【摘要】 在太湖滩地采用水杨梅、光蜡树、水杉、池杉和柳树(对照)进行耐水性比较试验,结果表明:(1)在淹水深度10.0～30.0 cm、连续淹水时间40 d,水杨梅和柳树(对照)的成活率分别为100%和99.5%,光蜡树、水杉和池杉的成活率分别为19.5%,30.2%和31.1%。(2)水杨梅的耐淹水能力略高于柳树(对照),水杨梅的生长势和生长量一切正常,且叶色翠绿。更多还原

【Abstract】 In this paper,the silvicultural results on Taihu beach of A.rubella Hance,Fraxinus griffithii Clarke,Metasequoia glyptostroboides Hu et Cheng,Taxodium ascendens.Brongn,and Salix babylonica control,through the different species in different regions,different flooding duration and different flooding depth of water was compared.In the flooded depth of 20-60.5 cm,through continuous observation of flooding up to 40d,we found: 1) The survival rates of A.rubella and control willows were100% and 99.5%,and those of F.griffithii,M.glyptostroboides and T.ascendens were 19.5%,30.2% and 31.1%,respectively.2) In the fourth time in the lake beach area,the resistance ability to flooding of A.rubella was a little higher than that of willows.Both of the growth potential and amount of A.rubella were all normal,and it had good emerald green leaves which was evergreen species and has less pests and diseases.According to the greening,beautification and landscaping considerations,lake beaches slash pine can be selected as an excellent evergreen species for wetland plantation,especially for freshwater wetland vegetationrestoration and reconstruction in China’s Taihu Lake area.更多还原
