Description
Technical field
The present invention relates to herbicide technology field, particularly relate to a kind of preparation method of highy potent herbicide.
Background technology
The problems such as the environmental pollution brought along with chemosynthesis weed killer herbicide, tolerant weeds population are risen, the appearance of antiweed weeds and poisoning are day by day serious, and apply traditional random synthesis filtering mode successfully to develop the probability of novel herbicide also more and more less in addition.Therefore, from the biologies such as natural plant, find the natural materials with activity of weeding and become one of important channel of development environment friendly weed killer herbicide.
Found that the plant of section more than 30 contains the native compound that nearly hundred kinds have herbicide effect at present, wherein some is developed to natural herbicide.Although develop in weed killer herbicide utilizing natural products and achieve certain achievement, with people, plant insecticide is compared with the degree of concern of bactericide, relatively less to the research and development of botanical herbicides.And often botanical herbicides cooperatively interacts, and coordinate with chemical herbicide and can produce synergistic effect, improve weeding ratio.Now find a kind of chemical herbicide relative to prior art with more high herbicidal efficiency.
Summary of the invention
Based on the technical problem that background technology exists, the present invention proposes a kind of preparation method of highy potent herbicide, gained weed killer herbicide weeding ratio is high, little to the destruction of environment, and can reduce the drug resistance of weed population.
The preparation method of a kind of highy potent herbicide that the present invention proposes, comprises the steps:
S1, dry to moisture by twigs of the chaste tree flower, erigeron, the leaf of pepper, Conyza canadensis to be 20-25wt%, then to pulverize, cross 100-120 mesh sieve, drying obtains the first material; Added in ethyl acetate by first material and mix, after then carrying out sonic oscillation extraction, suction filtration, concentrated obtain first and slightly gets thing;
S2, cleaned by the root of the root of Trifolium repense, the leaf of lilac and chrysanthemum peach, drying to moisture is 10-15wt%, then pulverizes, and crosses 100-120 mesh sieve, then be placed in water, then add complex enzyme formulation and mix, leave standstill, go out enzyme, suction filtration, concentrated obtain second and slightly get thing;
S3, slightly to get thing and second by first and slightly get and carry out reduction vaporization after thing mixes and obtain active material;
S4, active material, Tea Saponin, lemon, haloxyfop, emulsifier, dispersant, thickener, structure regulator, antioxidant, preservative and soybean oil are mixed after obtain highy potent herbicide.
Preferably, in S1, the leaf of twigs of the chaste tree flower, erigeron, pepper, the weight ratio of Conyza canadensis are 50-100:20-40:40-80:10-30.
Preferably, in S1, baking temperature is 50-60 DEG C, and drying time is 5-8h.
Preferably, in the sonic oscillation extraction of S1, supersonic frequency is 0.22-0.25MHz, ultrasonic power 700-800W, and hunting speed is 150-180rpm.
Preferably, in S2, the weight ratio of the root of the root of Trifolium repense, leaf of Syringa oblata Lindl and chrysanthemum peach is 10-20:50-70:20-40.
Preferably, in S2, comprise by weight in complex enzyme formulation: 4-8 part cellulase, 5-6 part pectase, 2-3 part protease.
Preferably, adopt microwave deactivating enzyme in S2, microwave power is 700-1000W.
Preferably, in S3, first slightly to get the weight ratio that thing and second slightly gets thing be 3-5:2-4.
Preferably, in S4, the weight ratio of active material, Tea Saponin, lemon, haloxyfop, emulsifier, dispersant, thickener, structure regulator, antioxidant, preservative and soybean oil is 60-80:30-40:5-15:10-16:5-8:2-3:3-5:1-3:0.5-1.5:0.5-1.5:1 00.
Preferably, structure regulator is one or more compositions in zeolite powder, imvite, kaolin.
Ethyl acetate in above-mentioned S1 and the water in S2 are only solvent, do not affect reaction and carry out, without the need to the consumption of both restrictions.
The present invention adopts twigs of the chaste tree flower, erigeron, pepper leaf and Conyza canadensis to coordinate, and carries out sonic oscillation extraction by adding in ethyl acetate, is leached by the active component of twigs of the chaste tree flower, erigeron, pepper leaf and Conyza canadensis oil-soluble; And adopt Trifolium repense, lilac and chrysanthemum peach to coordinate, obtain water extraction in Trifolium repense, lilac and chrysanthemum peach by enzymolysis; Then mix reduction vaporization and obtain active material, the allelochemical namely in above-mentioned material, can produce the effects such as genetoxic for weeds, thus reaches the effect of weeding; And active material and Tea Saponin, lemon, haloxyfop cooperatively interact, not only act on weeds simultaneously, toxicity is produced to weeds, surface tension of the present invention can also be reduced, improve the wet exhibition power of the present invention on weeds and adhesive force, significantly improve the deposition of the present invention on grass cutting blade surface, thus improve drug effect.
