Abstract
The invention discloses a method for cleverly removing crofton weeds, which is characterized by selecting 30-50 g of 50% weedicide soluble powder glyphosate, optimally 50 g and 10 g of additive washing powder and adding 12.5 g of water. The compounded weedicide is uniformly sprayed to both faces of leaves of crofton weeds by using a sprayer based on the principle that the leaf faces are sprayed to be wet and no weedicide drops, and the spraying area is 200 m2. In the invention, the glyphosate weedicide is used for compounding with washing powder to cleverly removing crofton weeds, and the weedicide has good removal and treatment effects and convenience for use.
Description
Technical field
The present invention relates to the chemical method that going out of noxious plant removed, particularly a kind of skilful method of removing harmful instruction plant Eupatorium adenophorum
Background technology
Eupatorium adenophorum is one of invasion China and external pest of working the mischief; Work the mischief in China southwest, South China; Badly influence the development of farming, woods, fishing, animal husbandry, cause biological many property to fall sharply, land resources is seriously damaged.For preventing and kill off the harm of Eupatorium adenophorum, press for to visit and grind Eupatorium adenophorum and wipe out and treat insect pests and plant diseases and utilize measure.Because it is strong that the Eupatorium adenophorum rhizome is sprouted power, have only rhizome killed just can reach and wipe out and treat insect pests and plant diseases effect.Except the technology such as charcoal processing of utilizing Eupatorium adenophorum; Other most of technology are to utilize chemical method to wipe out and treat insect pests and plant diseases; " ternary mixed herbicide-weeding is clean " disclosed like Chinese patent 92106952.9; Chinese patent 96118250.4 discloses " weed killer herbicide ", and Chinese patent 97197694.5 discloses " method of controlling weeds ", and Chinese patent 95115635.7 discloses " preparation method of a kind of weed killer herbicide-" herbicide " "; These four patents have all been used the weed killer herbicide that contains glyphosate, also do not have glyphosate to add the patent or the report of washing powder weeding
Summary of the invention
the object of the present invention is to provide a kind of skilful method of removing Eupatorium adenophorum; This method adds washing powder in the glyphosate solvent; Wiring solution-forming evenly sprays in Eupatorium adenophorum blade tow sides, makes the withered rate of Eupatorium adenophorum higher; Have effective, the easy to use characteristics of wiping out and treating insect pests and plant diseases.
formation of the present invention: a kind of skilful method of removing Eupatorium adenophorum; Select weed killer herbicide-50% soluble powder glyphosate 30-50g for use; Add washing powder 10g, add water 12.5kg, will prepare medicament with sprayer and evenly spray in the tow sides of Eupatorium adenophorum leaf; Do not drip and be as the criterion to squirt the blade face, spray area 200m2.
above-mentioned weed killer herbicide-50% soluble powder glyphosate the best is 50g.
above-mentioned method can also be removed grass family and other weeds.
can know that from above technical scheme the present invention adds washing powder in glyphosate, and wiring solution-forming evenly sprays in Eupatorium adenophorum blade tow sides, make the withered rate of Eupatorium adenophorum high, easy to use.
Embodiment
Through test the present invention is described further below
.
1, materials and methods
1.1 supply examination weed killer herbicide and additive
Weed killer herbicide: glyphosate (50% soluble powder)
Additive: washing powder
1.2 concentration preparation
First group: add water 12.5kg respectively by 30g, 40g, 50g
Second group: add washing powder 10g and water 12.5kg respectively by 30g, 40g, 50g
1.3 application method
Eupatorium adenophorum height, cover degree, the identical plot of distribution consistency degree are chosen in
; Power driven sprayer with the production of Linyi, Shandong machinery plant; To prepare medicament and evenly spray, and not drip and be as the criterion, spray area 200m2 to squirt the blade face in Eupatorium adenophorum blade tow sides.
1.4 investigation method
investigation factor: the situation of change of observed and recorded root, stem, leaf after the dispenser, the withered amount of 28d investigation statistics root, stem, leaf and other non-target plant damage situations.Eupatorium adenophorum newly sprouts situation on 60d investigation dispenser appearance ground.
investigation method and test are provided with: 2 with laying 10m * 10m appearance in variable concentrations different disposal dispenser plot, in the test location 2 on control samples ground is set, and contrast is handled with clear water, specification 10m * 10m.The mode of taking plum blossom to layout is laid 1m * 1m and is investigated 5 in sample prescription, and random searching 30 strains in the sample prescription are listed and decided the strain investigation.1d, 3d, 7d, 12d, 21d, 25d, 30d observe after the dispenser, and the wilting or the withered situation of statistics leaf, stem are measured the withered length of stem, and the investigation root kills and wounds situation.Behind the dispenser 60d, Eupatorium adenophorum newly sprouts the strain number in the investigation appearance ground, confirms at last to kill except that effect.
effect inspection and purpose: because that the Eupatorium adenophorum rhizome is sprouted power is strong, has only rhizome killed just can reach and wipe out and treat insect pests and plant diseases effect, therefore, this test is quoted the strain preventive effect and is weighed medicament and wipe out and treat insect pests and plant diseases effect.
1.5 statistics and evaluation criterion
Strain put effect (%)=
PT is the remaining Eupatorium adenophorum plant of a treatment region number
CK is that blank removes Eupatorium adenophorum strain number alive
evaluation criterion:, be divided into excellent, good, effective, invalid four grades according to the withered amount of strain preventive effect, leaf of wiping out and treating insect pests and plant diseases Eupatorium adenophorum after the dispenser, the withered length of stem.Excellent: strain preventive effect>=80%, plant root, stem, leaf are withered; Very: strain preventive effect 60～80%, leaf are all withered, and big of stem is withered, and root portion is withered; Effectively: strain preventive effect 30～60%, leaf are all withered, and stem is withered, and root portion is withered; Invalid: strain preventive effect≤30%.
2, result and analysis
Here withering appears in
glyphosates (50% wetting powder) 3d Eupatorium adenophorum plant after dispenser, all yellow to the 7d leaf, pushes up witheredly slightly, and rhizome is withered will to last till 25d.Grass family and other weeds are had kill efficacy equally, but shrub is influenced little, and a poisoning is arranged, can normal growth.Behind dispenser 60d, appearance is covered with other weeds in the ground, and weeds cover degree average out to is more than 80%, and chemistry is wiped out and treated insect pests and plant diseases and caused ecological disruption under the effect of natural force and soil seed bank, soil seed pool, to be able to repair.
Wipe out and treat insect pests and plant diseases statistical effect such as table 1:
Interpretation of result:
Can know that from above test data glyphosate adds washing powder, and to wipe out and treat insect pests and plant diseases the effect of Eupatorium adenophorum better than what do not add, 50g soluble glyphosate pulvis+10g washing powder+12.5kg water prescription to wipe out and treat insect pests and plant diseases effect best, withered rate is up to 95.33%.
