Method for substituting and controlling flaveria bidentis by utilizing amorpha fruticosa

Abstract

The invention provides a method for substituting flaveria bidentis by utilizing amorpha fruticosa. In the method, the amorpha fruticosa is adopted to biologically substitute the flaveria bidentis. In the method, the plant height, the branch number, the living weight per plant, the plant number per square meter and the soluble protein content of the flaveria bidentis are significantly decreased comparatively; the method can play the role in obviously controlling alien invasion of the flaveria bidentis; especially for the second year, the inhibitory action of the amorpha fruticosa to the flaveria bidentis is more obvious; in addition, the flaveria bidentis also has the functions of improving the soil, conserving the water resource, conserving the water and soil, beautifying the environment, and providing the feeds, the nectar sources and the weaving materials and the like, thus the method provided by the invention can control the population quantity of the flaveria bidentis, and also can realize better economic value.

Description

technical field [0001] The invention relates to the technical field of ecological control, in particular to a biological substitution method of chrysanthemum chrysanthemum. Background technique [0002] Organisms invade another new environment from the original living place through natural or man-made ways, causing economic losses or ecological disasters to the biodiversity, agriculture, forestry, animal husbandry and fishery production and human health in the invaded place (Wan Fanghao, Guo Jianying, Wang Dehui . Hazards and management strategies of alien invasive organisms in China [J]. Biodiversity, 2002, 10(1): 119-125.), that is, biological invasion. In nature, biological invasion is a ubiquitous phenomenon, and the types of biological invasion include almost all biological groups. With the integration of the global economy, international and domestic trade exchanges are becoming more and more frequent, and the probability of successful biological invasion is also incre...

But chemical control is ineffective against seeds in soil, fails to eradicate chrysanthemum, and poses too many threats to human health and non-target species

In addition, with the extensive use of chemical agents, the resistance of chrysanthemum will continue to increase. The high price of agents and the necessity of repeated application often make continuous application control impossible.

[0012] Biological control: the use of natural enemies or pathogenic microorganisms to control chrysanthemum is still in the experimental stage, and it has not been able to completely and effectively eradicate chrysanthemum, and the plants available for controlling chrysanthemum are very limited, and most of them are annual herbaceous plants. The period is short, the growth is unstable, and it is easy to be destroyed, so it cannot achieve the effect of controlling chrysanthemum for many years; and the types and numbers of such plants are very limited, so that it is impossible to fully utilize other beneficial effects of the plant according to specific needs while controlling chrysanthemum
