Abstract
The invention discloses a method for promoting growth of toricellia angulata var. intermedia in a lead zinc ore degraded area. The method comprises the following steps of: harvesting miscanthus floridulus, ferns and dwarf shrubs, drying, piling, covering soil on wood piles, exposing the lower parts of the wood piles, igniting the wood piles from the lower part, slowly burning the wood piles, collecting fired soil, turf and grass ash after the fire is extinguished, and mixing to prepare a soil impurity fertilizer; preparing a mixed modifier from 10 weight percent of moss granules, 20 weight percent of green coriaria sinica maxim manure and 70 weight percent of soil impurity fertilizer; selecting and establishing a sample land in the lead zinc ore degraded area, flattening, making planting ditches, and planting toricellia angulata var. intermedia cuttings in the planting ditches; and applying 15kg of mixed modifier to each planting ditch, covering the soil, and covering pad-like moss sheets on the soil. By adopting the technology, establishment and growth of the toricellia angulata var. intermedia can be promoted, the toricellia angulata var. intermedia is continuously clumped and expanded to the close place, and vegetation with dominant toricellia angulata var. intermedia is rebuilt. The method is simple and feasible, and avoids ecological risks; and materials are convenient to take.
Description
Technical field
The present invention relates to the ecological recovery field, particularly relate to a kind of promotion torricellia angulata
( Toricellia angulataVar. intermedia
)Method in plumbous zinc ore degenerate region growth.
Background technology
Area, the mine ecosystem is degenerated, and vegetation lacks, severe water and soil erosion, and the heavy metal diffusion causes regional pollution, surrounding area human health to be on the hazard and endangers.The mine degraded ecosystem is carried out construction and the sustainable development that ecological recovery helps harmonious society.
The top priority of area, mine ecological recovery is to recover and revegetation.Mine degraded ecosystem environmental condition is abominable: the topsoil disappearance; Soil depletion, content of beary metal is high; The matrix retention ability is weak, moisture lacks; Matrix acidifying is serious.Under this harsh environmental conditions, most plants are difficult to nature and settle down growth.Add allogene and can improve mine degeneration matrix, be built with the soil system that benefits plant growing, promote plant growing and revegetation.
Summary of the invention
The present invention provide a kind of employing liver moss, Coriaria sinica (
Coriaria nepalensis) young stem and leaf and farmyard manure preparation mixing modifying agent, this mixing modifying agent is nutritious, and water binding capacity is good, can promote torricellia angulata wood
( Toricellia angulataVar. intermedia
)Grow in plumbous zinc ore district; After tooth sheath handle wood is successfully settled down growth a period of time, tap its young stem and leaf, landfill promotes torricellia angulata constantly to the vicinity expansion of growing thickly, the dominant vegetation of Fast Reconstruction torricellia angulata with this in adjacent soil.
Technical scheme of the present invention
A kind of method that promotes torricellia angulata in plumbous zinc ore degenerate region growth may further comprise the steps:
(1) collects liver moss, cut and process the liver moss particle;
(2) collect cushion liver moss sheet;
(3) collect the Coriaria sinica young stem and leaf, process Coriaria sinica green manure;
(4) harvesting Caulis Miscanthis floriduli (
Miscanthus floridulus), pteridophyte and undershrub, dry, build up rick, cover on the rick
Lid earth, the rick bottom is exposed, lights rick from the bottom, smoulder, fire extinguishes the back and collects baked wheaten cake soil, the peat composed of rotten mosses and plant ash, mixes and processes farmyard manure;
(5) liver moss particle, Coriaria sinica green manure and farmyard manure are mixed with the mixing modifying agent by weight proportion: liver moss particle 10%, horse
Sang Lvfei 20%, farmyard manure 70%;
(6) harvesting torricellia angulata stem is cut and is cut into slotting fringe;
(7) build appearance ground in the choosing of plumbous zinc ore degenerate region, make the plantation ditch after smooth, insert in the plantation ditch and plant torricellia angulata and insert fringe; Execute in every plantation ditch to fill out and mix modifying agent 15kg, mulching soil covers cushion liver moss sheet on the soil;
(8) after torricellia angulata is inserted the work of fringe one-tenth, a large amount of stems of growing thickly, tap the tender stem and the blade of torricellia angulata; Dig the soil between the loose adjacent plantation ditch, the young stem and leaf landfill of tapping in soil, is improved the soil, promote torricellia angulata constantly to the vicinity stretching, extension of growing thickly with this.
Principle is:Through cementation, liver moss and soil particle connect, are gathered into the coherent and intensive moss crust that is covered in the face of land, so liver moss has the effect of good maintenance soil and storage or saving moisture, can prevent erosion.Liver moss can be adsorbed fixedly, and heavy metal stays soil nutrient with holding.Liver moss can accumulate moisture and the floating dust in the surrounding environment, and the secretion organic matter promotes rock to decompose, and forms soil.
The rotten decomposition of liver moss can be increase soil fertility.The browse of Coriaria sinica can be used as green manure, increases the soil organic matter.The torricellia angulata cuttage is prone to into alive, is the shape of growing thickly after the felling, and leaf is membranous, very large, and stem growth is commonly usedly improved the soil as green manure rapidly and matter is soft.Lead, zinc and the cadmium of the accumulation of torricellia angulata root are many, and average content respectively is 603.2,116.5 and 18.6 mg.kg
-1, the average content of the lead of its acrial part, zinc and cadmium respectively is 3.1,1.6 and 0.2mg.kg
-1
Plant ash in the farmyard manure contain and enrich mineral element.The peat composed of rotten mosses in the farmyard manure is adsorbable to stay moisture and nutrient with holding, enhancement of plant drought resistance and minimizing nutrient loss; The peat composed of rotten mosses and plant ash are alkalescence, can weaken soil acidification.
Mixing modifying agent with liver moss, Coriaria sinica green manure and farmyard manure preparation is nutritious, water binding capacity good, can promote the ground growth of torricellia angulata degeneration in the mine.Tap the torricellia angulata young stem and leaf and make green manure, sustainablely improve the soil and promote torricellia angulata to the vicinity expansion of growing thickly.
Beneficial effect of the present invention
(1) liver moss can accumulate moisture and the floating dust in the surrounding environment, and the secretion organic matter promotes rock to decompose, and forms soil.
(2) liver moss has the effect of good maintenance soil and storage or saving moisture, can prevent erosion.
(3) the liver moss decomposition of rotting can be increase soil fertility, and liver moss can be adsorbed fixedly heavy metal and hold and stay soil nutrient, helps
Plant growing.
(4) make green manure with the browse of Coriaria sinica, can increase the soil organic matter.
(5) farmyard manure contains the peat composed of rotten mosses and plant ash; The plant ash mineral element is abundant, and the peat composed of rotten mosses is adsorbable to stay moisture and nutrient with holding, and strengthens
Plant drought resistance and minimizing nutrient loss; The peat composed of rotten mosses and plant ash are alkalescence, can weaken soil acidification.
(6) the torricellia angulata cuttage is prone to into alively, and growth rapidly is the shape of growing thickly after the felling, and leaf is very large, stem matter is soft, and the perishable decomposition of cauline leaf can be improved the soil as green manure.
(7) torricellia angulata root ability enriched lead, zinc and cadmium can be fixed these heavy metals migrations of resistance control.
(8) adopt present technique can promote torricellia angulata to settle down growth, and constantly to vicinity expansions of growing thickly, the dominant vegetation of reconstruction torricellia angulata.
(9) present technique is drawn materials conveniently, and is simple, no ecological risk.
