Problems solved by technology

[0006] The existing method of regreening in the sandstone area is mainly to plant Chinese pine and seabuckthorn in the soil-covered area, while the methods of regreening in the exposed sandstone area, sand-covered area, and soil-covered area are lacking.

preparation example Construction

[0031] In the present invention, the species of the moss includes P. erythrophyllum and / or P. apicophyllum. The source of the moss is not particularly limited in the present invention, and conventional sources can be used. In the present invention, when the mosses include P. borealis and P. apicophyllum, the present invention has no special limitation on the mixing quality of the two mosses, and any quality can be mixed. In the present invention, the preparation method of the moss preferably comprises: cultivating and propagating in a greenhouse to obtain the cultivating moss, placing the cultivating moss in a cool and ventilated place and then cutting to obtain the cut moss, and the cutting moss at 0-5 °C for 10 h to obtain mosses for planting. In the present invention, the length of the moss is preferably 5-8 mm. The invention makes the moss enter a dormant state by drying in the shade, reduces the metabolism of active cells in the moss, promotes the moss to secrete reprodu...

Abstract

The invention provides an establishment method for an ecological crust of vegetation degradation bare land, and belongs to the technical field of development and utilization of ecological agriculturalresources. The method comprises the steps: spraying a nutrition medium to an establishment region, mixing moss with a water-retaining material to obtain an establishment material, and spraying the establishment material onto the nutrition medium, wherein the moss includes didymodon fallax (Hedw.) zander and / or barbula constricta; the nutrition medium includes the components including a medium, athickening agent, a binder and a preservative; and the water-retaining material includes a water-retaining agent, a decomposable binder and a nutrition solution. According to the establishment method,the target moss is sprayed onto the nutrition medium after being evenly mixed with the water-retaining material, so that the survival rate of the moss crust can be greatly improved, the surface barearea of a vegetation degradation region is significantly reduced, the stability of surface water and soil is increased, and syngenesis from simple vegetation to complex vegetation in the bare land ispromoted to accelerate ecological restoration.

Description

technical field [0001] The invention belongs to the technical field of development and utilization of agricultural resources, and in particular relates to a method for establishing an ecological crust on degraded bare land. Background technique [0002] A large amount of arsenic sandstone is distributed in the bordering area of ​​Shanxi, Shaanxi and Mongolia in the northern Loess Plateau of my country, mainly in Dongsheng District, Zhungeer Banner, Yijinhuoluo Banner, Dalate Banner, and Hangjin Banner of Ordos City, Inner Mongolia Autonomous Region, and Shenmu Banner in Shaanxi Province. Two counties of Fugu, Hequ and Baode in Shanxi Province. The arsenic sandstone belongs to the continental clastic rock series. Although the color of the arsenic sandstone in different regions is different, there is no significant difference in the content of other minerals except potassium feldspar. The arsenic sandstone can be roughly divided into three types according to the degree of cover...
