2.1 技术简介

技术定义:

Stone bund is an enbankment of stone constructed acrros the slope following the contour.

2.2 技术的详细说明

说明:

It is a stone wall stablized with grasses and fodder plant species. Its main purpose is moisture harvesting and soil erosion control. Establishment is made first by laying out contour lines, digging foundation and placing of stones in a manner to interlock to each other. Stone bunds placed on contour are known as level stone bunds. The purpose is to arrest runoff and enhance soil moisture to increaseavailability of water to plants. It is also aimed at controlling soil erosion from cultivated fields such that the plants have sufficient soil depth to establish and grow. Maintenance is done every year especially before thev rains. Maintenance continues for several years until the slope of the terraced land forms nearly level bench or slightly sloping outward terrace. The technology is suitable to semi-arid and arid climatic conditions having steep to very steep cultivated lands. It is suitable to major annual cereal crops, perennial crops, fruit trees and cash crops.
