Chinese Abstract

采用“留桩护坎”更新改植坡地老茶园,探讨控制径流减少新茶园土壤侵蚀量。试验结果显示,不同改植模式茶园土壤侵蚀量差异达到极显著水平。常规改植法因径流所致新茶园土壤侵蚀量为22.678t/km^2•a,“留桩护坎”比常规改植法减少土壤侵蚀量46.67%,不仅降低幼龄茶园砌坎保土的生产成本,护坎老茶树生物量产出,还起到“以旧养新”的目的。

English Abstract

The studies on adapting 'keeps the stakes to protect the ridge' to replant the old sloping tea garden were carried out, and controlling surface runoff to reduce the new tea garden soil erosion was discussed. The results showed that the soil erosion quantities of different replanting patterns tea garden differences reached to the limit significant level. The soil erosion quantity of the conventional replanting pattern new tea garden was 22.678t/km^2•a. Compared with it, the 'keeps the stakes to protect the ridge' pattern's soil erosion quantity was reduced by 46.67%. It not only reduced the production cost of the new tea garden to build ridges to retain the soil, but also can utilize the old tea stakes biomass output to maintain the new tea garden development.
