The method is easy and convenient to operate, high in extraction efficiency, environmentally friendly, free of organic solvents and pure water and suitable for popularization of basic forest farms and nursery gardens, and high-value utilization of mikania micrantha is achieved.

The present invention discloses a construction method of a disturbed green space Callicarpa oleracea community, comprising the following steps: S1. preparing Callicarpa oleracea dead leaves: plucking fresh Callicarpa oleracea leaves, drying them in an oven, compressing and packing them for storage; S2. arranging the disturbed green space: removing weeds and gravel from the disturbed green space, plowing 5-10cm, sprinkling Callicarpa oleracea dead leaves to cover, watering and soaking the dead leaves, and then covering with a black film for 3-5 days. S3. planting Callicarpa oleracea: removing the black film, selecting Callicarpa oleracea of ​​a pioneer tree species with a plant height of 1.5-3 meters; after 6 months of field planting, applying compound fertilizer once, conventional watering and pest control; S4. after an interval of 1 year, pruning dry or weak branches in the forest, planting shrub Callicarpa oleracea in the plant forest and forest edge, and planting transition plants at the edge of the planting area. The present invention utilizes the allelopathic effect of the plant itself to prevent Mikania micrantha from breeding; adopting the concept of pioneer tree species, first planting fast-growing, barren-resistant and native (domestic) species, and resisting the spread of Mikania micrantha in the early stage through the growth rate advantage.

The application relates to the technical field of plant invasion prevention, and discloses application of aikenol monomethyl ether in inhibition of growth of Mikania micrantha. The aikenol monomethyl ether is dissolved in dimethyl sulfoxide, and then a 1200 microgram / mL mother liquor is prepared by using purified water; 1.333 mL of the mother liquor with a concentration of 1200 microgram / mL is taken in a clean container, and purified water is added to make up to 40 mL, so that 40 mL of aikenol monomethyl ether solution with a concentration of 40 microgram / mL is obtained; the aikenol monomethyl ether solution is sprayed on Mikania micrantha plants with 4-6 leaves; purified water is sprayed as a control; and on the fifth day, the difference in plant height between the treatment group and the control group is obviously observed. Therefore, the aikenol monomethyl ether can be used for preparing a medicine for inhibiting the growth of Mikania micrantha, so that the growth of Mikania micrantha is inhibited.

The invention provides mikania micrantha dry powder as well as a preparation method and application thereof, eel feed as well as a preparation method and application thereof, and relates to the technical field of aquaculture. Specifically, to-be-fermented mikania micrantha powder is prepared from fresh mikania micrantha stalks and leaves, mikania micrantha zymophyte powder is prepared from fresh mikania micrantha leaves and cotton aphid adults, then mikania micrantha zymophyte liquid and a mikania micrantha liquid fermentation culture medium with specific components are prepared respectively, and the novel mikania micrantha dry powder is obtained through fermentation culture. In addition, the novel eel feed is prepared from mikania micrantha dry powder, white fish meal, alpha-starch, choline chloride, calcium hydrophosphate, fish oil, a compound additive, compound vitamins, compound minerals and an adhesive. The problems of eel fry breeding, artificial breeding and bait supply can be solved, and the artificial eel breeding cost is greatly reduced.

The utility model relates to the technical field of unmanned aerial vehicles, in particular to a mikania micrantha positioning spraying device for an unmanned aerial vehicle, which comprises an unmanned aerial vehicle body, a plurality of groups of fan blades are fixedly mounted on the front side and the rear side of the unmanned aerial vehicle body, a protective cover is fixedly connected to the bottoms of the fan blades, and a pesticide storage box is fixedly connected to the bottom of the unmanned aerial vehicle body. The bottom of the pesticide storage box fixedly communicates with a plurality of sets of connecting pipes, the bottoms of the connecting pipes fixedly communicate with pesticide conveying pipes, a transfer box communicates between the two sets of pesticide conveying pipes, the ends, away from the transfer box, of the pesticide conveying pipes are fixedly connected with a mounting frame, and the front side and the rear side of the mounting frame are fixedly connected with undercarriages. According to the mikania micrantha pesticide spraying device, by adjusting the spraying angle and the spraying amplitude of the pesticide, the pesticide can be accurately sprayed to the growth position of mikania micrantha, it is avoided that when the pesticide is sprayed to mikania micrantha, other plants nearby are damaged, and the ecological environment is protected.

The invention discloses an application of a Mikania micrantha (Mikania micrantha) extract in preparation of an antihistamine drug. Researches show that the mikania micrantha extract has activity of antagonizing histamine receptors, can improve symptom reactions of model animals constructed by specific histamine receptor agonists, blocks combination of histamine and receptors, and inhibits histamine from exerting biological effects; the mikania micrantha volatile oil and the mikania micrantha aqueous extract have good antagonism effects, have H1 and H4 receptor antagonism activity and can relieve symptoms caused by combination of histamine H1 or H4 receptors and histamine, and the relieving effect of the mikania micrantha volatile oil and the mikania micrantha aqueous extract is equivalent to that of positive drugs. The mikania micrantha extract is used as a histamine receptor blocker, can act on different histamine receptors at the same time and has good antagonistic activity, and more methods and bases are provided for preparing more natural, safe and efficient antihistamine drugs.

The invention discloses an application of a camptothecin derivative as a herbicide. The research shows that the camptothecin derivatives hydroxycamptothecin, 7-ethyl-10-hydroxycamptothecin and 9-aminocamptothecin have obvious inhibition effects on root growth and plant growth of various common typical weeds, have relatively broad-spectrum herbicidal activity, comprise dicotyledonous weeds such as amaranthus retroflexus, bidens pilosa, mikania micrantha, ageratum conyzoides, feather cockscomb and mimosa pudica, and have broad-spectrum herbicidal activity, such as amaranthus retroflexus, bidens pilosa, mikania micrantha, ageratum conyzoides, feather cockscomb and mimosa pudica. Moreover, the weeding effect is remarkable, and the weeding composition is superior to the weeding agent glyphosate which is most commonly used in agriculture; and the compound is derived from natural plants, is high in ecological safety and environment-friendly, and has very good application value and prospect in the aspect of developing herbicides. Furthermore, the camptothecin derivatives can be applied to field production through dosage form processing, and have the advantages of environmental protection and efficient utilization of resources.
