Abstract
The invention discloses a revegetation method for a biomass landfill. The revegetation method includes that planting soil mixed with organic fertilizer and turfy soil is added into a soil layer for planting pioneer plants to change secondary bare land with brushwood and bosk into forests; soil property of biomass-covered soil is improved by utilizing planting soil to guarantee planted plants not prone to death caused by the influence of gas, liquid and energy generated from biomass degradation; and meanwhile revegetation work amount and investment are reduced and soil utilization rate is increased, and harmful environmental effect from soil bareness is reduced.
Description
Technical field
The invention belongs to the greening technique field, be specifically related to a kind of living beings landfill yard method for recovering vegetation.
Background technology
Along with industrial expansion, the growth of population, original vegetation sharply reduces, and the environment that the mankind depend on for existence goes from bad to worse.Large tracts of land serious water shortage, arid cause desertification of land; Urban Scale, but the farming area reducing caused.The living beings landfill not only can reduce carbon dioxide content in atmosphere, and after the living beings Closure of landfill site, in warmer climate, area with heavy rainfall, by manpower intervention, can recover rapidly to form new vegetation ecological system; In the area dry, that rainfall is few, organic mass-energy of rotting in the living beings landfill yard is improved soil structure, gas permeability and the moisture capacity of soil are improved, by the human assistance revegetation, can form good ecological recovery system, to resisting desertification of land, promote the oasis to form and have great importance.But produce a large amount of biological degradation gas, liquid and heat after the living beings landfill, plant growth is had a great impact, revegetation needs a process, also there is no at present the method for a kind of living beings landfill yard revegetation both at home and abroad.
Summary of the invention
The present invention is intended to overcome the deficiencies in the prior art, a kind of living beings landfill yard method for recovering vegetation is provided, to guarantee that the plant of being planted is not subject to biomass degradation gas, liquid and heat effects and death, reduce simultaneously vegetation recovery engineering amount and investment, improve the Soil Utilization rate, reduce soil bareness to the harmful effect of environment.
In order to achieve the above object, technical scheme provided by the invention is:
Described living beings landfill yard method for recovering vegetation is the thick planting soil of soil upper berth one deck 2～100cm that covers at the living beings landfill yard, then plants herbaceous plant, shrub plant and magaphanerophytes; Described planting soil is to be mixed by 3～5:1～2:1 by normal soil, turfy soil and the organic matter that becomes thoroughly decomposed to form.The organic matter that wherein becomes thoroughly decomposed is commercially available or self-control.
Concrete described method comprises the steps:
(1) pulverize after the soil removal sandstone with the landfill yard periphery, cross 1～3 order mesh screen, then burn together with plant leaf, weeds, crop stalk, form turfy soil after smoke fire is roasting; Soil, the turfy soil of landfill yard periphery and the organic matter that becomes thoroughly decomposed are mixed into planting soil by 3～5:1～2:1;
(2) after the living beings landfill, the thick planting soil of soil upper berth one deck 2～100cm that the living beings landfill yard covers, sowing herbaceous plant during benign climate;
(3) press the kind plant hole of seeding row spacing (2～3) m * (2～3) m excavation (20～30) cm * (20～30) cm * (20～30) cm, in fill out the planting soil of 10～20cm, the shrub plant of planting on this planting soil; Press the kind plant hole of seeding row spacing (5～10) m * (5～10) m excavation (50～80) cm * (50～80) cm * (50～80) cm, in fill out the planting soil of 20～40cm, the magaphanerophytes of planting on this planting soil.
Wherein, described herbaceous plant is selected from one or more in green foxtail, field bindweed, lady's-grass, india lovegrass, eleusine indica, Herba Eragrostidis ferrugineae, clover or clover; Described shrub plant is selected from one or more in shrub lespedeza, shrubby flase indigo or prunus cerasifera; Described magaphanerophytes is selected from one or more in arbor-vitae, Chinese juniper, torch tree, acer monoes, Luan Shu, elm, paper mulberry, China tree, locust tree, ash tree, glossy privet, Amur honeysuckle, tree-of-heaven, Chinese ilex or cdear.
The invention will be further described below in conjunction with principle:
A kind of living beings landfill yard method for recovering vegetation of the present invention is to plant pionner after burying soil layer and add the planting soil of the mixing such as fertilizer, turfy soil again, and secondary barren is developed to the woods by thick grass, shrub.
The normal soil of landfill yard periphery is pulverized after removing sandstone, crosses 1～3 order mesh screen, then burns together with plant leaf, weeds, crop stalk, and soil structure improves after smoke fire is roasting, fertility improves, and forms turfy soil.The normal soil of landfill yard periphery, turfy soil and the organic matter that becomes thoroughly decomposed mix by 3～5:1～2:1 and just form planting soil.
After the living beings Closure of landfill site, the living beings surfaces is repaired, form top, slope and domatic, then cover the soil of 30～150cm.Adopt normal tree-planting method on the top, slope during revegetation, domatic employing " fish scale pit " form is also equidistantly excavated planting hole along contour, in order to hold back natural precipitation and irrigation water, prevents erosion.
Press seeding row spacing (1～5) * (1～5) m and excavate (30～100) * (30～100) cm, the plant hole of dark 20～120cm is imbedded the planting soil of thickness 10～50cm in planting hole.
Select to grow in the barren adverse circumstances of adapted soil, have resistance, drought resisting, cold-resistant, anti-barren, disease and insect resistance; Growth, fertility is strong, preferably can have nitrogen fixing capacity, improves the Nitrogen In Soils constituent content; Well developed root system, the rudiment ability is strong, and consolidated soil, prevent erosion effectively; Sow, plant easily, the pionner that survival rate is high and adaptive plant.Selected herbaceous plant requires to have the ability of surviving the winter, to save cost.
At first choose the herbaceous plant of impoverishment tolerant, fast-growing with improvement soil, recover soil fertility.Herb Root is flourishing, soil is had some improvement, and can create conditions for the growth of tree and shrubs class other plant.Some plants very strong to the landfill yard adaptive capacity to environment can be planted in the subtropical zone, such as cypress, Chinese tallow tree, yucca, sweet-scented oleander, the rose of Sharon etc., accelerate improvement soil, and dam rainwater and reduce and ooze drop liquid, improve the subenvironment in group of the absorption by plant and transpiration, be that better condition is created in the other plant growth.Qiao fills with careless combination, is built with the ecosystem of level.
Subtropical zone living beings landfill yard revegetation, adopt tall, fill with collocation, the mode that thick forest is planted is selected anti-barren, anti-harmful gas, seeds that material is tough and tensile, preferent sees Table 1.
Table 1, subtropical zone living beings landfill yard revegetation preferent
According to the time after the living beings Closure of landfill site, grave mound thickness, take full advantage of the Greening functions of pionner, and suitably plant the strong draft of other patience, shrub, arbor etc., increase the diversity of plant community, build relatively stable and a ecosystem that can self, the community collocation of plant sees Table 2.
The plant of plantation in table 2, suitable subtropical zone living beings landfill yard
Compared with prior art, the beneficial effect of the inventive method is:
The inventive method is planted pionner again after burying soil layer and add the planting soil of the mixing such as fertilizer, turfy soil, secondary barren is developed to the woods by thick grass, shrub.Utilize planting soil improvement living beings overburden soil soil property, to guarantee that the plant of being planted is not subject to biomass degradation gas, liquid and heat effects and death, reduce simultaneously vegetation recovery engineering amount and investment, improve the Soil Utilization rate, reduce soil bareness to the harmful effect of environment.
