不同光照强度对多花黄精生长的影响研究

Effects of Different Illumination on the Growth of Polygonatum cyrtonema

为了研究不同光照强度对多花黄精生长的影响,指导多花黄精林下种植,本项目以多花黄精的根茎为试验材料,对4种透光率下林地种植的多花黄精生长情况进行了统计分析。结果发现,透光率对多花黄精的物候期和生物量均有一定程度的影响,多花黄精在透光率30%~70%的林下出苗较早,生长期较长,生物量最高,根茎鲜重大。因此,在对多花黄精进行人工栽培时要控制好透光率,做好遮阴管理。

In order to study the effect of different illumination intensity on the growth of Polygonatum cyrtonema, and provide reference for the planting of Polygonatum cyrtonema, this project used the rhizome of Polygonatum cyrtonema as the experimental material to analyze the growth of Polygonatum cyrtonema planted in four kinds of light transmission rates. The results showed that the transmission rate had a certain influence on the phenological phase and biomass of Polygonatum cyrtonema, and that Polygonatum cyrtonemal appeared earlier emergence, had a longer growth period, had the highest biomass, and had a bigger fresh rhizome, under 30%~70% light transmittance forest. Therefore, the shade management should be done well and the transnlittance should be controlled when artificial cultivation of Polygonatum cyrtonema.
