Description
Technical field
The present invention relates to a kind of rapid cuttage propagation method of Eupatorium adenophorum in ecology of mining areas reparation.
Background technology
At present, the restorative procedure of heavy-metal contaminated soil mainly has physics, chemistry and biology reparation.Phytoremediation technology
It is one kind in bioremediation technology, the advantages of such a recovery technique is that cost is low, effect is good, non-secondary pollution, application prospect
Extensively, and after reclaiming more ecological benefits and aesthetic value are had, can reach to contaminated soil permanent cleanliness reparation, thus quilt
It is known as environmentally friendly green recovery technique in situ.The technology is absorbed using the enrichment or super enriching plant of nature growth, turned
Then fortune and Enriching soil heavy metal are harvested the process for burning recycling heavy metal, its effect depends on to plant shoot
Aboveground vegetation part biomass and its content of beary metal are how improved, that is, needs that the more speeds of growth of selection and breeding are fast, biomass is big
And it can be enriched with or the plant of super enrichment one or more heavy metal.
Eupatorium adenophorum has spread speed fast, and it is strong to occupy ability, has been widely distributed in Yunnan Province of China, Guizhou, Sichuan, wide
The ground such as west, Tibet, Taiwan.Some researches show that Eupatorium adenophorum the heavy metal such as Cd and Cr different to mining area have stronger enrichment
Effect, has certain Cd and Cr pollution amelioration potentiality.If the Eupatorium adenophorum root, stem, leaf in Guizhou Lan-Ni-Gou Gold Mine area are to Cr
Concentration coefficient is 3.286,9.532 and 8.191 respectively, and transhipment coefficient is 2.7, much larger than 1；Concentration coefficient to Cd is respectively
2.95th, 1.66 and 3.73, coefficient 0.91 is transported, close to 1；Also there is different degrees of absorption to other heavy metal elements.Therefore,
Numerous researchers think that Eupatorium adenophorum can make further as ecology of mining areas reparation with a kind of pionner rebuild
Research.
Chinese patent 201210282994.1 discloses a kind of Eupatorium adenophorum repairing complex ore area heavy metal zinc lead bronze Polluted Soil
Application in earth, the application are in having there is the widely distributed heavy metal pollution mining soil of the plant by Eupatorium adenophorum plantation
In, heavy metal is accumulated using its plant pair heavy metal zinc, lead and measuring copper characteristic absorption, and its major part is transported to plant
Aerial part；Above-ground plant parts is gathered in before its seed maturity, prevents its seed drifts with the wind from being spread to outside mine, and will
Aboveground vegetation part carries out ashing processing, extracts heavy metal, to reach the mesh for repairing mining soil heavy metal zinc, lead and Cu-W ore deposit
's.Although this method is easy to operate and financial cost is relatively low, due to its stem absorbed directly from soil the efficiency of moisture compared with
It is low that its cuttage survival rate can be caused relatively low, seriously affect the effect of restoration of the ecosystem.
The content of the invention
The problem to be solved in the present invention is to provide a kind of rapid cuttage breeding side of Eupatorium adenophorum in ecology of mining areas reparation
Method, using this method technique it is simple, be not subject to seasonal restrictions, and obtained Eupatorium adenophorum seedling rooting rate is high.
In order to solve the above-mentioned technical problem, the technical solution adopted by the present invention is：A kind of Eupatorium adenophorum is repaiied in ecology of mining areas
Rapid cuttage propagation method in multiple, it is characterised in that comprise the following steps：
(1) fertile soil is laid with seedlings nursing plate, the volume ratio of fertile soil configuration is matrix vermiculite, plant ash, carbon dust, minishanny
=1: 1: 2: 6, laying depth 4cm；
(2) choose stem section in the middle part of the Eupatorium adenophorum plant of 1-2 green tape lateral buds and carry out fringe processed, the wherein length of lateral bud will be
1-3 centimetres, every cuttage fringe retains a stipes, and length retains 1-2 centimetres for stipes top, and stipes lower part retains 3-5 centimetres,
Unnecessary blade is cut off, retains one bud of a leaf, while the blade of reservation is cut off 1/3rd and arrives half, cuttage fringe underthrust
The beveling of 45 degree of one end；
(3) in cuttage fringe implantation seedlings nursing plate, cuttage depth leaks out fertile soil top layer 0.5-1cm for stipes；
(4) seedlings nursing plate is put into the pond for fill pure water after cuttage and cultivated one month, every morning in incubation
When 10~afternoon 4 when the sunlight stronger period sunshade net is drawn above pond.
The present invention's has the technical effect that：Eupatorium adenophorum seedling percent is high, and the cycle is short, and yield is big, less energy consumption,
It is easy to pilot scale culture, is conducive to the large-scale plantation in ecology of mining areas is repaired.
Embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, with reference to embodiments, to the present invention
It is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, it is not used to
Limit the present invention.
Embodiment
1st, vermiculite, plant ash, carbon dust, minishanny are uniformly mixedly configured into fertile soil according to volume ratio for 1: 1: 2: 6, so
Manufactured fertile soil good permeability, and it is full of nutrition, beneficial to cuttage fringe fast-growth；Then fertile soil is laid in seedlings nursing plate
It is interior, laying depth 4cm, and to ensure that humic soil layer is compacted.Wherein the specification of seedlings nursing plate is 660mm (length) × 340mm
(width) × 50mm (height), hole count are 128 holes.
2nd, choose stem section in the middle part of the Eupatorium adenophorum plant of 1-2 green tape lateral buds and carry out fringe processed, wherein in order to ensure cuttage fringe
Vitality, choosing the length of lateral bud of Eupatorium adenophorum plant will ensure there be 1-3 centimetres；During fringe processed, every cuttage fringe retains one
A stipes, and skewer cutting length will retain 1-2 centimetres for stipes top, and stipes lower part retains 3-5 centimetres, it is demonstrated experimentally that this
The survival rate highest of cuttage fringe in a length range；In order to avoid the excessive dehydration of cuttings, unnecessary blade is cut off, retains a leaf one
Bud, while the blade of reservation is cut off 1/3rd and arrives half.45 degree of one end beveling of cuttage fringe underthrust, ensure that cuttage
Fringe can be quickly successfully inserted in seedlings nursing plate.
3rd, in cuttage fringe implantation seedlings nursing plate, cuttage depth leaks out fertile soil top layer 0.5-1cm for stipes；
