Method for conducting rapid restoration of sand dune bare wound surface based on organic mixture

Abstract

The invention relates to a method for conducting rapid restoration of a sand dune bare wound surface based on an organic mixture. According to the method for conducting rapid restoration of the sand dune bare wound surface based on the organic mixture, an orientated cultivation technique for efficient fibrinolysis microflorae, an organic mixture fermentation and preparation technique, a mixture broadcast sowing technique and a sand dune bare wound surface restoring technique are integrated. The organic mixture with a certain water-retaining property and the viscidity is prepared by fully utilizing agriculture and animal husbandry production residues, the organic mixture is sprayed on the sand dune bare wound surface, then seeds of sand binding plants such as the artemisia halodendron are sown on the sand dune bare wound surface, sand crusts can be generated rapidly through artificial induction, a shrub-grass-crust sand binding system is established on the sand dune bare wound surface step by step, and thus continuous and stable restoration of degraded sand land is promoted.

Description

technical field [0001] The invention relates to the field of desert control, in particular to a method for rapid repair of sand dune exposed wounds based on an organic mixture. Background technique [0002] Sand dune fixation generally adopts the method of combining grass grid sand barriers and vegetation fixation. First, grass grid sand barriers are set to reduce wind and sand flow, and then trees or shrubs are planted to gradually form plant sand barriers to achieve the effect of windbreak and sand fixation. However, this method takes a long time and has a slow effect, and the survival rate of the planted trees and shrubs is low, and at the same time, it has a destructive effect on the soil surface when the grass grid is set and the plants are planted. Some methods of mulching and spraying sand-fixing glue can achieve fast and effective sand-fixing effects. However, these methods have the risk of secondary pollution, which poses a threat to the long-term stable restoration...

However, this method takes a long time and has a slow effect, and the survival rate of the planted trees and shrubs is low. At the same time, it has a destructive effect on the soil surface when setting grass squares and planting plants.

Some methods of mulching and spraying sand-fixing glue can achieve fast and effective sand-fixing effects. However, these methods have the risk of secondary pollution, which poses a threat to the long-term stable restoration of soil and vegetation, and is not sustainable
