【摘要】 本文对水曲柳萌芽林和26年生水曲柳红松混交林的部分调查研究表明,选择水曲柳母树伐根径级应在5—25 cm之间、龄级在5—25 a之间;采伐季节在秋冬季均可;立地条件应选择在山的中、下腹;坡向的顺序为阴坡、半阴坡、半阳坡,不宜选在阳坡。混交方式应选择水曲柳窄带状或根据水曲柳萌芽状况进行随机混交,混交比一般应为5水5红或水曲柳比例较小为宜。更多还原

【Abstract】 In this paper, some investigations have been made on a sprouting F. mandshurica forest and a 26 year old F. mandshurica and pinus koraiensis mixed forest. The results indicate that the selective base diameter size class for F. mandshurica sprouting should in the range irom 5cm to 25cm, age class should be in the range of 5—25 year. The site should be in the middle or lower parts of the mountain. The aspects order for cutting should be shade slope, semi-shade slope, semi-sunslope. The mixed pattern for the two tree species should be in the way of narrow F. mandshurica belt or random mixed according to the pattern of Fraxinus raand shurica sprouting. The general ratio of mixing should be 5∶5. Certainly, the proportion of F. mandshurica can be comparatively lower.更多还原
