Description

It is a kind of to inhibit Eupatorium adenophorum growth and complexing agent of competition and preparation method thereof
Technical field
The invention belongs to field of biological control, specifically a kind of complexing agent and its system for inhibiting Eupatorium adenophorum growth and competition Standby and application method.
Background technique
Eupatorium adenophorum is commonly called as destroying grass, the malignant weed for being that a kind of vitality is strong, breeding potential is high and being difficult to clean off, at me It ranks the first in the first batch of Invasive Alien Species ranks of state.It inhibits the growth of surrounding plants, and soil fertility is caused to decline, soil It degenerates, brings high risks to crop growth, livestock cultivation.For many years, relevant departments by chemical control, biological control and The multiple means such as processing and utilization inhibit Eupatorium adenophorum sprawling, but produce little effect always.
Eupatorium adenophorum is herbaceos perennial, originates in Central America, after the forties in last century introduces China from Burma, no Disconnected diffusive transport, has occupied a large amount of old-field, Rehabilitated land, arable land and forest land etc., brings to local agricultural and forestry Huge threat and destruction.Develop into sociales in some natural ecosystems, endangers bio-diversity and ecosystem The structure and function of system.Eupatorium adenophorum can secrete allelochemical, inhibit the growth of neighboring plants, and can change soil fungi, It improves the competitiveness.The instruction plant is also toxic, and livestock, which is eaten by mistake, easily causes poisoning.Since it is greatly negatively affected, purple stem Herba Lycopi is listed in one of the invasive species that China most endangers.The species are also to the U.S., Australia and much Africa and Asia Continent country has the malignant weed of harmfulness.
It is more studies have shown that Eupatorium adenophorum relative growth rate with higher and biggish biomass, and can pass through Allelopathic influences the influence with fungi to improve the competitiveness, and successfully invades.Eupatorium adenophorum secretes allelochemical, inhibits many locals The Seed Germination and growth of plant, moreover, its secretion allelochemical, can long-term existence in soil.Eupatorium adenophorum can also Change the fungi in invasion ground soil, growth and Competition conducive to itself.In addition, the seed of Eupatorium adenophorum can stay for a long time It is stored in soil, when condition is suitable for, then sprouts and generate new plant.
Currently, many methods include the control that Chemical Control, biological control and Mechanical course are all applied to Eupatorium adenophorum In.In contrast, substitution control is due to becoming optimal selection with safety, the feature of environmental protection, economy and sustainability.But It is, since Eupatorium adenophorum can secrete allelochemical into soil, even if these allelochemicals still may be used after removing Eupatorium adenophorum It retains at least 2 years or more in the soil；Eupatorium adenophorum can generate a large amount of seed, and these seeds can form permanence Seed bank can also be sprouted out again, generate Competition with substituted plant again.Therefore simple removal Eupatorium adenophorum cannot be true Protect the ecological recovery success on invasion ground.This allows for substitution control and not only needs to inhibit the growth of Eupatorium adenophorum, and also to lead to The influence for weakening its allelopathic influence and soil fungi is crossed, its Competition to substituted plant is reduced, can be only achieved the purple stem of control Herba Lycopi restores the purpose of ecology.
Some eciophytes are able to suppress the sprouting and growth of instruction plant, can develop as natural inhibitor.Activity Charcoal can adsorb the secondary metabolites of plant.Fungicide can kill fungi, remove its influence.But to being at present Only, lack the growth that Eupatorium adenophorum is reduced using spontaneous growth inhibitor, and simultaneously by weakening its allelopathy and fungi shadow The effect of sound reduces the research of its competitiveness.

The pulvis no pollution to the environment of tea wood strip leaf is pure natural plant component, can reduce the seed of Eupatorium adenophorum It sprouts and plant height, the number of blade, total leaf area, relative growth rate, total biomass and competitiveness.
Since Eupatorium adenophorum invasion can change soil fungi, to improve the competitiveness of Eupatorium adenophorum, addition is killed true After microbial inoculum, the effect of the soil fungi of Eupatorium adenophorum mediation can be reduced, the competitiveness of Eupatorium adenophorum is influenced.
The present invention inhibits the preparation method of the complexing agent of Eupatorium adenophorum growth and competition, plants by every kg soil addition 37.5g Material resource growth inhibitor adds 37.5-62.5g active carbon, is first uniformly mixed plant source growth inhibitor and active carbon, mixes 0.15-0.47g fungicide is added by every kg soil again afterwards, is mixed evenly to prepare complexing agent again.
Inhibit Eupatorium adenophorum growth and competition at present, be out of use complexing agent, is only improved with single formulation active carbon Soil, or with the single killing soil fungi of fungicide, reduce the influence of fungi.And with complexing agent, Eupatorium adenophorum can be inhibited Growth, improvement soil remove the allelopathy of Eupatorium adenophorum, and can kill soil fungi, reduce the competition of Eupatorium adenophorum, improve The growth and competition of eciophyte effectively restore the ecology on invasion ground.
Complexing agent of the present invention filter out inhibit Eupatorium adenophorum plant source growth inhibitor, with active carbon, again with it is antifungal Complexing agent is made according to different dosage in agent, can inhibit Eupatorium adenophorum growth and competition but invasion ground soil.It keeps away Exempt from the residual of chemical prevention in the soil to the pollution and Eupatorium adenophorum allelochemical of ecological environment, improves the competition of eciophyte Ability promotes the recovery of eciophyte, and the ecological recovery of control and invasion ground for Eupatorium adenophorum plays a significant role.
