Problems solved by technology

(2) Using chemical control methods such as herbicides, this method can control the invasion of large areas of alien plants, but there is a hidden danger of polluting the environment with a large amount of chemical substances
(3) Introduce natural enemies from the origin of exotic plants to control exotic weeds. This biological control method can prevent and control malignant invasive weeds on a large scale, but there are new changes in biological control agents after the introduction that cause new hazards
Artificial control methods and chemical control methods are only effective for a short period of time

Embodiment 1

[0032] Plant Material: Green Weed ( Celosia argentea ), Yellow Vanilla Osmanthus ( Melilotus officinalis ) and red thistle ( Ageratum conyzoides ).

[0033] Other materials: straw clippings and straw ash.

[0034] The implementation steps are as follows:

[0035] (1) First prepare the mixed matrix according to the weight ratio: 80% of straw clippings and 20% of straw ash.

[0036] (2) Control experiment of Shenghongji: In March 2009, an experimental sample plot was selected from the abandoned farmland around the manganese mine, and various plants in the sample plot were eradicated to create planting holes. The direction of the rows is the same; the distance between two adjacent planting holes in the same row is 30 cm, and the distance between two adjacent plant rows is 30 cm. 1.0 kg of mixed substrate was applied to each plant hole. Matching planting: plant the two plants of green scallops and yellow vanilla osmanthus in the same row by interplanting, and insert the r...

Embodiment 2

[0041] Plant Material: Green Weed ( Celosia argentea ), Yellow Vanilla Osmanthus ( Melilotus officinalis ) and red thistle ( Ageratum conyzoides ).

[0042] Other materials: straw clippings and straw ash.

[0043] The implementation steps are as follows:

[0044] (1) First prepare the mixed matrix according to the weight ratio: 85% of straw clippings and 15% of straw ash.

[0045](2) Control experiment of Shenghongji: In March 2009, an experimental sample plot was selected from the abandoned farmland around the manganese mine, and various plants in the sample plot were eradicated to create planting holes. The direction of the rows is the same; the distance between two adjacent planting holes in the same row is 30 cm, and the distance between two adjacent plant rows is 30 cm. Fill each plant hole with 1.2 kg of mixed substrate. Matching planting: plant the two plants of green scallops and yellow vanilla osmanthus in the same row by interplanting, and insert the red thi...

Embodiment 3

[0050] Plant Material: Green Weed ( Celosia argentea ), Yellow Vanilla Osmanthus ( Melilotus officinalis ) and red thistle ( Ageratum conyzoides ).

[0051] Other materials: straw clippings and straw ash.

[0052] The implementation steps are as follows:

[0053] (1) First prepare the mixed matrix according to the weight ratio: 90% of straw clippings and 10% of straw ash.

[0054] (2) Control experiment of Shenghongji: In March 2009, an experimental sample plot was selected from the abandoned farmland around the manganese mine, and various plants in the sample plot were eradicated to create planting holes. The direction of the rows is the same; the distance between two adjacent planting holes in the same row is 30 cm, and the distance between two adjacent plant rows is 30 cm. Fill each plant hole with 1.5 kg of mixed substrate. Matching planting: plant the two plants of green scallops and yellow vanilla osmanthus in the same row by interplanting, and insert the red th...

Abstract

The invention relates to a method for preventing and controlling the invasion of exotic weeds Ageratum conyzoides. The materials used were Celosia argentea, Melilotus officinalis and Ageratum conyzoides, straw clippings and straw ash. Mix straw scraps and straw ash in proportion to make a mixed substrate, fill them in the planting holes created in the abandoned farmland, plant green stalks and yellow herb Osmanthus osmanthus in the same row by interplanting, and insert the red thistle into the two Between the plants, the interplanting is repeated in this way. The method is used to establish the dominant vegetation of green scallops and yellow herb sweetheart in a short period of time, and significantly inhibit the growth of thistle. The method has multiple advantages such as that the selected plants are all native species, the material is convenient to obtain, easy to grow, the time for rebuilding vegetation is short, the effect of preventing and controlling alien weeds is good, and there is no risk. The technology can be used for the ecological restoration of the land invaded by malignant alien weeds and the transformation of the ecosystem vulnerable to the threat of invasion.

Description

technical field [0001] The invention relates to an ecological prevention and control method for the invasion of foreign weeds, red thistle. Background technique [0002] There are more than 180 kinds of foreign plants in my country, among which there are more than 100 kinds of foreign weeds in 23 families, and more than 10 kinds have become vicious invasive weeds, such as solidago canadensis ( Sodidago canadensis ) and red thistle ( Ageratum conyzoides )wait. The invasion of alien plants will affect the cycle of soil organisms and nutrients, cause the loss of biodiversity, change the direction of community evolution, destroy the integrity and stability of the ecosystem, and cause huge economic losses. Alien plant invasion has become a global ecological and economic problem. [0003] my country attaches great importance to the problem of alien species invasion. In the relevant scientific and technological planning, the prevention and control of alien pests has been listed...
