表 Please select and fill in the relevant technical information according to the following technical classifications for specific technologies.
Technical link Key technical points Implementation season / month 1. Site Selection The ideal locations for fish-scale pits are gently sloping lands where water runoff is a problem. The slope facilitates the capture of rainwater as it flows down. 2. Design and Digging The pits are dug in a pattern that resembles fish scales, with each "scale" or pit partially overlapping the next. This design helps to maximize water capture. The size of the pits can vary but typically, they are around 1-2 meters wide and 20-30 cm deep. 3. Soil and Water Conservation The excavated soil from the pits is often used to create small embankments downhill of each pit, further enhancing water retention. These embankments slow down runoff, allowing more time for water to infiltrate the soil. 4. Planting The pits can be directly planted with crops or trees that benefit from the increased soil moisture. Alternatively, they can be left to naturally regenerate with local vegetation, improving biodiversity.
