D01杨树从美国的阿肯色州引种到长江中游洞庭湖流域的低山、湖滨地段以及长江南面的红壤丘陵地带。对D01杨树的引种调查研究表明:D01杨树繁殖容易、萌芽力强、生长周期短;无性扦插木的年生长量变化呈“M”形;D01杨树在初夏生长迅速,秋季中期后落叶并进入休眠期,次年三月再次萌芽,其年生长周期为6个月;昼夜温差、年平均气温和日照时间是影响D01杨树生长的主要气象因子。 D01 Poplar was introduced from Arkansas in the United States to the low mountains and lakeside sections of the Dongting Lake basin in the middle reaches of the Yangtze River and the red soil hills to the south of the Yangtze River. The investigation on the introduction of D01 poplar showed that poplar D01 was easy to propagate, with strong germination and short growth cycle. The annual growth of vegetative cuttings showed “M” shape. Poplar D01 grew rapidly in early summer and mid-fall After falling leaves and into the dormant period, germination again in March next year, the annual growth cycle of 6 months; day and night temperature, annual average temperature and sunshine duration is the main meteorological factors that affect the growth of D01 poplar.
