通过对甘肃康南林区近十年日本落叶松植苗造林后,幼林生长状况连续调查对比分析显示:本区整体对日本落叶松造林适宜、树种适生,但不同立地要素对日本落叶松幼林生长影响显著。选择最佳地域造林,其丰产性能得到极大发挥,生长迅速,林木生长势强,林地生物量积累快,生产力高,极丰产,树种抗逆性明显增强;选择次生区造林,其丰产性能不同程度受阻,制约了本树种速生、丰产特性,林分生长状况差于优生区。
Through continuous investigation and comparison of the growth status of young larch in Conaximu forest area of Gansu Province in recent ten years, the results of continuous investigation showed that the whole area is suitable for afforestation of Japanese larch and the tree species is suitable for living, but different site factors have significant effects on the growth of young Larix kaempferi . Select the best area afforestation, its high yield performance has been greatly exerted, rapid growth, strong forest growth, forest biomass accumulation, high productivity, very high yield, tree species significantly increased resistance; selection of secondary afforestation, its high yield performance Different degrees of resistance, restricted the rapid growth of this species, high yield characteristics, stand growth is worse than the eugenic area.
