2.1 技术简介

技术定义:

Gully healing using bananas as barriers

2.2 技术的详细说明

说明:

Gully pits (2'*2'*2') are dug across the gully. Smaller pits are dug in the bigger ones. Manure is filled in the smaller ones. Bananas are planted in the pits. Trash is filled in the bigger pits. A trash line is dug and supported by pegs. The speed of the runoff is lowered by the pits and trashline. The plants regenerate in the gully.
