【摘要】 本文从胡桃楸(Juglans mandshurica Maxim)、落叶松(Larix olgensis Henry)混交林树干生长过程、根系垂直分布和不同立地条件不同混交比)的林分生长状况等不同角度,讨论了混交林生长和种间关系,肯定了胡落混交是成功的。在立地条件好的情况下,混交林种间关系协调,单位面积蓄积量是胡桃楸纯林的1.69倍。混交以带混为宜,落叶松带3—5行,胡桃楸带1—2行;不宜采用株间混交。应选择土层深厚肥沃、水分条件好的立地条件上营造胡落混交林。更多还原

【Abstract】 From aspect of stem growth, vertical distribution of rootsystem and growth situations of the stands on different sites and in different mixing ratio ect, of the mixed forest which is composed of Juglans mandshurica and Larix olgensis, this paper has discussed thee growth and interspecific relationship of the mixed forest. It is assured that mixing silviculture of J. mandshurica and L. olgensis is successful. On the good sites, the mixed forest has a coordinated interspecific relationship, and the stand stocking per hectare is 1.69 times more than that of pure J. mandshurica forest. It is suitable for making belt mixing of the two species. The belt for L. olgensis should be 3—5 rows, and 1—2 rows for J. mandshurica. It is not appropriate to make individual mixing of the two species. Sites of deep layer and fertile soil and good water condition should be selected for the cultivation of the mixed J. mandshurica and L. olgensis forest.更多还原
