Embodiment 1

[0030] A method for ecological restoration of rocky desertified mountains, comprising the following steps:

[0031] (1) Select the mountains of the Salaxi karst plateau mountainous light-moderate rocky desertification comprehensive control demonstration area in Bijie, design the blocking ditch according to the mountain topography, and choose the method of excavation or stacking to set up the blocking ditch. Ladder-shaped setting, ditch width 0.8m, ditch depth 1.2m, using artificial backfill or natural flow to fill the blocking ditch with soil, the filled soil accounts for 70% of the blocking ditch volume;

[0032] (2) Spread farmyard manure after filling the soil in the blocking ditch. The farmyard manure is a mixture of local river silt, crop stalks, livestock manure and litter. The farmyard manure is plowed under the soil, and then Plant sand pear and ryegrass in the blocking ditch, the planting distance of sand pear is 1.2m, and the planting density of ryegrass is 15kg / mu; ...

Embodiment 2

[0037] A method for ecological restoration of rocky desertified mountains, comprising the following steps:

[0038] (1) Select the mountains of the Salaxi karst plateau mountainous light-moderate rocky desertification comprehensive control demonstration area in Bijie, design the blocking ditch according to the mountain topography, and choose the method of excavation or stacking to set up the blocking ditch. Ladder-shaped setting, the ditch width is 0.6m, and the ditch depth is 1.2m. Artificial backfill or natural flow is used to fill the blocking ditch with soil, and the filled soil accounts for 80% of the blocking ditch volume;

[0039] (2) Spread farmyard manure after filling the soil in the blocking ditch. The farmyard manure is a mixture of local river silt, crop stalks, livestock manure and litter. The farmyard manure is plowed under the soil, and then Plant mulberry and alfalfa in the blocking ditch, the planting distance of mulberry is 1m, and the planting density of al...

[0044] A method for ecological restoration of rocky desertified mountains, comprising the following steps:

[0045] (1) Select the mountains in the light-moderate rocky desertification comprehensive control demonstration area of ​​the Salaxi karst plateau in Bijie, design the blocking ditch according to the mountain topography, and choose the method of excavation or stacking to set up the blocking ditch. Ladder-shaped setting, the ditch width is 0.8m, and the ditch depth is 1m. Artificial backfill or natural flow is used to fill the blocking ditch with soil, and the filled soil accounts for 60% of the blocking ditch volume;

[0046] (2) Spread farmyard manure after filling the soil in the blocking ditch. The farmyard manure is a mixture of local river silt, crop stalks, livestock manure and litter. The farmyard manure is plowed under the soil, and then Plant walnuts and red clover in the blocking ditch, the walnut planting distance is 1.5m, and the red clover planting density is...

Abstract

The invention provides an ecological remediation method of mountainous regions having rocky desertification. The ecological remediation method comprises the following steps of (1) arranging flow blocking channels, and stuffing soil in the flow blocking channels; (2) after the soil is stuffed in the flow choking channels, applying and sprinkling farmyard manure, and planting perennial waterloggingresistant fruit trees and pasture in the flow blocking channels; (3) planting liana at mountainous region areas between the flow blocking channels; (4) taking out soil accumulated in the flow blockingchannels, mixing the taken-out soil with weathered bacteria, performing uniform stirring to obtain a mixture, and then uniformly throwing and spraying the mixture to the mountainous region areas between the flow blocking channels; and (5) regularly collecting and resowing commercial crops, and performing proper conservation until soil fertility is thoroughly remedied and soil rocky desertification disappears. According to the ecological remediation method of mountainous regions having rocky desertification disclosed by the invention, the ecological environment of areas having rocky desertification can be remedied, and the economic benefits of the areas having rocky desertification can be promoted; and through the ecological remediation method for rocky desertification, fusion and development of ecology and economy are realized.

Description

technical field [0001] The invention relates to the technical field of rocky desertification control, in particular to a method for ecological restoration of rocky desertification mountainous areas. Background technique [0002] Rocky desertification is also called rocky desertification. It refers to the phenomenon of loss of surface soil, bare bedrock, loss of agricultural use value of land and degradation of ecological environment due to soil erosion. Rocky desertification mostly occurs in limestone areas, where the thickness of the soil layer is thin (mostly less than 10cm), and the surface presents an evolution process of gradually exposing rocks similar to desert landscapes. In terms of causes, the main factor leading to rocky desertification is human activities. Due to the continuous destruction of natural vegetation for a long time, large areas of steep slopes have been reclaimed, resulting in exposed ground, coupled with thin soil layers in karst rocky mountainous ...
