Grotto top anti-seepage method based on cultivation of dominant species in local plant community

Abstract

The invention relates to a grotto top anti-seepage method based on cultivation of dominant species in local plant communities. The seepage prevention method comprises the following steps: (a) screening relative herbaceous dominant species with developed root systems and relatively high water absorption capacity in the same phenological period of plant communities at the top or the periphery of the grotto by adopting a nest type quadrat dominant species investigation method and a root system scanning method; (b) cultivating the seeds of the relative dominant herbaceous species, watering and weighing the seeds in the soil layer, recording the water absorption mass change in the growth process, and determining the final dominant herbaceous species; (c) arranging the final herb dominant species at the top of the grotto, arranging humidity sensors along the depth and length directions, recording the moisture content under different rainfall conditions, and determining the actual field water absorption and seepage prevention effects of the final herb dominant species; and (d) cultivating and planting the final herb dominant species at the top of the grotto according to the actual anti-seepage requirement and the water absorption and anti-seepage effect of the final herb dominant species to complete the anti-seepage treatment of the top of the grotto.
