Description
Technical field
The invention belongs to the reparation field of Heavy-Metal-Contaminated Environments, more particularly to the method for repairing orchard cadmium pollution soil.
Background technology
As the factors such as industrial pollution in recent years, field irrigation, material used for agriculture cause cadmium pollution problem to be on the rise.China
Cadmium pollution soil area up to 200,000 square kilometres, accounts for the 1/6 of total area under cultivation.It is used as a kind of emerging and environmentally friendly reparation side
Method, phytoremediation is gradually risen, and phytoremediation utilizes remote super common plant of the specified plant to specific heavy metal
Accumulation ability, by heavy metal, soil enrichment is in plant again, and most plant harvesting can depart from heavy metal from soil at last.
S. photeinocarpum (Solanum photeinocarpum) is annual plant of Solanaceae, high up to 1 meter, is a kind of common
Orchard weed, it is known that there is stronger accumulation ability to cadmium.
But regrettably, it is a kind of potential Cd-hyperaccumulator, because it is transported, coefficient is also distant from 1 (to be commented
The cadmium accumulation ability of the important indicator of valency super enriching plant, i.e. aerial part exceedes under ground portion, because generally harvesting is all only
Aerial part is gathered in, if also gathering under ground portion simultaneously, although most can fully remove cadmium, but because workload greatly increases
Plus, it is difficult to possess reality and repair meaning).
Moreover, under the conditions of high concentration cadmium pollution, S. photeinocarpum also further declines to the accumulation ability of cadmium.
Therefore how to improve S. photeinocarpum is that prior art thirsts for solution for a long time to orchard cadmium soil pollution repair ability
Certainly but open question.
The content of the invention
The purpose of present example is to provide the method that S. photeinocarpum repairs orchard cadmium pollution soil ability that improves, it is intended to
Further improve the ability that S. photeinocarpum repairs orchard cadmium pollution soil.
In order to realize foregoing invention purpose, the technical solution adopted by the present invention is as follows：
It is a kind of to improve the method that S. photeinocarpum repairs orchard cadmium pollution soil ability, comprise the following steps：
Mode is directly broadcasted sowing by Mine ecology type S. photeinocarpum kind in cadmium pollution orchard soil using direct transplanting or seed
In earth, after Mine ecology type S. photeinocarpum enters fast growing period, 1~20umol/L of the foliage-spray acid solution that comes off；Spray
Apply after at least 30 days, the aerial part of Mine ecology type S. photeinocarpum is gathered in.
Alternatively, the acid solutions that come off is 20umol/L.
As further selection, the method for preparing plant seedlings using direct transplanting method is as follows：
Under natural conditions, by the Mine ecology type S. photeinocarpum seedling directly transplanting being collected into cadmium pollution orchard soil
In, it is 15 × 15cm to control density.
As another further selection, the method that seed sowing mode prepares seedling is as follows：
Under field conditions (factors), the Mine ecology type S. photeinocarpum seed being collected into is seeded in cadmium pollution orchard soil,
Seedling grows rear even seedling, and density domination is in 15 × 15cm.
In such scheme, the Mine ecology type S. photeinocarpum refers to originate or is grown on the S. photeinocarpum in mining area.It is described
Fast growing period is generally after plantation one month, and the planting type of S. photeinocarpum is usually：Watering ensures that field soil moisture is held
Water is 80%, carries out the daily management of Mine ecology type S. photeinocarpum；The daily management includes even seedling, removes weeds.
Abscisic acid (abscisic acid, ABA), one kind suppresses growing plants hormone, is obtained because that can promote leaves
Name.Its main function has：Promote to come off, suppress growth, promote dormancy, the development for causing stomata to be closed, adjusting seed embryo, increase
Resistance and the differentiation of influence property.Wherein, as the use of increase resistance, the freeze proof ability of plant cold resistance is mainly strengthened, with
And improve the drought resistance and Salt-endurance of plant.
The mechanism of action：The physiological action of abscisic acid, which is mainly, causes dormancy and promotion to come off.With coming off, acid treatment plant gives birth to
Long vigorous sprig, can cause and dormancy identical state；The leaf for producing perula shape replaces the trophophyll of expansion；Reduce top
Hold the mitotic event of separate living tissue；And following leaves can be caused and the releasing of dormancy is prevented.With the acid treatment that comes off
The seed that can be sprouted, can be allowed to dormancy.This inhibitory action to sprouting can with gibberellin or the basic element of cell division processing come
Offset or reverse.The replacement long-day of abscisic acid energy antagonism gibberellin causes the effect that long day plant bolting is bloomed.It can also make
A small number of short day plants are bloomed under conditions of the non-induced cycle.Conversely, several effects of abscisic acid can also be offset with gibberellin.Example
Abscisic acid can be overcome to the elongation of the high stalk corn of heredity if using gibberellin and to seed sprouting and the suppression of potato sprouting
Make and use.In addition, the effect of abscisic acid is also with the basic element of cell division on the contrary, the work of abscisic acid existing antagonism gibberellin in plant
With also there is the antagonism basic element of cell division.But these antagonisms are extremely complex.For example Germination of Lettuce Seeds needs light,
Gibberellin can replace light.And abscisic acid can offset the effect that the promotion of gibberellin is sprouted, but continue to improve the dense of gibberellin
Degree can not but overcome the promotion of the effect, recovery of abscisic acid to sprouting.
Wherein, can be by guard cell's film mainly due to abscisic acid due to raising of the abscisic acid for Salt-endurance
Signal transduction, promote stomata to close, and the synthesis of induced resistance protein, while the expression of portion gene can be regulated and controled,
Strengthen the ability of plant resistant adverse circumstance with this.Therefore, in salt-soda soil, high concentration can be suppressed to common plant sprinkling abscisic acid
The absorption of sodium ion：On the one hand suppress excessive sodium ion into plant, on the other hand suppress sodium at high concentration ion pair other
The Competitive assays of soil nutrient elements so that other nutrients smoothly cover plant can absorb.Final result is to carry
Biomass of the high plant in salt-soda soil.
And toxic action of the heavy metal ion to plant, also similar salt-soda soil, because being all the metal ion of higher concentration：
On the one hand it is murder by poisoning to plant after heavy metal ion enters in plant, is on the other hand also heavy metal ion to other soil
The Competitive assays of nutrient.
And for heavy metal accumulation plant, but require the plant can as much as possible by heavy metal accumulation in internal,
Obviously from known knowledge, abscisic acid can suppress the process.
Therefore, although being commonly in the prior art in agricultural production, by spraying abscisic acid to improve the height of common plant
The resistance of concentration salt, but as previously described the reason for, never someone want by heavy metal enriching plant spray abscisic acid, with
The accumulation ability of its heavy metal ion is improved, it is particularly improved and transports coefficient, it is clear that this mutually deviates from existing knowledge.
Beneficial effects of the present invention：The present inventor is under study for action it was unexpectedly observed that to specific plant (S. photeinocarpum)
The abscisic acid (1~20umol/L) of particular type (Mine ecology type) sprinkling certain concentration can specifically improve it to specific
The accumulation ability of heavy metal ion (cadmium), especially more expects other places and improves its movement system so that originally and without notable
The S. photeinocarpum that meaning is repaired in cadmium pollution possesses real practical value.
