合种植技术及开沟集中深度施入速效追肥技术,提高茶园覆盖度,可显著提高坡地茶园持续的保土保水保肥能力,其土壤年侵蚀量仅为64．3～174．2 kg／667 m3,是降低山地茶园土壤侵蚀,形成山地茶园生态栽培的有效模式。Soil erosion represents a serious problem in sloping tea gardens, especially in newly established tea gardens, Increasing vegetation coverage is an effective strategy to reduce soil erosion. In the experiment reported in this paper, an integrated strategy was adopted to combat soil erosion and satisfactory results were achieved. The measures included terracing, green manure crop planting, deep ditch digging and applying quick-acting fertilizer into the ditches. The annual loss of soil under this system was only 2 288 kg. hm^-2. a^-1.
