Abstract:

In order to research the dustfall adsorbing capacity in winter and its laws of 10 species of ornamental bamboo in Fuzhou were chosen to systematically study the dust accumulation on the leaves of different plants in time, height and direction three aspects by direct sampling and measurement, and statistical analysis as well. The results showed that: The dustfall adsorbing capacity of Sinobambusa tootsik, Bambusa eutuldoides var. basistriata, Thyrsostachys siamensis, Phyllostachys aurea, Phyllostachys heterocycla ‘Viridisulcata’, Phyllostachys propinqua; Bambusa tuldoides ‘Swolleninternode’ were higher than others, and Bambusa eutuldoides var. viridi-vittata showed a rising trend after the rain in the fourth day, Phyllostachys aurea, Phyllostachys heterocycla ‘Viridisulcata’, Bambusa vulgaris ‘Vittata’, and Bambusa eutuldoides var. basistriata have declined; Phyllostachys aurea, Sinobambusa tootsik, Phyllostachys heterocycla ‘Viridisulcata’, Bambusa vulgaris ‘Vittata’, Phyllostachys propinqua, Bambusa eutuldoides var. basistriata, Bambusa tuldoides ‘Swolleninternode’, in the distance the ground 150 cm unit leaf area dustfall adsorbing capacity more than 200 cm, especially Phyllostachys heterocycla ‘Viridisulcata’, Bambusa eutuldoides var. basistriata, Bambusa tuldoides ‘Swolleninternode’ have the significant differences, other was opposite, but the difference was not significant, and in the same height, The dustfall adsorbing capacity of Sinobambusa tootsik was the strongest, Bambusa vulgaris ‘Vittata’ was the worst; The dustfall adsorbing capacity was different in different directions in ten ornamental bamboos.
