Rocky desertification control method

Abstract

The invention discloses a rocky desertification control method. The rocky desertification control method comprises the steps that firstly, leucaena subspecies seeds are soaked, seedling is conducted through seedling-raising plates, and seedlings are transplanted to a barren mountain subjected to rocky desertification when growing to 10 cm; secondly, the seeds can sprout after being sown for 2-3 days, seedlings emerge 5-7 days later, and the seedlings are transplanted to the barren mountain subjected to rocky desertification when growing to 10 cm; thirdly, seedling groups are planted every 200 m, the elevation difference of the seedling groups is controlled to be about 5 m-30 m according to the terrain, each seedling group includes 5-20 leucaena subspecies seedlings, and the leucaena subspecies seedlings are spaced from one another by 10 cm; and fourthly, control and greening are conducted by combining self reproduction, continuous transplanting and manual seed sowing according to the site growing condition of the seedling groups. According to the rocky desertification control method, since the leucaena subspecies seeds have high drought tolerance and sprouting capacity, the leucaena subspecies seeds can grow in the barren mountain subjected to rocky desertification, and the leucaena subspecies seedlings have the characteristics of soil building capacity, rapid growth and the like; and the purpose of rocky desertification control is achieved through cultivation and self reproduction after seeds are sown and the leucaena subspecies seedlings are transplanted to an area subjected to rocky desertification.

Description

technical field [0001] The invention relates to the field of environmental management, in particular to a method for controlling rocky desertification. Background technique [0002] The area of ​​rocky desertification in Guizhou Province is 37,000 square kilometers, accounting for 18.79% of the province's land area. Special environmental and natural conditions combined with population overload, deforestation and other reasons lead to serious soil erosion and degradation of the ecological environment. Due to various effects, the rocky desertification in Guizhou is intensified, and it is urgent to control it. The current management methods are mainly closing mountains for afforestation, returning farmland to forests, planting forests and grasses, and water conservancy projects. However, there is no standard guidance for the selection of forest and grass, and no plant samples suitable for the karst environment and landform with low cost and high efficiency have been found. ...

Problems solved by technology

However, there is no standard guidance for the selected forest and grass. At present, no plant samples suitable for the karst environment and landform with low cost and high efficiency have been found. Conventional treatment methods make the treatment cost high, the treatment speed is slow, and the treatment effect and progress cannot be achieved. expected requirements
