落羽杉属(Taxodium Rich)包括三个种:落羽杉(T.distichum Rich)、池杉(T.ascendens Brongn)和墨西哥落羽杉(T.Mucronatum Ten)。它们具有干直、树形美观、生长快、耐旱耐湿耐瘠、抗风、抗病虫等特点,是园林绿化、湖网地区造林的速生优良树种。为了加速落羽杉属优树的繁殖,实现良种化,为建立种子园提供苗木,我所于1975年进行了落羽杉属优树嫁接繁殖试验。共嫁接池杉优树2560株,成活2359株,成活率90％;落 Taxodium Rich is composed of three species: T.distichum Rich, T. ascendens Brongn, and T. mucronatum Ten. They are dry and straight, beautiful tree, fast growth, drought and drought resistance barren, wind, pests and diseases and other characteristics, is landscaping, afforestation Lake area fast growing good tree species. In order to speed up the propagation of the genus Taxodium, to achieve the variety, to establish seed orchard to provide seedlings, I conducted in 1975, Taxodium sylbrique tree graft reproduction. A total of 2560 cedar trees were grafted, 2359 surviving, the survival rate of 90%;
