Ecological treatment system and ecological treatment method for gravel yard

Abstract

Disclosed are an ecological treatment system and an ecological treatment method for a gravel yard. The ecological treatment system comprises a soil treatment module and a planting restoration module.The soil treatment module comprises a crushing cavity, an improved matrix cavity and a mixing cavity. The planting restoration module comprises an irrigating and seeding device, a soil turning and impurity removing device and a plurality of planting troughs. The irrigating and seeding device comprises a rotating cavity, and the rotating cavity is divided into a seed storage cavity and an irrigation cavity by a partition plate. A plurality of rows of sowing devices are arranged on the outer side the seed storage cavity, and a plurality of rows of spraying heads are arranged on the outer side ofthe irrigation cavity. The soil turning and impurity removing device disposed below the irrigating and seeding device comprises a long rotating shaft and a plurality of rows of hook teeth disposed onthe long rotating shaft. Through holes are uniformly formed in the periphery of each planting trough, and gravel soil improved by the soil treatment module is paved in the troughs. The method combining physical improvement with biological improvement is adopted to fundamentally solve the problems of excessive gravel, hardening, poor water storage capacity and low nutrition of the soil of the gravel yard, and accordingly, the original ecosystem of the gravel yard is restored.

Description

technical field [0001] The invention relates to the technical field of sand and gravel quarry restoration, and more specifically, relates to a sand and gravel quarry ecological management system and method. Background technique [0002] As a kind of abandoned land, the sand and gravel yard not only occupies a large amount of land, but also destroys a large area of ​​vegetation and the original ecosystem, forming extreme habitat conditions, resulting in the disappearance of a large number of species, a sharp decline in biodiversity, and the ecosystem However, there are more sand and gravel in the sand and gravel quarry, which can easily cause the soil to compact and cause difficulties for secondary development and utilization. Therefore, the ecological restoration of sand and gravel quarries has become one of the current research hotspots. [0003] In the ecological restoration of sand and gravel quarries, soil matrix improvement is the first and core problem that needs to b...
