Problems solved by technology

In order to restore the ecology of grasslands, traditional animal husbandry practitioners have explored a set of methods to loosen the soil, but they are not suitable for the restoration of large-scale grasslands due to low efficiency and high cost
In addition, the closed method is adopted for recuperation, but according to this method, it is closed for a long time and pastures are planted year by year. The time is more than 10 years and the recovery effect is not ideal. degenerate again

Embodiment 1～5

[0025] A soil function restoration method for degraded hardened grasslands, comprising the following steps:

[0026] (1) Sealing: enclosing and prohibiting grazing of the degraded grassland area, and the boundary of the enclosure is set at the border between the degraded grassland and the non-degraded grassland;

[0027] (2) Debonding: Between the rain in a year and the solar term of Lixia, use a grassland debonding machine to perform rolling loosening on the compaction characteristic area of ​​the degraded grassland. The grassland debonding machine has a blade loosening mechanism and a needle-punching loose Mechanism, the loosening method is rough broken by the blade-type loosening mechanism, and then loosened by the acupuncture-type loosening mechanism;

[0028] (3) Activation: Prepare the soil activator according to the formula components. According to the size of the degraded grassland area, select a number of agricultural model aircraft spraying aircraft for spraying oper...

Abstract

The invention discloses a soil function restoration method for a degenerated hardened grassland. The method comprises the steps of banning, wherein enclosing and banning grazing are carried out on a degenerated grassland area; hardened soil loosening, wherein a grassland hardened soil loosening machine is utilized to loosen a hardened characteristic area of the degenerated grassland; activating, wherein a soil activator is used for spraying and activating the degenerated grassland; seeding, wherein seeds of drought-enduring plants and pastures are sown; reseeding, wherein drought-enduring plants and pastures are reseeded depending on the circumstances; and rehabilitation, wherein timely grazing stimulates rehabilitation of plants after growth. The soil function restoration method for the degenerated hardened grassland has the advantages that physicochemical, chemical and biological means are combined, so that the soil function restoration is completed gradually and sustainably, the method has very high practical value and contributes to the management of the degenerated hardened grassland in China.

Description

technical field [0001] The invention relates to the technical field of ecological restoration, in particular to a soil function restoration method for degraded hardened grassland. Background technique [0002] With the development of human society, ecological deterioration is becoming more and more serious, threatening the foundation of the survival of the vast biosphere including human beings. Grassland degradation and hardening are one of the manifestations of ecological deterioration. my country is no exception, especially in Inner Mongolia, Xinjiang, and Northeast China. Grassland degradation and compaction caused by overgrazing has become more serious and difficult to manage. The trend is not optimistic. The arid and semi-arid climate has caused the fragility of the grassland vegetation ecosystem. In order to restore the ecology of grasslands, traditional animal husbandry practitioners have explored a set of methods to loosen the soil, but they are not suitable for the...
