Embodiment

[0037] Embodiment: A kind of purple soil difficult afforestation sloping land vegetation restoration technology, from the winter of 2015 to the spring of 2016, with the traditional vegetation restoration afforestation technology as contrast, in Lijia Village, Changtang, Leiyang City, Hengyang (East longitude 112 ° 47 ', north latitude 26 ° 36') The purple soil hilly slope land implements the vegetation restoration technology, with an area of ​​100 mu, and afforestation quadrats are set, and the area of ​​each quadrat is 30m×24m. This vegetation restoration technique includes the following steps:

[0038] a. Soil preparation: dig the planting hole, separate the topsoil layer and the subsoil layer on both sides of the planting hole;

[0039] b. Application of soil improvement substrate: The soil improvement substrate includes foreign soil, organic fertilizer and organic debris. Before planting seedlings, pour the foreign soil, organic fertilizer and debris into the planting hole...

Abstract

The invention discloses a vegetation recovery technology of a purple soil slope with difficulty in forestation, and belongs to the technical field of vegetation recovery. The vegetation recovery technology includes the steps: land preparation: digging a planting hole and separately placing a surface soil layer and a bottom soil layer on two sides of the planting hole; applying soil improvement substrates comprising earth removed from some other place to improve the local soil, organic fertilizers and organic fragments; seedling root system treatment: soaking seedling root systems in pond sludge or yellow mud after seedling taking and before planting, and binding seedling roots with plastic bags; plantation: planting seedlings into the planting hole, avoiding contact of the seedling root systems and the organic fertilizers in the seedling plantation process, stacking surface soil of the planting hole into a semicircular 'small cofferdam' with an upward opening after plantation; applyingsoil water-retaining agents: uniformly irrigating the semicircular 'small cofferdam' on the surface of the planting hole with root colonization water containing the soil water-retaining agents: tending and management. The vegetation recovery technology solves the problems that the purple soil slope is high in transformation difficulty, and vegetation forestation recovery is extremely difficult.

Description

technical field [0001] The invention relates to the technical field of vegetation restoration, more specifically, it relates to a vegetation restoration technology on purple soil difficult afforestation slopes. Background technique [0002] (1) Purple soil area [0003] The total area of ​​purple soil in Hunan Province is 1.3187 million hectares, accounting for 6.22% of the total area of ​​the province. Among them, the Hengyang purple soil slope covers an area of ​​162,500 hectares, accounting for 14.03% of the city's soil area. It is the area with the largest distribution of purple soil in Hunan Province, one of the areas with the worst ecological environment in Hunan Province, and a very representative area in southern China. Areas prone to ecological disasters. [0004] (2) Vegetation status [0005] Affected by geographical location and climate, the purple soil slopes suffer from serious soil erosion and exposed bedrock. In some areas there is almost no soil developme...
