Polygonatum cyrtonema was cultivated under the canopy of Phyllostachys edulis forests in 2013~2015, the contrast test was carried on growth effect of P. cyrtonema under the canopy of Ph. edulis forests by 3 different fertilization methods of which using potassium chloride compound fertilizer with role-fertilization, and ring-groove fertilization and radial-groove fertilization, and no fertilizer was made as control. Results showed that P. cyrtonema with radial-groove fertilization has the highest growth indicators, the average survival rate, average ground diameter, average height, average root weight were 94.9%, 0.62 cm, 65.1 cm, 1 389.62 kg/hm2, respectively; The indicators were higher than of ring-groove fertilization 4.5%, 12.7%, 9.2%, 16.3%, higher than of role-fertilization 9.5%, 26.5%, 26.5%, 26.9%, 22.5%, respectively, higher than no fertilization (control) 24.5%, 67.6%, 58.8%, 82.9%, respectively.%试验于2013～2015年期间在毛竹林冠下种植多花黄精，连续2年选用氯化钾复合肥采用穴施、环状沟施、放射状沟施3种不同施肥方法和不施肥（对照）进行毛竹林冠下多花黄精生长效果对比试验，结果表明：放射状沟施的多花黄精的各项生长量指标最高，平均保存率、平均地径、平均高度、平均根茎重量分别达94.9%、0.62 cm、65.1 cm、1389.62 kg/hm2；各项指标分别比环状沟施高出4.5%、12.7%、9.2%、16.3%，比穴施高出9.5%、26.5%、26.9%、22.5%，比不施肥（对照）高出24.5%、67.6%、58.8%、82.9%。
