【摘要】 观察扶芳藤的物候期,研究扶芳藤的生长规律及攀附特性。扶芳藤萌芽早,花蕾生长期长,种子成熟期晚,当年生叶片冬季不脱落,休眠期晚;扶芳藤年生长期长,一个生长周期会出现两次生长高峰,其新梢的年生长、节间及叶片生长规律遵循Logistic方程的拟合曲线;常绿直立型向阳性好,匍匐生长型耐荫能力强;不同的扶芳藤类型适宜于攀援不同角度,常绿直立生长的扶芳藤类型攀援于近90o的攀附物时生长速度大,随角度的减小高生长量成规律性递减;冬季红叶匍匐生长的扶芳藤类型则在攀援于近50o的角度时生长速度最快。更多还原

【Abstract】 The experiment observed phenophase,growth rule and climb character of Euonymus fortunei.It’s germinates early.Bud growth period is long.Seeds maturate late.The leaves of current year don’t fall.Its dormancy is late.The year growth period is long.There are two faster peaks in one growth period.The new branches,stems and leaves’ growth rule follow Logistic equation curve.The ever green erect type is apricus.The creepy type is able to bear shade.Different type can climb different angle.The ever green erect type grows fastest when climb angle of 90°.It grows slow with the decline of climb angle.The creepy type with red leaves in winter grows fastest when climb angle of 50°.更多还原
