摘要
研究了4种栽培基质以及添加基肥处理对槲蕨小苗生长发育的影响。结果表明:处理1的草炭土:素沙=1:1基质中的小苗植株生长发育最快,叶片颜色浓绿,干质量最大;添加基肥有利于槲蕨小苗的生长发育,根系比不添加基肥的发达。草炭土:素沙=1:1的栽培基质添加基肥是槲蕨小苗生长发育的理想基质。
The fern Drynaria roosii were cultured on four kinds of mediums (turf soil: sand = 1:1, turf soil:loam:sand = 1 : 1 : 1, loam: sand = 1 : 1 and vermiculite: sand =1 : 1 ) added with or without basal fertilizer to observe the growth and development of D. roosii seedlings. The seedlings grew the fastest with dark green leaves and the highest fresh leaf weight when cultured on the medium turf soil + sand. The medium added with basal fertilizer improved the growth and development of the seedlings, with their root system being better than those cultured without additional basal fertilizer. The medium turf soil + sand ( 1 : 1 ) + basal fertilizer is hence optimal for D. roosii seedlings to grow.
