Abstract
The invention discloses a rapid ageratina adenophora cutting propagation technique for ecological restoration of mining areas. The technique comprises the main steps: laying humus soil in seedling raising trays, wherein the humus soil is prepared from substrate vermiculite, plant ash, carbon dust and mountain clay which are in the volume ratio of 1: 1: 2: 6, and the thickness of the laid humus soil is 4cm; preparing shoots from middle-part stems of 1-to-2-year-old ageratina adenophora plants with lateral buds in a manner that each cutting shoot reserves one stem node, the upper part of each stem node is reserved by 1-2cm, the lower part of each stem node is reserved by 3-5cm, surplus leaves are sheared until the leaves and the buds are in one-to-one correspondence, and meanwhile, each reserved leaf is sheared by 1/3 to 1/2; implanting the cutting shoots in the seedling raising trays in accordance with the cuttage depth that each stem node is exposed to the surface layer of the corresponding humus soil by 0.5-1cm; and after carrying out cuttage, putting the seedling raising trays in a pool filled with pure water, and carrying out culturing for one month. The technique has the beneficial effects that the technique is simple in process and is free of seasonal restrictions, and the obtained ageratina adenophora young seedlings are high in rooting rate.
Description
Technical field
The present invention relates to the rapid cuttage propagation technique of a kind of Eupatorium adenophorum in ecology of mining areas is repaired.
Background technology
At present, the restorative procedure of heavy-metal contaminated soil mainly contains physics, chemistry and biology reparation.Phytoremediation technology is the one in bioremediation technology, the advantage of this kind of recovery technique is that cost is low, effective, non-secondary pollution, application prospect are extensive, and after reclaiming, have more ecological benefits and aesthetic value, can reach the reparation of contaminated soil permanent cleanliness, thus be acknowledged as the green recovery technique of environmentally friendly original position.This technology utilizes that the enrichment of self-sow or super enriching plant absorb, transhipment and Enriching soil heavy metal be to plant shoot, then the process of burning and reclaiming heavy metal is gathered in the crops, its effect depends on how to improve aboveground vegetation part biomass and content of beary metal thereof, namely needs the more fast growth of seed selection, biomass large and the plant of energy enrichment or super one or more heavy metals of enrichment.
It is fast that Eupatorium adenophorum has spread speed, and ability of occupying is strong, is extensively distributed in the ground such as Yunnan Province of China, Guizhou, Sichuan, Guangxi, Tibet, Taiwan.There are some researches show that the enrichment that Eupatorium adenophorum is as stronger in Cd and Cr has to the heavy metal that mining area is different has certain Cd and Cr pollution amelioration potentiality.If the Eupatorium adenophorum root in Lan-Ni-Gou Gold Mine district, Guizhou, stem, leaf are 3.286,9.532 and 8.191 to the concentration coefficient of Cr respectively, transhipment coefficient is 2.7, much larger than 1; Be respectively 2.95,1.66 and 3.73 to the concentration coefficient of Cd, transhipment coefficient 0.91, close to 1; Also absorption is in various degree had to other heavy metal elements.Therefore, numerous researcher thinks that Eupatorium adenophorum can as a kind of pionner of ecology of mining areas Reparation and Reconstruction to do further research.
Chinese patent 201210282994.1 discloses a kind of Eupatorium adenophorum and is repairing the application in heavy metals mining area zinc lead bronze contaminated soil, this is applied as plants in the heavy metal pollution mining soil having this plant extensively to distribute by Eupatorium adenophorum, utilize its plant heavy metal zinc, lead and measuring copper characteristic absorption accumulation heavy metal, and its major part is transported to above-ground plant parts; Before its seed maturity, gather in above-ground plant parts, prevent its seed from flying away with the wind and spread outside mine, and aboveground vegetation part is carried out ashing process, extract heavy metal, to reach the object of repairing mining soil heavy metal zinc, lead and Cu-W ore deposit.Although the method is simple to operate and Financial cost is lower, the lower meeting of efficiency directly absorbing moisture due to its stem from soil causes its cuttage survival rate lower, has a strong impact on the effect of restoration of the ecosystem.
Summary of the invention
The problem to be solved in the present invention is to provide the rapid cuttage propagation technique of a kind of Eupatorium adenophorum in ecology of mining areas is repaired, and adopt this technical matters simply, to be not subject to seasonal restrictions, and the Eupatorium adenophorum seedling rooting rate obtained is high.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: the rapid cuttage propagation technique of a kind of Eupatorium adenophorum in ecology of mining areas is repaired, is characterized in that, comprise the following steps:
(1) in seedling-cultivating tray, lay humus soil, the volume ratio of humus soil configuration is matrix vermiculite, ash, carbon dust, mud=1, mountain: 1: 2: 6, and laying depth is 4cm;
(2) in the middle part of the Eupatorium adenophorum plant choosing 1-2 green tape lateral bud, stem section carries out fringe processed, wherein the length of lateral bud will be 1-3 centimetre, every root cuttage fringe retains a stipes, length is that stipes top retains 1-2 centimetre, stipes bottom retains 3-5 centimetre, cuts off unnecessary blade, retains leaf one bud, the blade of reservation is cut off 1/1 to two/3rd, cut sth. askew in 45 degree, the one end of inserting under cuttage fringe simultaneously;
(3) cuttage fringe is implanted in seedling-cultivating tray, and the cuttage degree of depth is that stipes spills humus soil top layer 0.5-1cm;
(4) after cuttage, seedling-cultivating tray is put into the pond of filling pure water to cultivate one month, the period that in incubation, during 10 times of every morning ~ afternoon 4, sunlight is stronger draws sunshade net above pond.
Technique effect of the present invention is mainly reflected in: Eupatorium adenophorum seedling percent is high, and the cycle is short, and output is large, and less energy consumption, is easy to pilot scale culture, is conducive to implant mass in ecology of mining areas is repaired.
Embodiment
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with embodiment, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Embodiment
1, be that 1: 1: 2: 6 Homogeneous phase mixing are configured to humus soil by vermiculite, ash, carbon dust, mountain mud according to volume ratio, the humus soil good permeability made like this, and also nutritious, be beneficial to cuttage fringe and grow fast; Then be laid in seedling-cultivating tray by humus soil, laying depth is 4cm, and will ensure that humic soil layer is compacted.Wherein the specification of seedling-cultivating tray is 660mm (length) × 340mm (wide) × 50mm (height), and hole count is 128 holes.
2, in the middle part of the Eupatorium adenophorum plant choosing 1-2 green tape lateral bud, stem section carries out fringe processed, and wherein in order to ensure the vitality of cuttage fringe, the length choosing the lateral bud of Eupatorium adenophorum plant will ensure 1-3 centimetre; During fringe processed, every root cuttage fringe retains a stipes, and skewer cutting length is that stipes top will retain 1-2 centimetre, and stipes bottom retains 3-5 centimetre, and experiment proves, the survival rate of the cuttage fringe in this length range is the highest; In order to avoid the excessive dehydration of cuttings, cut off unnecessary blade, retain leaf one bud, the blade of reservation is cut off 1/1 to two/3rd simultaneously.Cutting sth. askew in 45 degree, the one end of inserting under cuttage fringe, ensure that cuttage fringe can be inserted in seedling-cultivating tray fast smoothly.
3, cuttage fringe is implanted in seedling-cultivating tray, and the cuttage degree of depth is that stipes spills humus soil top layer 0.5-1cm;
