Embodiment 1

[0033] Embodiment 1 Different planting periods substitute species to the competitive action of airplane grass

[0034] Test materials: 20 days, 40 days and 60 days after emergence of the aircraft grass seedlings, ryegrass seedlings, Artemisia annua seedlings, alfalfa seedlings, Artemisia annua seedlings, Kochia seedlings, Setaria wrinkled leaves seedlings grown 40 days after seed emergence , sunflower seeds and diced Jerusalem artichoke with 1 eye bud.

[0035] Test method: adopt the addition series design with the density of planegrass fixed and the density of each competing species increase, set up 8 treatment plots in the solar greenhouse, repeat 4 times for each treatment, the plots are arranged completely randomly, and the density of planegrass in each treatment is according to 4250 plants Planting per mu, the density of each competing species is planted at 8500 plants / mu, and each treatment is transplanted to the corresponding competing alternative species on the 20th da...

Embodiment 2

[0061] Example 2 Competitive effect of cut pieces of Jerusalem artichoke with 1 bud eye and plane grass under different densities

[0062] Test materials: Airplane grass grown for 40 days after emergence, cut pieces of Jerusalem artichoke with 1 bud eye.

[0063] Test method: In the solar greenhouse, adopt the addition series design with the density of the plane grass fixed and the density of the competing species increased. The plane grass seedlings were grown for 40 days, and the cut pieces of Jerusalem artichoke with 1 bud eye were planted between the plane grass seedlings according to the following planting density. The planting density of aircraft grass is respectively by 4250 strains / mu, 5250 strains / mu, 6250 strains / mu and 7250 strains / mu, and the planting density of described Jerusalem artichoke cuttings is respectively pressed by 8500 strains / mu, 10500 strains / mu, 12500 strains respectively / mu and 14500 plants / mu, the contrast of Jerusalem artichoke and plane grass i...

Embodiment 3

[0070] Example 3 Competitive effect of cut pieces of Jerusalem artichoke with 2 to 3 bud eyes and plane grass at different densities

[0071] Test materials: Airplane grass grown for 40 days after emergence, cut Jerusalem artichoke with 2 bud eyes and cut Jerusalem artichoke with 3 bud eyes.

[0072] Test method: In the solar greenhouse, the density of aircraft grass was fixed and the density of competing species was increased.

[0073] Airplane grass emerges and grows for 40 days, and the planting density of airplane grass is 4250 plants / mu. The planting density of the cut pieces of Jerusalem artichoke with 2 bud eyes is correspondingly respectively 6250 plants / mu, 7250 plants / mu, 8250 plants / mu, and 9250 plants / mu. Plants / mu, 10250 plants / mu and 11250 plants / mu, the planting densities of cut Jerusalem artichokes with 3 bud eyes are respectively 4250 plants / mu, 5250 plants / mu, 6250 plants / mu, 7250 plants / mu, 8250 plants / mu and 9250 plants / mu, the Jerusalem artichoke cut pie...

Abstract

The invention relates to the technical field of replacement prevention and control of alien invasive pests, in particular to a method for replacing and controlling eupatorium odoratum through jerusalem artichoke. According to the method for replacing and controlling the eupatorium odoratum through the jerusalem artichoke, by reasonably planting jerusalem artichoke dices with 1-3 bud eyes, the control effect of the eupatorium odoratum can reach 66% or above, the control effect lasting for 24 months is larger than 95%, and an efficient, safe and lasting replacement control technology system is generated.

Description

technical field [0001] The invention belongs to the technical field of alternative prevention and control of alien invasive harmful organisms, and in particular relates to an alternative control method for major alien invasive harmful organisms planeweed. Background technique [0002] Chromolaena odoratum (L.) R.M.King&H.Robinson), also known as Chromolaena odoratum (L.M.King&H.Robinson), is a clustered perennial herb or subshrub of the genus Chromolaena odoratum in the family Asteraceae. It is native to Central and South America, and is now widely distributed in Africa, Most of the tropical and subtropical regions of Asia, Oceania and the Western Pacific Islands. In China, it entered southern Yunnan for the first time through the borders of China-Myanmar and China-Vietnam in the 1930s, and then spread and spread rapidly. At present, it is widely distributed in Yunnan, Hainan, Guangdong, Guangxi, Hong Kong, Macao and other southern provinces. [1,2] . Airplane grass is reco...
