Problems solved by technology

[0005] The invention provides an ion-type rare earth mine tailings land improvement agent and a method for vegetation reclamation, which solves the lack of research on tailings land improvement technology in the prior art, poor selection of reclamation plants, unclear improvement purposes, and many control points are not clear. Planting trees directly after soil improvement leads to a very unsatisfactory reclamation effect

Abstract

The invention discloses an ionic type rare earth ore tailing sandy ground improver. The ionic type rare earth ore tailing sandy ground improver consists of the following preparation raw materials in parts by weight: 20 to 30 parts of sphagnum moss, 20 to 30 parts of algae mud, 10 to 15 parts of organic calcium-based montmorillonite, 1 to 5 parts of coconut shell cellulose, 5 to 10 parts of ammonium polyphosphate, 5 to 10 parts of biochemical potassium yellow acid and 20 to 30 parts of organic fertilizer. In addition, the invention also provides a vegetation reclamation method of an ionic typerare earth ore tailing sandy ground. The sphagnum moss, the algae mud, the coconut shell cellulose, the organic calcium-based montmorillonite, the ammonium polyphosphate, the biochemical potassium yellow acid and the organic fertilizer serve as the improver, the vegetation reclamation aim is fulfilled by planting Chinese pennisetum and melinis minutiflora, the problems that the ionic type rare earth ore tailing sandy ground soil has low water-retaining and fertilizer-retaining abilities and low organic matter content are effectively solved, and the problem that rare earth metal and heavy metalin the soil exceed the standard is solved; and after vegetation reclamation, the improvement effect of the ionic type rare earth ore tailing sandy ground is durable and the water-retaining and fertilizer-retaining abilities of the soil are high.

Description

technical field [0001] The invention belongs to the technical field of treatment and restoration of rare earth mine tailings, and in particular relates to an ion-type rare earth tailings land improver and a vegetation reclamation method. Background technique [0002] Ionic rare earth mines are important strategic resources in my country, mainly distributed in Jiangxi, Guangdong, Fujian, Hunan and Guangxi in the south. Among them, Ganzhou City, Jiangxi Province was mined the earliest and had the largest amount of mining, and has also made a great contribution to the local economic development. . However, for a long time, the mining of ion-type rare earth ores, especially the early mining, has mostly adopted the heap leaching process, that is, the ore rich in rare earths is transported from the weathered and semi-weathered layers under the topsoil to the heap leaching site, and is repeatedly leached with ammonium sulfate to obtain At the same time as the rare earth mother liqu...
