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.

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.

If the original slope has changed as a result of the Technology, the slope today is (see figure below): 15.00%

Gradient along the rows / strips: 60.00%

Construction material (earth): cheaper, local materials, good effect

Slope (which determines the spacing indicated above): 28.00%

If the original slope has changed as a result of the Technology, the slope today is: 13.00%

Lateral gradient along the structure: 26.00%

For water harvesting: the ratio between the area where the harvested water is applied and the total area from which water is collected is: 1:2.00

4.7 影响成本的最重要因素

描述影响成本的最决定性因素:

Main factor influencing the SWC cost is steeper slope. Since the slope steeper is, much more cost needed to level off terrace. In some places, the earth needs to be moved from one place to another which will spend a lot of labor forces.
