[0023] Example 4. Ecosystem Management Techniques

[0024] For the single-species substitution of Sorbus dansana, within one month after sowing, due to its weak growth in the early stage, attention should be paid to maintaining proper soil moisture, and frequent removal of other plants to prevent the The growth of weeds has adverse effects on the later growth of Sorbus dansana, and when the height of Sordansis sagodansus reaches 30 cm, it can begin to exert the advantage of occupying the space ecological niche and inhibit the growth and re-invasion of Sorbus chrysanthemum. For the replacement of the mixed species of Sorghum grass and Dactylis chinensis, because the ground cover can be realized earlier to inhibit the weeds, generally 1 to 2 times of weeding is enough.

[0025] In addition, human activities unrelated to ecosystem management, especially grazing, are always strictly prohibited in all alternatively managed sites, as livestock feeding and trampling will adversely af...

Abstract

The invention discloses a method for controlling invasion of flaveria bidentis through ecological substitution. The method comprises the following steps: taking sorghum sudanese or sorghum sudanese and cocksfoot as the plant for controlling the invasion of the flaveria bidentis; and planting the sorghum sudanese or planting the sorghum sudanese and the cocksfoot in a hybrid way in an ecosystem which may be invaded easily by the flaveria bidentis so as to control the invasion of the flaveria bidentis. The sorghum sudanese is a species which can contend against the flaveria bidentis in a dry season and enjoy apparent advantage in the struggle for survival with the seedling of the flaveria bidentis. The sorghum sudanese can completely play a role in the ecosystem which can be easily invaded or has been invaded by the flaveria bidentis through introduction, planting, rational configuration and scientific management, so that the seedling of the flaveria bidentis can be effectively prevented from growing quickly in the dry season and occupying the space by using the effect of time difference; and consequently, the method provides basic protection to prevent the invasion of alien invasive species flaveria bidentis as an alternative and to perform sustainable management.

Description

technical field [0001] The invention relates to a method for preventing and containing chrysanthemum from invading the ecosystem. Background technique [0002] Invasive alien species (IAS) refers to the introduction from the natural distribution area through intentional or unintentional human activities, forming self-regeneration ability in the local natural or semi-natural ecosystem, and giving the local ecosystem or landscape Species causing significant damage or impact. Because of their great threats to human health, ecological functions of natural ecosystems, biodiversity, and agricultural and animal husbandry benefits, invasive alien organisms have become a hot issue in global biosecurity, environment, and economy, and have attracted great attention from all countries in the world. Invasive plants, an important part of invasive organisms, have become economic problems and threaten natural ecosystems because the destruction of plant communities can lead to the disintegr...
