摘要
在福建省洋口国有林场通过5个不同育苗密度的对比试验，研究杉木不同育苗密度对苗木生长量和鲜重的影响。结果表明：杉木幼苗随着育苗密度的增大，苗木生长会出现不良的趋势。其中以育苗4万～5万彬667m^2生长较好，育苗6万株／667m^2以上便出现程度不同的被压苗和徒长苗，并且苗木下部有枯枝现象。
Abstract
Five different density contrast test made in Fujian Yangkou forest farm, the effect of the Cunninghamia lanceolata (Lamb.) Hook different seedling density on seedling growth and the fresh weight were considered. The results showed that with the increase of the density of Cunninghamia lanceolata ( Lamb. ) Hook seedlings, seedling growth would bad. Among them with 40 000 - 50 000 plants a unit of area seedlings growth better, more than 60 000 plants a unit of area seedlings ap- pear different degree of small seedlings and slim seedlings, and seedlings appear flag blow the plant.
