摘　　要：以南方红豆杉2年生苗为材料,采用完全随机区组试验设计,在福建明溪对南方红豆杉盆栽苗开展了施肥试验,研究施肥对南方红豆杉盆栽苗观赏美感的影响。结果表明,施肥对南方红豆杉观赏盆栽苗的当年新枝数量、当年萌发叶片生物量鲜重以及叶片色泽等性状与叶绿素、脯氨酸、可溶性糖、丙二醛含量等生理指标有着显著性影响。施肥提高了南方红豆杉当年侧枝数量、叶片色泽美感、叶绿素含量;当年萌发叶片生物量鲜重随施肥量增加先升后降;脯氨酸、丙二醛含量随施肥量增加而升高;可溶性糖含量随施肥量增加先升后降。The fertilization experiments with RCB design were constructed in fujian province mingxi county by u- sing potted Taxus chinensis var. mairei with 2-year-old seedlings as material, and the results showed that the effects of fertilizer on the growth of annual branch number, the annual leaves＇ fresh biomass, leaves colors and chloro- phyll, proline, soluble sugar, and MDA were significant. The growth of annual branches number, leaves colors and chlorophyll content in the potted seedlings were accelerated distinctly by fertilization, the annual leaves fresh biomass increased at the beginning and then decreased with the fertilizer amount increasing. Proline, MDA content increased with the fertilizer amount increasing. The soluble sugar content increased at the beginning and then de- creased with the fertilizer amount increasing.
