2.1 技术简介

技术定义:

Interplanting plum, peach in the Longan orchard to conserve soil and water and improve soil fertility.

2.2 技术的详细说明

说明:

The technology is to interplant fruit trees in orchard so as to prevent water loss and soil erosion. To implement the project, local government gave financial support and SWC specialists gave technologically guide to local land users. The slope land in the hilly and mountain areas were constructed into terraces and plant trees in order to improve surface vegetation cover rate and reduce water and soil loss; the harvesting surplus rainfall in the raining season and irrigate the fruit trees in dry seasons.

3.1 该技术的主要目的

• 减少、预防、恢复土地退化

3.2 应用该技术的当前土地利用类型

注释:

Major land use problems (compiler’s opinion): The ground surface of the SWC application area did not plant grass and green manure. The soil in the mountaintop area is lean, where broadleaf forest could be planted.

Major land use problems (land users’ perception): Because the soil layer is thin and poor, the local farmers wouldn't like to invest in the area where water loss and soil erosion is serious.

Problems / comments regarding forest use: Commonly, supplementary planting of trees in the following Spring.
