Artificial purification and rejuvenation planting method for introduction of angustifoliate Stachys baicalensis Tisch ex Benth

Abstract

The invention discloses an artificial purification and rejuvenation planting method for introduction of angustifoliate Stachys baicalensis Tisch ex Benth. Through identification of different varieties in the wild, the angustifoliate Stachys baicalensis Tisch ex Benth having a good phenotype and meeting the requirements of nectariferous plants are introduced and cultivated, and purification and rejuvenation are conducted in a nursery field by means of a special planting method; through phenotypic selection (such as large stem diameter, firmness and uprightness, lodging resistance and the like), seeds of good plants are picked, and seeds which meet demands after secondary selection are stored for reproduction, so that seed sources are provided for large-scale artificial planting of the angustifoliate Stachys baicalensis Tisch ex Benth. Not only is the endangered species, the angustifoliate Stachys baicalensis Tisch ex Benth saved, but more importantly, the optimal species of ecological and economical double orientation and co-fusion is provided for the national restoration project of the three river wetland reserve through artificial reproduction.

Description

Problems solved by technology

Beginning in the 1950s, the large-scale development and construction of the frontier, enclosing and reclamation, intercepting and changing river courses, blindly developing wetlands, etc., led to a sharp reduction in the area of ​​wetlands in this area, and the integrity of the whole was destroyed. At the same time, a large amount of surrounding farmland was used. Chemical fertilizers and toxic pesticides that are difficult to decompose in a short period of time enter the river with surface runoff during the rainy season, polluting the entire wetland waters and posing a fatal threat to the organisms living in the area
