摘要
为充分了解甘肃紫斑牡丹引种洛阳后其茎叶生长规律及物候期情况,对从甘肃兰州引进的能够在洛阳地区生长开花的20个紫斑牡丹品种的茎叶生长规律及物候期进行研究。结果表明:洛阳地区紫斑牡丹的萌发期为2月下旬;3月20日-4月6日为牡丹茎生长高峰期,此间平均生长量达21cm,4月20日已完成茎全年生长量,年平均生长量为30.36cm;3月底至4月上旬是叶片的迅速生长期,4月22日叶片大小定形,其平均叶长、叶宽分别达到31.16、21.73cm;花期集中在4月13-23日。
In order to fully understand the growth law of stem and leaf and phenology of Gansu purpura peony introduced to Luoyang,the growth law of stem and leaf and phenophase of 20 Paeonia rockii cultivars were studied.The results showed that the germination stage in Luoyang was late February; The growth peak period of peony stem was from March 20 to April 6,with an average growth amount of 21 cm.The annual completed growth of stem was on April 20,with an average growth amount of 30.36 cm.The rapid growth phase of the blade was in late March to early April,and leaf figuration was on April 22,with average leaf length of 31.16 cm and leaf width of 21.73 cm,respectively.Flowering was concentrated from April 13 to April 23.
