荷泽牡丹引种栽培研究Ⅱ.生物学特性及物候期

为丰富湖南地区的牡丹品种及其花色，对荷泽地区的15个牡丹品种进行了引种，并进行了大棚避雨栽培试验．结果表明，牡丹枝条的年生长量为16．70-23．20cm，叶长为8.30～18．90cm，叶宽为3．80～11．20cm，花径为739～13.42cm．牡丹在长沙的生长情况为：1月上旬(01-01-01-05)是萌芽期，3月上中旬(03-04-03-20)是枝条的旺盛生长期；2月上旬(02-01-02-10)花蕾初现，3月中旬(03-15-03-25)花蕾现色，3月下旬到4月上旬(03-25-04-10)为开花期；11月上旬(11-05-11-10)进入落叶休眠．试验表明，利用大棚避雨栽培，荷泽牡丹可以在高温高湿的长沙地区正常生长，具有较高的观赏价值，值得推广栽培．

Study on Introduction and Cultivation of Heze PeonyⅡ.Biological Character and Phonological Time

To enrich the varieties of peony in Hunan,15 varieties of Heze peony are introduced into Changsha area.The results show:the growing length of stem is 16.70~23.20 cm;the length of leaf is 8.30~18.90 cm;the width of leaf is 3.80~11.20 cm;the diameter of flower is 7.39~13.42 cm.01-01~01-05 is the time of sprouting bud;the growing speed of branch is very fast,during the time of 03-04~03-20;the flower buds show in 02-01~02-10;03-15~03-25 is the time showing bud color;the blooming date is 03-25~04-10.The plant is dormant and from 11-05~11-10.The experiment shows that the Heze peony varieties which are cultivated in pots under shack are fit to the climates of Changsha area where it is hot and wet,have good resistance and high value.These peony (Tongyun,Mulanhuanzhuang,Huhong,Juanyehong,Zierqiao,Yinhongyingyu)are suitable varieties in Hunan.
