裸果木(Gymnocarposprzewalskii)为国家二级珍稀濒危保护植物。迄今,关于裸果木人工栽培特别是无性繁殖方面的研究,工作不多,成效甚微。笔者近三年调查了裸果木的生境,研究了其繁殖栽培技术,取得了一定成果。结果表明:裸果木的物候期比原产地稍早,生长发育较好,能正常开花结果;种子质地松软,无需特殊处理,在沙壤土播深2cm,10天许发芽出土并且出苗较为整齐;插播育苗选1-2年生枝条,用100、150mg/L ABT一号生根粉药液浓度处理其插条,均能达到40-80%的成活率。
Gymnocarpos przewalskii is a national grade II rare and endangered plant. So far, little research has been done on artificial cultivation of bare fruit, especially asexual reproduction, with little success. In recent three years, the author investigated the habitat of bare fruit trees, studied its propagation and cultivation techniques, and achieved certain results. The results showed that: the bare fruit of the phenology earlier than the origin, good growth and development, can flowering results; seed texture is soft, without special treatment, sandy loam sowing depth 2cm, 10 days germination and germination unearthed more neat; Select 1-2 years old branches, with 100,150 mg / L ABT rooting powder liquid concentration of its cuttings, can reach 40-80% survival rate.
