Afforestation and soil preparation method for rocky barren mountains in semi-arid regions

Abstract

The invention relates to the technical field of afforestation and soil preparation and particularly relates to an afforestation and soil preparation method for rocky barren mountains in semi-arid regions. The method comprises the following steps of: digging trenches: digging the trenches around the mountain along the contour line of a slope and separating surface soil from subsoil; building soil dams: piling the soil dams by subsoil along the extending directions of the trenches at the lower edges of the trenches; surface soil backfill: backfilling the surface soil to the trenches; and planting hole setting: setting the planting holes according to plant spacing in the trenches and adding mixed soil mixed by carrying soil, subsoil and surface soil in the planting holes, wherein the mixing proportion is as follows: carrying soil: subsoil: surface soil=1:1:1. According to the afforestation and soil preparation method for rocky barren mountains in semi-arid regions provided by the invention, the trenches are dug around the mountain, so that the soil preparation extent is great, the site conditions are obviously improved, and the water collecting effect is further quite remarkable. By adding the carrying soil, the soil nutrient condition of the planting holes is greatly improved, and the survival rate of afforestation and the volume of forest tree growth are effectively improved.

Description

technical field [0001] The invention relates to the technical field of afforestation and land preparation, in particular to a method for afforestation and land preparation of rocky barren hills in semi-arid areas. Background technique [0002] The greening of barren hills is an important public welfare undertaking in my country. In recent years, with the emphasis and support of the country on this undertaking, most of the barren hills suitable for forests have been well greened, and the ecological environment has been significantly improved. At present, the remaining barren hills have relatively barren soil and are difficult to be afforested. Land preparation before afforestation is an important part of barren hill greening, and it is one of the important technical issues that affect the effectiveness of barren hill greening. The current afforestation and land preparation technology can no longer achieve the expected greening goals in barren hills with relatively barren soil...

Problems solved by technology

[0005] The purpose of the present invention is to provide a method for afforestation and land preparation of rocky barren hills in semi-arid areas, so as to solve the technical problems in the prior art that the afforestation effect of barren hill afforestation and land preparation is not obvious, and the site conditions have not been improved.
