Problems solved by technology

However, due to the transitional needs of economic and social development, human beings represented by land reclamation, reclamation and overgrazing have led to the deterioration of the ecological environment of the Songnen Grassland. The problems of "degeneration, salinization and desertification" of the grassland are particularly serious, and the carbon sequestration capaci

Example Embodiment

[0026] Example 1

[0027] Provides a method of rapidly enhanced severe degraded sheep meadow vegetation carbon production, steps below:

[0028] Step 1: The degree of vegetation degradation of the meadow meadow is evaluated as the evaluation index of vegetation degradation (mild, moderate and severe), and the vegetation coverage rate is ≥70% for mild degradation, 70%. > Vegetation coverage is ≥ 40% is moderate degradation, and the vegetation coverage is <40% is severe degradation, and the evaluation time is generally the end of July or in early August (the highest random period of vegetation).

[0029] Step 2: The whole place, light flipping, shallow vertical depth is 6 ~ 10cm, the light is broken, and the implementation time is April.

[0030] Step 3: Application of the ecosystem, the ecological preparation is mainly weathering coal, the humic acid content of weathered coal is ≥30%, the particle size is ≤ 3mm, the application time is in advance or in the middle of the year, and t...

Abstract

The invention relates to a method for increasing the carbon sequestration amount of severely-degraded leymus chinensis meadow vegetation. The method comprises the steps that 1, soil preparation is conducted on the position, without leymus chinensis dominant species coverage or with low plant coverage rate, in a preset area in shallow ploughing and light raking manner, the soil preparation time isthe first ten days of April in the same year, soil blocks need to be smashed in the soil preparation process, and the soil turning depth needs to be 6-10 cm; 2, a predetermined ecological preparationis applied to the prepared land in the first ten days or the middle ten days of April of the same year; 3, a predetermined fertilizer is applied to the land to which the predetermined ecological preparation is applied in the first ten days or the middle ten days of April in the same year; 4, predetermined grass seeds are sowed in the middle ten days or the last ten days of April in the same year on the land to which the predetermined fertilizer is applied; and 5, later-period management and protection are conducted, wherein watering is mainly conducted in the sowing period. The method can effectively improve the growth environment of the vegetation, improve the productivity and carbon sequestration capacity of the vegetation and increase the carbon sequestration amount of the vegetation.

Description

technical field [0001] The invention relates to a method for increasing the carbon sequestration capacity of heavily degraded Leymus chinensis meadow vegetation, and belongs to the technical field of grassland carbon sink emission reduction. Background technique [0002] Carbon is the most basic cyclic substance in the ecosystem, mostly in the form of CO 2 The forms of spheres migrate and transform between the biosphere, hydrosphere, lithosphere and atmosphere, and remain in a relatively balanced state. However, due to human activities dominated by agricultural reclamation, overgrazing, and burning of fossil fuels, atmospheric CO 2 The sharp increase in the content of carbon dioxide destroys the balance of the global carbon cycle, increases carbon sources while reducing carbon sinks, and changes the global climate. In the context of global warming, increasing terrestrial response to CO 2 The fixation of carbon emissions, the reduction of carbon emissions, and the fight fo...
