Method for preventing and controlling invasive weed solidago canadensis by using locusta chinensis

Abstract

The invention belongs to the technical field of biological invasion worst weed treatment, and particularly relates to a method for preventing and controlling invasion weed solidago canadensis by locusta chinensis. The method comprises a preparation step of locusta chinensis, a release method and a region immobilization method. The implementation process comprises the steps of light source supplementing, insect throwing in the seedling stage, light source adjusting and insect re-throwing in the growing stage, specifically, in a solidago canadensis invasion area, an artificial light supplementing mode is adopted, and then locusta sinensis is thrown, so that leaves of solidago canadensis are fed, photosynthesis is difficult to conduct, seedlings die or flower seeds are difficult to form, and the purpose of preventing and treating the locusta sinensis is achieved. Intrusion diffusion is controlled, so that the ecological function is restored. The method is simple, high in operability and small in regional ecology interference, the natural enemy prevention and control principle is fully utilized, diffusion and propagation of solidago canadensis can be effectively controlled, the released locusta sinensis can be prevented from being abused to cause disasters, and ecological balance is maintained.

Description

technical field [0001] The invention belongs to the technical field of biologically invasive malignant weed control, and in particular relates to a method for controlling the invasive weed Solidago canadensis by using the Chinese sword horned locust. Background technique [0002] Solidago canadensis L. is a vicious invasive weed that poses a serious threat and harm to the regional ecological environment, agricultural production, and human health in my country. It was introduced into Shanghai as an ornamental plant in my country in 1935. Due to the lack of natural enemies and strong reproductive and spreading capabilities, it quickly spread to eastern coastal areas such as Jiangsu, Zhejiang, and Shandong, and continued to spread inland, making it difficult to contain. Mu, the study found that the root allelopathic extract of Solidago canadensis can inhibit the germination rate of wheat by more than 50%. In view of the characteristics of solidago canadensis, such as serious dam...
