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

Embodiment 1
[0040] Except for the contents listed in Table 1, Examples 2-12 were implemented in the same manner as Example 1.
Embodiment 2～12
[0042] Do not sow seed amaranth in the place where chrysanthemum chrysanthemum takes place, and measure the following data when chrysanthemum chrysanthemum blooms, and draw the emergence rate of chrysanthemum chrysanthemum to be 92%, the average plant height to be 185cm, the average number of branches per plant to be 575, and the average number of leaves per plant to be 1850 tablets, the average biomass per plant is 335g, and the average soluble protein content is 1.17mg·g -1 FW, the average protective enzyme content was 11.5ΔA470 min -1 g -1 FW.

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...
