Funnel bottom fish-scale pit soil preparation technology

The invention relates to funnel bottom fish-scale pit soil preparation technology and belongs to the technical field of afforestation soil preparation. The funnel bottom fish-scale pit soil preparation technology is characterized in that semilunar pits are dug on a steep barren mountain slope from top to bottom along a contour line and arranged in the shape of a Chinese character 'pin', and a vertical side of each semilunar pit faces the upper portion of the barren mountain slope while a semilunar face of the same faces the lower portion of the barren mountain slope; one side of each semilunar is the vertical side, the side, close to the vertical side, of each semilunar is semilunar, each semilunar pit is a funnel bottom with a large upper opening and a small lower opening, is fish-scale-shaped and is called a funnel bottom fish-scale pit, soil preparation specification of each semilunar pit is width of the upper opening x longitudinal width x depth=100cmx80cmx60cm, and specific specification can be changed according to factors like seedling specification and site condition. The funnel bottom fish-scale pit soil preparation technology has certain water storing capacity, and retaining of soil, water and fertilizer can be realized when trees are planted in the pits.
