| The paper focuses on the subject of plain river networks,Arbor Species and shrub tree species resources which were suitable for bank protection planting of plant varieties were investigated and screening in Jiaxing and surrounding areas.The plant tree varieties which were suitable for local ecological slope protection can be used to explore the commercialization production mode for popularization and application at the same time.It has important theoretical significance and practical value and will be provide a solid theoretical foundation and practical reference for the practice of ecological river course construction in Jiaxing.The results of the research and development show as fowllos:(1).According to the investigation and selection,more than 5 Arbor tree and 20 shrub tree water tolerant species resources were founded.Arbor tree Species were Photinia xfraseri,Ligustrum ovalisolium,Photinia xfraseri,Ligustrum ovalisolium,Viburnum japonicum,Buxus sinica,and Chaenomeles speciose.20 shrub tree species were Nyssa aquatic,Taxodium mucronatum × Cryptomeria fortune,Quercus palustris,Salix rosthornii,Taxodium ascendens,Taxodium distichum,Taxodium mucronatum,Salix babylonica,Metasequoia glyptostroboides,Taxodium hybrid 'zhongshanshan',Camptotheca acuminate,Broussonetia papyrifera,Pterocarya stenoptera,Ulmus parvifolia,Acer negundo,Pinus elliottii,Ligustrum compactum,Bischofia polycarpa,Sapium sebiferum,Michelia chapensis and so on.(2).One water tolerant woody plant germplasm nursery and four rare and precious local tree species germplasm breeding base were setted up.And we also Established an area of 430 mu of Seedling propagation as the base,Cultivating seedlings 28 strains.(3).We also developed 20 kinds of typical plant configuration mode for the river greenization,road greenization and village greenization,and meanwhile area of 1600 mu for fundamental key with native tree species of afforestation demonstration were setted up. |
