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

Embodiment 1

[0057] On April 18th, in the place where the yellow top chrysanthemum occurred, alfalfa was planted by drill, with a planting row spacing of 30cm, a planting depth of 1cm, and a planting density of 1g / m 2 , using conventional field methods to maintain and manage alfalfa. When chrysanthemum blooms, the following data are measured, and the emergence rate of chrysanthemum is 25%, the average plant height is 98cm, the average number of branches per plant is 63, the average number of leaves per plant is 200, and the average biomass per plant is 330g, the average soluble protein content is 0.8mg·g -1 FW, the average protective enzyme content was 8.9ΔA470 min -1 g -1 FW.

Embodiment 2～12

[0059] Except for the contents listed in Table 1, Examples 2-12 were implemented in the same manner as Example 1.

Embodiment 13

[0061] On April 18th, in the place where the chrysanthemum occurred, sunflowers were planted on demand, with a planting row spacing of 30cm, a plant spacing of 30cm, a planting depth of 5cm, and a planting density of 2 trees / m 2 , using conventional field methods for conservation and management of sunflowers. When chrysanthemum blooms, the following data are measured, and the emergence rate of chrysanthemum is 55%, the average plant height is 105.5cm, the average number of branches per plant is 35, the average number of leaves per plant is 150, and the average biomass per plant is 44.6g, and the average soluble protein content is 0.89mg·g -1 FW, the average protective enzyme content was 13.2ΔA470 min -1 g -1 FW.

Abstract

The invention provides a method for replacing flaveria bidentis by utilizing combination of a sunflower and an alfalfa. In the method, the alfalfa and / or the sunflower is adopted to carry out biological substitution on the flaveria bidentis. The method lowers the emergence rate and the plant height of the flaveria bidentis, reduces the branch number, the leaf number, the biomass and the content of soluble protein of the flaveria bidentis and can fulfill the obvious control function on external invasion of the flaveria bidentis. Seeds of the alfalfa and the sunflower are also easily obtained, and therefore, the planting method is simple and is easy to operate. In addition, the alfalfa is a kind of herbage with high quality, and the sunflower is a kind of important oil crop. The flaveria bidentis population quantity can be controlled and a certain economic value can also be realized by adopting the method.

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...
