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 is still in the experimental stage, and it has not been able to completely and effectively eradicate chrysanthemum. At present, most of the plants that can be used to control chrysanthemum are annual herbaceous plants with a short growth period and short growth period. Unstable, easy to be destroyed, and can not achieve the effect of controlling chrysanthemum for many years; and the types and numbers of the plants available for selection are very limited, making it impossible to fully utilize other beneficial effects of the plant according to specific needs while controlling chrysanthemum

Embodiment 1

[0038] On April 18, 2009, Satawang was sown by drill. See Table 1 for the row spacing, sowing density and sowing depth of Satawang. Then sow chrysanthemum chrysanthemum, the sowing density of chrysanthemum chrysanthemum is 0.05g / m 2 , the sowing depth is about 0.5cm, and it is sown again in the same way in the second year at the same time. The cell size is 3×3m 2 . Use conventional field methods to maintain and manage Satawang.

[0039] In the 1st and 2nd year after sowing of the comparative example (see the comparative example below), about 50% of the plants of the yellow top chrysanthemum in the plot flowered (actual measurement time: the first year was August 21, and the second year was August 23. ) to measure the following indexes: plant height, number of primary branches, number of secondary branches, biomass, number of plants per square meter of Chrysanthemum chrysanthemum, soluble protein content and protective enzyme content. The results are shown in Table 2 and T...

Embodiment 2～15

[0041] Except for the contents listed in Table 1, Examples 2-12 were implemented in the same manner as Example 1. The results of the measurement indicators are shown in Table 2 and Table 3.

Abstract

The invention provides a method for replacing flaveria bidentis (L.) kuntze by astragalus adsurgens. In the method, flaveria bidentis (L.) kuntze is biologically replaced by astragalus adsurgens. In the method, the adopted astragalus adsurgens grows quickly after recovery from transplanting and can quickly cover the ground surface, so that the emergence of seedlings of flaveria bidentis (L.) kuntze is suppressed; and flaveria bidentis (L.) kuntze is shaded by using a strong density effect at the late stage, so that the growth of flaveria bidentis (L.) kuntze is suppressed. Moreover, astragalus adsurgens is excellent pasture for improving mountain wastes and fixing the sand, and can be taken as a green manure, so that a good economic value can be realized and / or environmental effect is improved while the population of flaveria bidentis (L.) kuntze is controlled.

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...
