Among them, physical control is difficult to eradicate and easy to relapse; chemical control is easy to pollute the ecological environment; biological control costs are high and take a long time; community transformation is more beneficial to the ecological restoration of Mikania invasive sites, but its cost is high and the operation is complicated, which affects the technical level. Higher requirements for knowledge and knowledge restrict the large-scale promotion and application of such methods

Embodiment example 1
[0035] Implementation case 1: The control effect of different combinations of atrazine, atrazine and ethephon on Mikania micrantha in vigorous growth period
[0036] 50% atrazine suspension concentrate, 50% atrazine suspension concentrate and 40% ethephon water solution were formulated into different herbicides according to the formulations in Table 1, and then mixed with water to 600-675L. The treatment group 1 with clear water was used as the control group (see Table 1).
[0037] Select the thicker branches of Mikania micrantha in the current year and cut every 2 nodes into one section, and plant them in flowerpots with a diameter of 11.5cm x a height of 10cm, one plant per pot, when the stem length of the Mikania micrantha plant is 130-150cm (that is, the vigorous growth period) time for testing.
[0038] Use the spray method. Use a quantitative sprayer to evenly spray the stems and leaves of Mikania micrantha, and the spray volume is 600-675L / hm 2, 20 pots of Mikania mi...

[0046] Implementation case 2: Control effect of different combinations of atrazine, atrazine and ethephon on the flowering stage of Mikania micrantha
[0047] 50% atrazine suspension concentrate, 50% atrazine suspension concentrate and 40% ethephon water solution were formulated into different herbicides according to the formulations in Table 1, and then mixed with water to 600-675L. The treatment group 1 with clear water was used as the control group (see Table 1).
[0048] Choose the thicker branches of Mikania micrantha in the current year and cut every 2 nodes into one section, plant them in flower pots with a diameter of 11.5cm×10cm in height, one plant per pot, and use them for testing during the flowering period of Mikania micrantha.
[0049] Use the spray method. Use a quantitative sprayer to evenly spray the stems and leaves of Mikania micrantha, and the spray volume is 600-675L / hm 2 , 25 pots of Mikania micrantha were treated, and the experiment was repeated three ...

Abstract
The invention discloses an ethephon-containing herbicide for preventing and removing mikania micrantha and application of the ethephon-containing herbicide, belonging to the field of prevention and control of invasive plants. Effective components in the herbicide disclosed by the invention are composed of ametryn, atrazine and ethephon in a mass ratio of 100: 40: (0.875-7). According to the invention, the physiological regulation effect of ethephon on plants is utilized so as to improve the conductivity of the herbicide ametryn and the herbicide atrazine in a plant body and allow compounding of ametryn and atrazine to produce an obvious synergistic effect, so the usage amount and the spraying frequency of the herbicides are reduced, manpower and material resources are saved, reliable guarantee can be provided for effectively removing mikania micrantha in a large-area field invaded by mikania micrantha, and good ecological benefits and economic benefits are achieved. An operation methodfor the ethephon-containing herbicide is simple and convenient; and the ethephon-containing herbicide is suitable for large-area popularization and application in mikania micrantha-invaded places, accelerates the prevention and removal of mikania micrantha, and better promotes the improvement and recovery of the ecological environment of the mikania micrantha-invaded places.
Description
technical field [0001] The present invention relates to the field of prevention and control of invasive plants, in particular to a medicament for preventing and controlling Mikania micrantha containing ethephon and its application, specifically a combination of atrazine and ethephon to improve the control effect on Mikania micrantha, Reduce the amount of herbicides used and the frequency of spraying. Background technique [0002] Mikania micrantha Kunth (Mikania micrantha Kunth), also known as Eupatorium micrantha or Eupatorium florida, is a perennial herbaceous vine of the genus Eupatorium in the Asteraceae family. It is native to Central and South America and is now widely distributed in Southeast Asia and the Pacific Ocean. area, one of the top ten harmful weeds in the world. Mikania micrantha has extremely strong asexual reproduction and sexual reproduction ability, and is known as the "one-minute British weed". Mikania micrantha is light-loving by nature, and likes fe...
