摘要
为筛选出适宜大花蕙兰生长的代用基质,将2年生的大花蕙兰中苗种植于树皮(CK)、玉米芯、花生壳、树皮+玉米芯(1∶1)、树皮+花生壳(1∶1)这5种基质中,测定其叶长、叶宽、叶面积、叶绿素含量、可溶性糖含量以及SOD酶活性。结果表明:50%树皮+50%花生壳为基质栽培的大花蕙兰植株生长与对照组最为接近,花生壳可以作为树皮代用基质进行产业化生产。
In order to choose suitable substitute-media for hybrid cymbidium, two-year-old hybrid cymbidium was planted in pine tree bark （CK）, corncob, peanut hulls, pine tree bark ＋ corncob （1：1） and pine tree bark ＋ peanut hulls （1 ：1）, respectively, and then the length, width and area of leaf, the contents of chlorophyll and soluble sugar and the activity of SOD in leaf were determined. The results indicated that the growth of hybrid cymbidium planted in pine tree bark ＋ peanut hulls （1：1） was the most similar to that in control group. Therefore, the peanut hulls can be used as culture media to replace tree bark for industrial production.
