Slag mountain vegetations and planting method thereof

Abstract

The invention relates to slag mountain vegetations and a planting method thereof, belongs to the technical field of ecological remediation for slag mountains, and mainly aims to solve the problem of ecological remediation for mining wasteland. The slag mountain vegetations comprise planting steps, arbors and bushes. The slag mountain vegetations are characterized by further comprising straw seedling raising containers, wherein the straw seedling raising containers comprise straw seeding raising rods and straw seedling raising earthen bowls; the arbors are subjected to intensification field planting in the straw seedling raising earthen bowls; the bushes are developed in root systems and bred by an intensification seedling raising technique with the straw seedling raising rods; the arbors and the bushes are integrally transplanted on a slag mountain together with the straw seedling raising containers, a planting platform in step-shaped distribution is artificially rebuilt on the slope body of the slag mountain, the width of the planting platform is not smaller than 1m, and large hard stones are tiled outside the planting platform and are tramped; and the bushes are transplanted on sloping surfaces, and the arbors are transplanted on flat ground. The planting method comprises the steps of performing field planting on the arbors through an intensification field planting techniquewith the straw seedling raising earthen bowls and the straw seedling raising rods, breeding the bushes, and performing integral transplanting to the trimmed slag mountain.

Description

technical field [0001] The invention belongs to the technical field of slag hill ecological restoration, and in particular relates to a slag hill vegetation and a planting method thereof. Background technique [0002] Abandoned mines are the earliest typical cases of ecological destruction that have attracted attention in the world. In these areas, there are a large number of gravel piles formed by stripped topsoil, mined rock fragments and low-grade ore fragments, as well as tailings and waste slag accumulations after the mined ore has been selected for concentrate. Collectively referred to as coal mines and non-coal slag hills. [0003] Coal mines and non-coal slag mountains are places where mining wastes are discharged intensively, including humic topsoil, weathered rock fragments, lean ore, etc., and have the following characteristics: [0004] 1. Poor permeability, rainwater leaching, erosion of slope, easy to landslide. [0005] Coal mines and non-coal slag hills ar...

Problems solved by technology

[0006] 2. Excavate the tree planting pit, the bottom of the pit is empty, the water leaks, and it is difficult to store

But at the same time, the above method also has many limitations: for example, the surface layer of foreign soil covers a large amount of engineering and high cost; foreign soil spraying is not suitable for northern arid areas, the maintenance cost is high, and it is difficult to form forests, and the flowers and plants will be seriously degraded in the later stage; Due to the lack of necessary measures to ensure the survival of plants, the soil has poor water storage and fertilizer retention capacity, it is difficult to store water, and the survival rate of seedlings in the later stage is extremely low, etc.
