摘　　要：采用黄花倒水莲2年生组培移植苗在阔叶树林冠下按照株行距40cm×60cm、50cm×60cm、60cm×60cm、60cm×80cm栽植,分析比较黄花倒水莲生长情况。结果表明:黄花倒水莲阔叶树林冠下不同栽植密度的保存率、地径、株高、根茎总重量以株行距60cm×60cm栽植最高,平均保存率、地径、株高、根茎总重量(干重)分别为97.8%、2.02cm、112.6cm、696.71kg/hm2。The 2 years of Polygala fallax Hemsl. was cultivated with planting spacings of 40 cm×60 cm, 50 cm×60 cm, 60 cm×60 cm and 60 cm×80 cm. Its growth situations were analyzed and compared. The results showed that with the planting spacing of 60 cm×60 cm, it had the highest preserving rate ground diameter, height ang total root weight. The average preserving rate reached 97.8%, the average ground diameter was 2.02 cm;the average height was 112.6 cm;and the average root total weight was 696.71 kg/hm2.
