Embodiment 1

[0032] figure 1 It is a schematic diagram of the overall structure of the soil device of the present application, such as figure 1 As shown, the soil device of the present application includes a device body 1, a slow-release fertilizer 2 and a covering layer 3, the top and inside of the device body 1 are hollow, and the slow-release fertilizer 2 is accommodated in the device body 1; the covering layer 3 is a porous structure, covering The layer 3 covers the device body 1 and is fixedly connected with the device body 1 .

[0033] The soil device of the present application, on the one hand, the covering layer 3 is a porous structure, and the covering layer 3 is coated on the device body 1, so that the plant seeds can fall into the device body 1 along with natural conditions such as wind or rain, so that the grass seeds Grow through the pores in the cover layer 3, and the slow-release fertilizer 2 can make the growth state of the grass better, so as to achieve the purpose of qui...

Embodiment 2

[0044] The present application also proposes a method for repairing degraded grassland soil using a soil device, which is suitable for the above-mentioned soil device, including the following steps:

[0045] Step S1, assembling the soil device: putting the slow-release fertilizer 2 into the device body 1, covering the device body 1 with the covering layer 3, and fixedly connecting with the device body 1;

[0046] specifically, figure 2 It is the longitudinal section view of the overall structure of the soil device of the present application, such as figure 2 As shown, in step S1, there is a height difference between the slow-release fertilizer 2 and the top of the device body 1, preferably a height difference of 1 cm, and the covering layer 3 and the device body 1 are fixed with fiber ropes, and the covering layer 3 is fixed on the device body 1 .

[0047] The height difference between the slow-release fertilizer 2 and the top of the device body 1 can prevent the slow-rele...

Abstract

The invention discloses a soil device and a method for remediating degraded grassland soil by using the same, relates to the technical field of soil remediation, and solves the technical problems of severe degradation of existing grassland, high grassland degradation treatment costs and long restoration periods. The soil device comprises a device body, slow-release fertilizer and a covering layer,wherein the top and the interior of the device body is hollow and the slow-release fertilizer is accommodated in the device body; and the covering layer is of a porous structure, covers the upper side of the device body and is fixedly connected with the device body. The soil device and the method are mainly used for remediating the degraded grassland soil.

Description

technical field [0001] The present application relates to the technical field of soil restoration, in particular to a soil device and a method for repairing degraded grassland soil by using the soil device. Background technique [0002] At present, environmental problems are becoming more and more serious, among which grassland degradation is the main problem. Grassland degradation mainly refers to the retrograde succession process of grassland ecosystem structural imbalance, primary productivity decline, and ecological function decline due to factors such as climate change and human irrational economic activities. [0003] People's overloading and overgrazing of grassland, excessive reclamation, and improper pasture management far exceed the self-healing ability of the soil, destroying the relative balance of the material cycle of the grassland ecosystem, causing the reverse succession of the ecosystem, reducing plant species, and deteriorating grass quality. , form alopeci...
