摘　　要：通过系统的试验观测,研究了3种不同的整枝方式对一品红千禧(Euphorbia pulcherrimaW illd.‘M illen ium’)外观品质的影响。结果表明:在秋冬季光温较低的条件下生产一品红时,开花时的株高、冠幅、冠高比等指标4侧枝处理要显著优于3、5侧枝处理;植株丰满度、总叶面积指数、苞叶面积指数等指标4、5侧枝处理植株没有差异,但均优于3侧枝处理;在花蕾出现以后的整个生长时期4侧枝处理的植株总体外观品质均优于3、5侧枝处理植株。The effect of 3 different pruning methods （ keep 3, 4 and 5 branches per plant, respectively） on quality of poinsettia （Euphorbia pulcherrima Willd. ＇ Millenium＇ ） were investigated. The results showed that plants with 4 branches had the best plant height, canopy diameter and the ratio of canopy diameter to plant height; the plant chubbiness index, total plant leaf area index and bract area index with 4 and 5 branches were similar, but higher than those of plants with 3 branches; the whole plant external quality of the plants with 4 branches was significantly better than that of plants with 3 and 5 branches during the whole growing period from bud appearance to harvest.
