7—8月份,月季生长旺期,选健壮枝从枝条顶部以下30—40厘米处、在叶柄下,半厘米地方环割,剥去一圈树皮。经过处理的枝条,由于韧皮部筛管被破坏,上部叶子制造的养料不能向下输导,就积存在切断地方,形成瘤状愈伤组织。9月中旬以后,从愈伤组织下边把枝条剪下,将剪下的枝条插入水中,几小时后就可插入 7-8 months, the growing season of roses, choose robust branches from branches below 30-40 cm at the petiole, half a centimeter around the ring cut, stripped of a circle of bark. After treatment of the branches, due to the phloem sieve is destroyed, the upper leaf nourishment can not be produced down the guide, the accumulation in the cutting place, the formation of tumorous callus. After mid-September, the branches are cut off from the underside of the calluses, and the cut branches are inserted into the water and can be inserted after a few hours
