Method of using native plants to control growth of exotic ageratum conyzoides

Abstract

The invention discloses a method of using native plants to control growth of exotic ageratum conyzoides, which includes: selecting sample plots from abandoned lands suitable for growth of ageratum conyzoides, eradicating various plants in the sample plots, digging planting pits, mixedly planting xanthiumsibiricum, amaranthus paniculatus, polygonum orientale and chenopodium album into the plantingpits, interplanting the ageratum conyzoides among the former plants, and performing the cycle for interplanting. The xanthiumsibiricum, the amaranthus paniculatus, the polygonum orientale and the chenopodium album are all resistant to allopathic stress from the ageratum conyzoides, and can be mixedly planted to inhibit growth of the ageratum conyzoides and resist its invasion. The method has the advantages that the plants used in the method are all native and easy to propagate and grow fast, revegetation is short, exotic weed control is effective, management is easy, no ecological risks occurand the like.

Description

technical field

[0001] The invention relates to a method for preventing and controlling the invasion of foreign weeds, red thistle. Background technique

[0002] Alien plant invasion has become a global ecological and economic problem. Red Thistle ( Ageratum conyzoides ), also known as ageratum, blue emerald ball, etc., is a plant of the genus ageratum in the family Asteraceae. Thistle originated in South America and was introduced into my country through artificial introduction. It has a large amount of occurrence and serious damage. It is a regional malignant weed. It breeds and spreads in a large number of cultivated land, affecting the growth and development of crops, resulting in reduced production. Thistle is a weed that can produce and release a variety of allelochemicals, and has a heterogeneous effect. Because of its wide ecological adaptability, it often forms single-optimal or co-optimal communities in the invaded areas, inhibiting the growth of other plants,...
