摘要: 为探究花生壳是否可以替代树皮作为大花蕙兰世界和平Cymbidium hybridumShijieheping的栽培基质及其最佳体积配比，将6个月苗龄的大花蕙兰世界和平组培苗栽植于纯树皮（ck1），体积分数为80%树皮+20%花生壳（B1），50%树皮+50%花生壳（B2），45%树皮+45%花生壳+10%草炭（B3），20%树皮+80%花生壳（B4），15%树皮+75%花生壳+10%草炭（B5），纯花生壳基质（ck2）以及80%树皮+10%草炭+10%植金石（M1），40%树皮+40%花生壳+10%草炭+10%植金石（M2）和80%花生壳+10%草炭+10%植金石（M3）共10类基质中，通过每月测定其生长生理指标探究适宜大花蕙兰世界和平生长的最佳基质配比。结果显示：M3与M2 处理的植株生长量、净光合速率、蒸腾速率、暗呼吸速率及成活率显著优于其他处理，表明花生壳可以部分或全部替代树皮，添加草炭、植金石效果最佳；（50%~80%）的花生壳+（0~10%）草炭+10%植金石+（0~30%）树皮是北方地区栽培大花蕙兰世界和平的理想基质配比。图5表4参14Abstract: To choose suitable substitute-media of tree bark for Cymbidium hybridum Shijieheping, six-month-old seedlings were planted with the same cultural practices for 10 months in 10 media: ck1 （pine tree bark）, B1 （80% （v/v） tree bark + 20% peanut hulls）, B2 （50% tree bark + 50% peanut hulls）, B3 （45% tree bark + 45% peanut hulls + 10% peat）, B4 （20% tree bark + 80% peanut hulls）, B5 （15% tree bark + 75% peanut hulls + 10% peat）, ck2 （peanut hulls）, M1 （80% bark + 10% peat + 10% cymbidium stones）, M2 （40% peanut hulls + 40% bark + 10% peat + 10% cymbidium stones） and M3 （80% peanut hulls + 10% peat + 10% cymbidium stones）. Results indicated that compared with other groups, seedings planted in both M3 and M2 developed significantly in growth indexes, photosynthetic rate, transpiration rate, dark respiratory rate, and survival rate. Thus, for industrial production of C. hybridum Shijieheping in northern China, peanut hulls with addition of cymbidium stones and peat could be used as an ideal culture media to replace tree bark. ［Ch, 5 fig. 4 tab. 14 ref.］
