是

2.1 技术简介

技术定义:

Trashlines are constructed as a barrier of runoff, soil erosion using maize, sorghum and teff straw/stalk

2.2 技术的详细说明

说明:

Trashlines are formed of sorghum, maize or teff straw placed in to form a rectangular basin. The main lines are constructed along the contour. The technique is multi purposive I.e. water harvesting, soil trapping, physical obstraction and improve soil fertility. The estabilishment is made by collecting the straws and then spread it on contour lines. The environment in relation to the technique is low and erratic forms of rainfall, high evapotranspiration, availability of straw.
