通过对湖南省范围内四川桤木成林、中林、幼林调查,总结出四川桤木在湖南的生长情况及适应性:(1)种源丰产性由大到小排序为邛崃、夹江、珙县、冰川、都江、金堂、盐亭、雅安;(2)四川桤木喜爱高水肥,而不耐干旱瘠薄,易受风吹、雪压之害;(3)前期生长快,后期生长明显减慢且个体分化大,建议轮伐期不超过12年。 Based on the investigation of forestation, middle and young stands of Alnus cremastogyne in Hunan province, the growth and adaptability of Alnus crest in Hunan were summarized as follows: (1) The order of seed yield from high to low was 邛 崃, Jiajiang, Juxian, Yanting, Ya’an; (2) Alder of Sichuan prefers high water and fertilizer, but is not able to tolerate dry and infertile infertility. It is susceptible to wind and snow pressure; (3) Rapid growth in the early stage and late growth Significantly slowed down and individual differentiation is large, the proposed rotation of not more than 12 years.
