Description
Technical field
The present invention relates to the combination biochemical methods that a kind of enhancing phytoremediation pollutes efficiency.
Background technology
With the development of industry, environmental pollution getting worse.Phytoremediation technology is self-produced as a pollutant abatement technology
Extensive attention has just been received since life, it have it is at low cost, small to environmental perturbation, multiple pollutant, U.S. can be handled simultaneously
The features such as changing environment；But for repairs pollution environment the usual biomass of plant it is low, slow-growing, growth cycle is long, thus plant
Object is to the less efficient of pollution amelioration.The reinforcement technique for having phytoremediation utilizes biology, chemistry, physics also for problem above
Etc. means cultivate fine seed strains, change the existing forms of pollutant, improve the growing environment of plant, to improve plant to pollutant
Repair ability cultivates the ultraproduct suitable for a wide range of commercial growth such as plant-microorganism United Technologies using biotechnology
Tired plant improves concentration of the pollutant in environment solution to be conducive to phytoremediation etc. using chemical assistant.But this
Or a little methods are more complicated or the period is long or bring secondary pollution.So being badly in need of that simple, easily method carries
High phytoremediation pollutes efficiency.
Invention content
The invention solves critical issue be improve rehabilitation plant the speed of growth, increase its biomass, to improve
Phytoremediation pollutes efficiency.The terminal bud preferred growth of plant and the suppressed phenomenon of lateral bud is known as apical dominance.Most plants
There is apical dominance phenomenon, but the form and degree that show are different because of floristics.The strong plant of apical dominance, it is hardly estranged
Branch；Apical dominance is weak, can grow many branches.Meanwhile most of widely applied rehabilitation plant is clone plant, stem now
Duan Yanshen is mainly regulated and controled by gibberellin.So the present invention is by combining biochemical method removal plant tip advantage and promoting stem section
Extend, plant lateral bud can be promoted to sprout, increase side shoot number or promote collateral generation, and rapidly promote stem section and extend growth,
The extensive covering that plant can not only be fast implemented, is also greatly improved phytomass, pollutes efficiency to improve phytoremediation.
The technical solution adopted in the present invention is：A kind of combination biochemical method of enhancing phytoremediation pollution efficiency, is logical
The biochemical reagents crossed the biochemical reagents that removal plant tip advantage is applied in combination and stem section is promoted to extend quickly promote plant life
Length is expanded and increases significantly phytomass, pollutes efficiency to improve phytoremediation.
Preferably：
Handle Season select：According to plant growth characteristics, processing season is determined.General 1-3 times annual, wherein south can 1-
3 times (spring, summer, autumns), the north can 1-2 times (spring, summers).
Processing time selects：According to weather forecast, the specific time of processing was preferably selected at the cloudy day, convenient for plant itself profit
With, repair and growth.
Plant treatment：Plant hormones and the basic element of cell division sample plant growth tune such as the basic element of cell division are selected according to different condition
Section agent etc. is combined biochemical reagents with the use of the plant hormones such as gibberellin and gibberellin sample plant growth regulator etc. and is planted to remove
Object apical dominance promotes stem section to extend.
The plant hormones such as the basic element of cell division and basic element of cell division sample plant growth regulator etc. are with the use of plants such as gibberellin
The biochemical reagents usage and dosage such as object hormone and gibberellin sample plant growth regulator is according to its specification.
5) conventional maintenance：Operation standard conventional maintenance rehabilitation plant as requested.
Relative to other methods and technology, advantage of the invention essentially consists in simple, quick, of low cost, easy construction,
It can be widely used in phytoremediation environmental pollution project or engineering.
