Method for substituting for flaveria bidentis by utilizing grain amaranth

Abstract

The invention provides a method for substituting for flaveria bidentis by utilizing grain amaranth; in the method, the grain amaranth is adopted to carry out biological substitution to the flaveria bidentis; the method can lead the germination rate of the flaveria bidentis to be reduced by 80.43 percent, the average plant height is reduced by 77.30 percent, the average single plant branches are reduced by 98.96 percent, the average single plant leaves are reduced by 99.14 percent, the average single plant biomass liveweight is reduced by 92.54 percent, the average soluble protein content is reduced by 52.99 percent, and the method has remarkable control function to the foreign invasion of the flaveria bidentis; the grain amaranth is a common plant, the seed is easy to obtain, the plantingmethod is simple, and the operation is easy; the grain amaranth is pasture with good quality, while controlling the population quantity of the flaveria bidentis, the grain amaranth has a certain economical 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...

AI Technical Summary

Problems solved by technology

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 prevent and control chrysanthemum chrysanthemum is still in the experimental stage, and it has not been able to completely and effectively eradicate chrysanthemum chrysanthemum
