Novel method for planting fungus grass to treat collapsing hill

Abstract

The invention discloses a novel method for planting fungus grass to treat a collapsing hill, and belongs to a collapsing hill biological treatment method. According to the invention, the technical scheme is as follows: through the adoption of a method for comprehensively treating the collapsing hill by planting or transplanting fungus grass seedlings, a drainage ditch and a surface covering net are arranged on the top surface of the collapsing hill; broadleaf paspalums are planted on the top surface of a slope crest; giant fungus grasses are planted on the wall of the collapsing hill; No. 1 oasis and giant fungus grasses are transplanted at the ditch bottom of the collapsing hill; 2 m high giant fungus grass seedlings are planted in groups on an alluvial fan; and No. 1 oasis in not less than three lines are planted at the edge of the alluvial fan, so as to form a green fence. The fungus grass treatment technology disclosed by the invention can be used for treating collapsing gaps, collapsing walls, collapsing slope crest surfaces and the like by different modes. According to the invention, the planted fungus grasses and so on can be used as raw materials for planting edible fungus and medicinal fungus and can be directly used as feeds for cattle, sheep, rabbits, pigs and the like; the feeding cost is reduced; a water and soil conservation effect can be achieved; and ecological benefits of soil erosion treatment are combined with economic benefits in aspects of plantation of the edible fungus and the medicinal fungus, breeding industry and the like.

Description

technical field [0001] The invention relates to a biological treatment method for collapsed hillocks, in particular to a new method for treating collapsed hillocks by planting Juncao, Oasis No. 1 and the like. Background technique [0002] Collapse refers to the erosion phenomenon in which the hillside is damaged and collapsed and scoured under the action of water force and gravity. The hazards of collapsing and erosion are second only to landslides and debris flows. [0003] The occurrence and development of collapsing erosion is the result that the erosive force of rainfall splash, runoff, gravity, etc. is greater than the erosion resistance of soil. The size of erosion and corrosion resistance is affected and restricted by various natural and human factors. Among all the natural factors that form collapsed hills, the destruction of vegetation is the main cause of soil erosion, while the human impact is to aggravate the destruction of vegetation. There are 239,100 large...

AI Technical Summary

Problems solved by technology

However, there are currently three problems in the treatment of collapsing hillocks. The first method uses engineering treatment methods, which require large investment and high cost; the second ecological treatment method involves planting fruits and tea, but the disadvantage is that although planting tea fruits has economic and ecological benefits , but it takes a long time and the effect is slow. It takes two to three years to take effect, and the treatment cost is relatively high. A sapling costs tens to hundreds of yuan; Ecological benefits, poor economic benefits

[0007] Retrieval of related materials, including Chinese patents, shows that there is no relevant report on the use of Juncao to treat collapse.
