2.1 技术简介

技术定义:

Stablized bund constructed fron stone and soils on the farm land along the contour and planted with multipurposive plant species

2.2 技术的详细说明

说明:

The stablized bund is constructed on farm land in order to reduce slope length, angle and there by control soil erosion and enhance moisture/water retention capacity of siols. The bund is established along the contour by digging trench/foundation and place stone walls on the excavated trench. It is stablized by planting grass. The structure is regularly maintained by repairing breaks. Some farmers put on additional height to the bunds as part of the upgrading practice. The technology is suitable to all agroecological conditions, where stones are available for construction.
