2. SLM技术的说明
2.1 技术简介
技术定义:
Contour terrace protection with front bank and three ditches in orchard rehabilitation.
2.2 技术的详细说明
说明:
There is sufficient rainfall in this area and runoff often destroys the existing terraces causing much cost for maintaining. Sluice system on the terraces is important. This technology of the contour terrace protection is to build front bank and three ditches on terraces in order to solve this problem. The method is that building front bank on a terrace edge and digging a ditch on the back terrace as well as digging a ditch upright the terrace along a relatively low rill to induct overflow out.
