摘　　要：本试验选用‘旭港’、‘二乔’、‘贵妃插翠’、‘彤云’、‘花王’5个牡丹品种,晾根9天后进入温室大棚进行促成栽培,通过观察催花过程中各牡丹品种的发芽与抽枝情况,测定、记录相关数据,结果表明,不同牡丹品种新枝每5天的生长量差异较大,分布在0.020~4.714 cm之间,但抽枝规律基本相同,均呈现较为平稳上升的生长趋势;花蕾横径每5天生长量差异较小,分布在0.082~0.742 cm之间;不同品种成花率差别大,开花特性对促成栽培影响较为明显,晚花品种与早花品种不宜在同一温室环境中进行促成栽培.In this test,five tree peony varieties(Xugang,Erqiao,Guifeichacui,Tongyun and Huawang)are planted in the greenhouse after 9 days of roots air drying,the germination and branching of each peony variety are observed in the process of flowering,and the relevant data are measured and recorded.The results show that the growth of new branches of different tree peony varieties varies greatly every five days,distributed in the range of 0.020-4.714cm,but the branching law is basically the same,showing a relatively stable upward growth trend;the transverse diameter of flower buds per 5-day length difference is small,distributed between 0.082-0.742cm;the flowering rate of different varieties has great difference,and the flowering characteristics has obvious influence on forcing cultivation.It is not suitable to promote cultivation in the same greenhouse environment.
