Embodiment

[0019] A method for comprehensive prevention and control of alien species Echinochloa chinensis, the method is specifically to construct large-scale emergent plants in wetland coastal swamp areas with a water depth of less than 30 cm in the invasion area of ​​the alien species Echinochloa chinensis, and according to the The water-flooding conditions for the growth of aquatic plants are planted in the wetland where Asteroides spinosa grows. Emergent plants choose grass, reeds, wild rice and lotus with water-flooding conditions of 0-220cm. The specific construction methods are as follows:

[0020] S1: Construct the plant community in the shallow water area: choose reeds to plant on the edge of the invasion area of ​​the alien species Echinochloa sinensis in the coastal swamp area of ​​the wetland;

[0021] S2: Construct the plant community in the deep water area: the wild mushroom community was selected to be planted on the edge of the invasive species in the center of the coasta...

Abstract

The invention discloses a method for comprehensively preventing and controlling alien species alternanthera philoxeroides, which specifically comprises the following steps of: constructing large emergent aquatic plants in a wetland bank zone marsh area in which the coverage of an alien species alternanthera philoxeroides invasion area is more than 70% and the water depth is less than 30cm; according to the method, alligator alternanthera is planted in a wetland where the alligator alternanthera grows according to the flooding condition of emergent aquatic plant growth, the emergent aquatic plants are selected from silvergrass, reed, wild rice and lotus with the flooding condition that the water depth is 0-220 cm, the photosynthesis of alien species alligator alternanthera is inhibited through indigenous planting of large emergent aquatic plants including silvergrass, reed, wild rice and lotus, the growth of alien species alligator alternanthera is inhibited, and the growth of the alien species alligator alternanthera is inhibited. The utilization of soil nutrient resources and water resources is reduced, so that the aim of controlling alien species Alternanthera philoxeroides is gradually achieved.

Description

technical field [0001] The invention relates to the technical field of ecological environment, in particular to a method for comprehensively preventing and controlling the foreign species Asteroides colloides. Background technique [0002] At present, the alien species Echinochloa sinensis invades frequently in the wet areas of the middle and lower reaches of the Yangtze River, causing rampant damage, seriously affecting the biodiversity of wetlands, and even affecting flood regulation and water storage, water purification, and shipping. Therefore, aiming at this ecological environment problem, the present invention proposes a method for comprehensively preventing and controlling the alien species Echinochloa chinensis. Contents of the invention [0003] The present invention proposes a method for the control and prevention of the alien species of Alpinia sinensis, aiming at the wetland coastal swamp area where the coverage of the invasion area of ​​the alien species is mo...
