摘要
在种植滇黄精和半夏的云南松林地,连续3年开展观测实验,分析研究林下种植药材对云南松树高生长的影响。结果表明:林下种植滇黄精和半夏的实验木高生长量比参照木大0.58 m,平均每年实验木比参照木高生长量大0.178 m。因而得出以下结论:在云南松同一生长期内,林下种植滇黄精和半夏的云南松林木高生长量明显大于相同森林经营水平下的其他云南松林木的高生长量;在云南松林下种植滇黄精和半夏,能够促进云南松林木高生长。
An observation experiment was conducted over three consecutive years in a Pinus yunnanensis Franch forest planted with Polygonatum kingianum Collett&Hemsl.Pinellia ternata to analyze the effects of understory medicinal planting on the height growth of Pinus yunnanensis Franch.The results indicated that the height growth of trees in the experimental group(with understory planting)exceeded that of the control group by 0.58 m,with an average annual difference of 0.178 m.It was therefore concluded that:during the same growth period of Pinus yunnanensis Franch,the height growth of trees in plots with understory planting of Polygonatum kingianum Collett&Hemsl.and Pinellia ternata was significantly greater than that of trees in control plots under similar forest management conditions;the understory cultivation of Polygonatum kingianum Collett&Hemsl.and Pinellia ternata can promote the height growth of Pinus yunnanensis Franch.
