specific Embodiment approach 1

[0022] Specific implementation mode one: the method for improving forest carbon sink capacity of the present embodiment is carried out according to the following steps:

[0023] Select robust white birch saplings and larch saplings, and plant them in the form of coniferous and broad-leaved mixed forests in the artificial forest planting area to realize the above-mentioned improvement of forest carbon sink capacity; the specific planting method is: select a gentle slope planting area, and the slope angle of the gentle slope is ≤10°, 10~20° and ≥20°; and plant Miscanthus or Pennisetum at the bottom of the slope;

[0024] Among them, on the sunny slopes with a slope angle of ≥20°, and the annual average sunshine time is higher than the average value of the sunny slopes, the planting area of ​​larch saplings is ≥80%; The planting area ratio of saplings is 1:1~2; on sunny slopes with a slope angle of ≤10°, birch saplings are mainly planted, and multiple birch saplings and a larch s...

specific Embodiment approach 2

[0030] Specific embodiment two: the difference between this embodiment and specific embodiment one is: the preparation method of the composite water retaining agent in this embodiment is implemented according to the following steps:

[0031] 1. Soak the biochar in the compound bacteria solution to obtain the biochar containing bacteria;

[0032] 2. Take out the corn cob by mechanical method, crush the corn cob into a block, mix the inorganic fertilizer, ethylene glycol and water to obtain a mixed fertilizer, then soak the crushed corn cob in the mixed fertilizer to obtain the corn cob containing fertilizer ;

[0033] 3. Mix the biochar containing bacteria and the corncob containing fertilizer evenly to obtain a biomass-biochar mixture;

[0034] 4. Mix the biomass-biochar mixture, kaolin and traditional Chinese medicine materials evenly to obtain a composite water retaining agent;

[0035] Wherein the composite bacterial liquid described in step 1 contains Streptomyces grisea...

specific Embodiment approach 3

[0036] Specific embodiment three: the difference between this embodiment and specific embodiment one is: the preparation process of biochar described in step one is as follows:

[0037] Put the biomass into a tube furnace, conduct high-temperature treatment at a temperature of 350-500°C for 1.5-2.5 hours under anaerobic conditions, add water and oxidize it at a temperature of 400-600°C, and then heat it at 600-700°C After reduction at a temperature of ℃, biochar is obtained.

[0038] The biochar prepared by this embodiment has a pore structure (pore diameter 3-10 μ m, specific surface area up to 100-230 m 2 / g), and there are a large number of charged groups on the inner surface of the pores, such as phenolic hydroxyl groups, alcoholic hydroxyl groups, and carboxyl groups, which can reduce metal elements in soil through physical adsorption of hierarchical pores and electrostatic adsorption of charged groups. The movement of trees prevents the absorption of heavy metals by tre...

Abstract

The invention discloses a method for improving forest carbon sequestration capacity, and relates to the field of forestry. The invention aims to solve the problem that the carbon sequestration capacity of an existing artificial forest needs to be improved, and provides the method for improving the forest carbon sequestration capacity. According to the method, white birch and larch are adopted as tree species for carbon sequestration, planting is conducted in a conifer-broadleaf mixed forest manner, and therefore the carbon sequestration capacity is improved; meanwhile, the planting manner is adjusted according to different slopes of planting areas, so that the white birch with the high carbon sequestration capacity and the larch with the weak carbon sequestration capacity are reasonably distributed to the areas suitable for growth of the white birch and the larch; and a composite water-retaining agent is added to improve the growth state of the white birch and the larch, so that the carbon sequestration capacity is improved. The method is applied to the forestry field.

Description

technical field [0001] The invention relates to the field of forestry, in particular to a method for increasing forest carbon sinks. Background technique [0002] Forests have the advantages of biomass, huge productivity, and high carbon content. They are the main carbon storage pool of the terrestrial biosphere and play an important role in the global carbon cycle and the response to climate change. The coniferous and broad-leaved mixed forest in the Xiaoxing’an Mountains is the main zonal forest vegetation in my country and a typical temperate coniferous and broad-leaved mixed forest. It has the characteristics of unique construction species, rich species diversity, and complex spatial structure. As much as 1 / 3 of the area. Therefore, it is extremely important to increase the carbon storage of forests, especially plantations. [0003] Larix (Larix) is an important timber and ecological tree species in the Northeast, Northwest, North China and the northern subtropical alpi...
