摘要
以喜树半年生播种苗为试材,研究栽植密度和施肥配比、施肥量对叶片喜树碱含量的影响。结果表明:半年生喜树播种苗移栽密度以50株·m-2左右喜树碱含量最高。施用高氮肥料、高用肥量或加施B肥均导致叶片的喜树碱含量降低,以施用等比例NPK 26.7 g·m-2喜树碱含量最高。
C.acuminata′s half year old seedlings were used as test subjects.We studied the effects of planting density and fertilizer ratio on the leaves camptothecin content.Camptothecin content in the leaf was reduced by application B ,high nitrogen fertilizer and high amount of fertilizer.The highest Camptothecin content in the leaves of C.acuminata was got from half year old seedlings with the treatment of NPK 26.7 g· m-2.
