Embodiment 1
[0028] Embodiment 1: a kind of grass planting method in rocky desertification area, comprises the following steps:
[0029] (1) Classification of rocky desertification: according to 0.2km 2 Figure porphyry exposed rate, 0.2km 2 The situation of vegetation and soil coverage in the map is divided into grades of rocky desertification, and moderate karst rocky desertification is at 0.2km 2 Tu porphyry rock exposure rate is 51-70%, 0.2km 2 The coverage rate of vegetation and soil cover in the map spot is 49-30%. The rocky desertification is intensified, the soil erosion is serious, and the soil layer is shallow. Most of them are rocky slope farmland and sparse shrub grass slope, and the slope is relatively large (generally greater than 25°). Strongly disturbed by human activities, soil erosion is serious, and natural disasters in ecology and geology are frequent; in moderately rocky desertification areas, the ecological environment is fragile, the soil layer is shallow, and the v...
