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

Embodiment 1

[0041] On April 18th, in the place where Chrysanthemum chrysanthemum occurred, perennial ryegrass was planted by drill with a row spacing of 20cm, and sunflowers were planted between rows of perennial ryegrass by on-demand sowing with a plant spacing of 30cm. The sowing depth of perennial ryegrass is 1cm, the sowing depth of sunflower is 5cm; the planting density of perennial ryegrass is 1g / m 2 , the planting density of sunflowers is 2 trees / m 2 . Perennial ryegrass and sunflower were managed using conventional field methods. When chrysanthemum blooms, the following data are measured, and the emergence rate of chrysanthemum is 52.9%, the average plant height is 72.82cm, the average number of branches per plant is 17.7, the average number of leaves per plant is 120, and the average biomass per plant is 13.37g, and the average soluble protein content is 0.45mg·g -1 FW, the average protective enzyme content was 10.06ΔA470 min -1 g -1 FW.

Embodiment 2～12

[0043] Except for the contents listed in Table 1, Examples 2-12 were implemented in the same manner as Example 1.

Abstract

The invention provides a method for substituting for flaveria bidentis by utilizing combination of sunflower and perennial ryegrass; in the method, the combination of the sunflower and the perennial ryegrass is adopted to biologically substitute for the flaveria bidentis; the germination rate of the flaveria bidentis can be reduced by 51.52 percent, the plant height can be reduced by 77.71 percent, the branching quantity of the single plant is reduced by 98.23 percent averagely, the leaf quantity of the single plant is reduced by 97.57 percent averagely, the biomass liveweight of the single plant is reduced by 97.87percent averagely, and the average soluble protein content is reduced by 73.5 percent, and the method has remarkable control function to external invasion of the flaveria bidentis; the seeds of the perennial ryegrass and the sunflower are obtained easily, and the planting method is simple and is easy to operate; in addition, the perennial ryegrass is a good pasture, the sunflower is an important oil crop; by adopting method, while controlling the quantity of the flaveria bidentis, a certain of economic value can be realized.

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...
