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...

Abstract

The invention discloses a forage grass planting method for a rocky desert area. According to characteristics of the rocky desert area, through land rocky desertification grade classification, forage grass selection, land preparation, forage grass seed selection, seed processing, sowing time selection, sowing amount selection, sowing mode selection, post-sowing compression and a field management technology, scientific forage grass planting is achieved, high-yield forage grass planting is obtained, economic benefits are remarkable, the environment is greatly improved, the water and soil are preserved, the rock desertification environment is improved, the primary productivity of land can be maintained and effectively improved, the yields of forestry and animal husbandry are increased, and the income of farmers is increased; meanwhile, soil carbon sink can be effectively increased, and the environment quality is improved.

Description

technical field [0001] The invention belongs to the technical field of pasture planting and relates to a method for planting pasture in rocky desertification areas. Background technique [0002] The southwest karst area is the largest area among the world's three major karst contiguous areas, with the most fragile ecological environment, and the degree of rocky desertification is the most serious. Solving the problem of rocky desertification is one of the most urgent tasks in the entire karst mountain area. The problem of rocky desertification consists of two main aspects, one is the ecological environment, and the other is the social economy. The rocky desertification problem is mainly due to the blind and unreasonable development of the ecological environment by people with backward economy, which leads to the gradual deterioration of the ecological environment and finally hinders the development of social economy. Agriculture, grassland, forestry and grassland projects ...
