不同移栽密度对草珊瑚苗木生长的影响

Effects of Different Transplanting Densities on the Growth of Sarcandra glabra Seedlings

于2020年在福建省三明市三元区林业局岩前林业站苗圃对不同移栽密度(株行距10 cm×10 cm、10 cm×15 cm、15 cm×15 cm)的2年生草珊瑚苗木的生长量进行调查分析。结果表明:不同移栽密度对草珊瑚苗木生长具有极显著影响,其中以株行距10 cm×15 cm最为适宜;2年生草珊瑚平均苗高27.2 cm,平均地径0.38 cm,≥5 cmⅠ级侧根平均条数9.0条,平均分枝数2.7条,平均合格苗产量达2.27万株·hm^-2。

The growth effect by different seedling transplanting densities(space 10 cm×10 cm,10 cm×15 cm,or 15 cm×15 cm)of Sarcandra glabra were conducted in the nursery of Yanqian Forestry Station of Sanyuan District in 2020,the investigation to the two-year-old seedling growth of S.glabra showed that there were highly significant difference on the seedling growth among different transplanting densities,among of which the optimal transplanting density was 10 cm×15 cm;for two-year-old seedlings of S.glabra,the average seedling height was 27.2 cm,the average ground diameter was 0.38 cm,the average lateral root(≥5 cm)article number and the average branching number were 9.0 and 2.7,respectively;the average qualified seedling yield was 22,700 plants per hectare.
