【摘要】 通过对省沽油科圆齿野鸦椿、壳斗科8种、木兰科2种、冬青科2种、山茶科4种、蔷微科2种、桃金娘科的赤楠、八角科的莽草、槭树科的五裂槭、交让木科1种、金缕梅科3种等26种亚热带乡土树种的种子预处理、种子主要播种品质参数测定、对苗木的苗高、地径、主根长、大于5cmI级侧根数、根幅、冠幅、鲜叶重、鲜干枝重、鲜根重的测定,以及对苗木物候、苗木生长节律进行研究,从而得出上述树种的较为系统的育苗技术。更多还原

【Abstract】 Twenty-six native tree species of subtropical region such as Euscaphis konishii Hayata,Manglietia moto Dandy,Ilex szechwanensis Loes,Tutcheria microcarpa Dunn,Ternstroemia kwangtungensis Merr,Photinia glabra(Thunb.) Maxim.,Syzygium buxifolium Hook.et Arn,Illicium lanceolatum A.C.Smith,Cyclobalanopsis jenseniana Chenget Houg,Acer oliverianum Pax,Daphniphyllum macropodum Miq,Altingia chinensis(Champ.)Oliv.ex Hance and others are studied,which refers to their seeds’preprocessing,parametric determination of sowing factors and their seedlings’height,ground diameter,root length,number of I lateral roots longer than 5cm,root span,crown span,weight of fresh leaves,brunches and roots,periodic biological phenomena and growth rhythm.In this way,the seedling-raising techniques on above species are obtained.更多还原
