摘要
为了筛选出核桃楸的最佳栽培密度,对长白山核桃楸幼苗进行不同栽培密度试验。结果表明:幼苗期栽培密度为1.0m×0.5m时,核桃楸幼苗株高生长与茎粗生长均表现最好,株高平均增加42.25cm,茎粗平均增加7.89mm。
In order to screen out the best planting density of Juglans mandshurlca, the different planting densi- ties ofJuglans mandshurica from Changbai Mountains were tested. The results showed that：when using plant- ing density of 1.0 m× 0.5 m, the plant height and stem diameter of seedlings were the best, plant height in- creased by average of 42.25 cm,stem diameter raised 7.89 mm.
