Embodiment 1

[0028] Example 1 Competitive effect of substitute species on Mikania micrantha in different planting periods

[0029] Test materials: Mikania micrantha seedlings grown for 10 days, 30 days and 50 days after emergence, single sweet potato seedlings with a length of 5-7cm after cutting for 10 days, tall fescue seedlings, ryegrass seedlings, and Artemisia annua grown for 20 days after emergence Seedlings, wrinkled dogtail seedlings, miscellaneous clover seedlings, alfalfa seedlings, lentil seedlings grown for 7 days after emergence

[0030] Test method: adopting the addition series design of Mikania micrantha density fixed and increasing density of competing species, 8 treatment plots were set up in the solar greenhouse, and each treatment was repeated 4 times. Planting, the density of each competing species was planted at 13,000 plants / mu, and each treatment was transplanted to the corresponding competitive alternative species on the 10th, 30th and 50th day after Mikania micrant...

Embodiment 2

[0058] Competitive effect of sweet potato and Mikania micrantha under different densities of embodiment 2

[0059] Test materials: Mikania micrantha grown for 30 days after emergence, and single-segment sweet potato seedlings with a length of 5-7 cm cut for 10 days.

[0060] Test method: In the solar greenhouse, the density of Mikania micrantha was fixed and the density of competing species was increased. The Mikania micrantha seedlings were grown for 30 days, and the cuttings were planted between the Mikania micrantha seedlings at the following planting density for 10 days. Festival sweet potato seedlings: the planting density of Mikania micrantha is planted at 6500 plants / mu, 7500 plants / mu and 8500 plants / mu respectively, and the planting density of the sweet potato seedlings is respectively 13000 plants / mu, 15000 plants / mu and 17000 plants / mu Planting, the control of sweet potato and Mikania micrantha was a single treatment at the corresponding density level, the plots wer...

Embodiment 3

[0067]Example 3 The field substitution control effect of sweet potato to Mikania micrantha

[0068] Test materials: Mikania micrantha grown for 30 days after emergence, and single-segment sweet potato seedlings with a length of 5-7 cm cut for 10 days.

[0069] Experimental Design: The experiment was conducted in Longchuan County, Dehong Prefecture, Yunnan Province in 2010. Before the experiment, a sweet potato field with Mikania micrantha in previous years and higher water and fertilizer conditions was selected as the experimental field. The test adopts the addition series design of fixed Mikania micrantha density and increased sweet potato density. The planting density of Mikania micrantha is 6500 plants / mu, and the planting densities of sweet potatoes are 6500, 13000, 17000 and 19000 plants / mu respectively. single treatment. Residential Area 30m 2 , 4 repetitions per treatment, completely randomized block design. Calculate the number of sweet potatoes planted per acre ac...

Abstract

The invention discloses a method of utilizing replacement control and herbicide application to control mikania micrantha, and belongs to the technical field of comprehensive prevention and control to the exotic invasion pest. The method comprises the following steps: when mikania micrantha is emerged and grows for 30 days, planting and sticking simple-link sweet potato seedlings with length of 5-7 cm for 10 days between the mikania micrantha seedlings, and at the same time, spraying bentazone at the dosage of 48-72 g/mu. Compared with the single application of bentazone, 60-90 days after administration, the control effect is improved by 2.52-20.44%; compared with the single sweet potato replacement control, 60-90 days after administration, the control effect is improved by 14.12-38.39%; compared with the single application of bentazone at the dosage of 72 g/mu, the dosage is reduced by 33% when the planting density ratio of the sweet potato to mikania micrantha is 2.6:1, and the control effect is improved by 0.2-1.51%, 60-90 days after administration. The method has the characteristics of high efficiency, safety and long-lasting control.

Description

technical field [0001] The invention belongs to the technical field of comprehensive prevention and control of alien invasive pests, and specifically relates to an alternative control method and a chemical control method for major invasive alien pests Mikania micrantha, and an efficient, safe and durable control of mikania micrantha established by performing alternative control combined with the application of herbicides comprehensive control technology system. Background technique [0002] Mikania micrantha (Mikania micrantha H.B.K) is a perennial herbaceous or slightly woody climbing plant belonging to the family Asteraceae. It is native to South America and Central America, and has been widely spread to South Asia, Southeast Asia, the Pacific and other regions. One of the most harmful tropical and subtropical weeds [1,2] . At present, Mikania micrantha spreads and breaks out in Guangdong, Yunnan, Hainan, Guangxi, Hong Kong and other places in my country. Its invasion ha...
