摘　　要：怒江下游低热河谷地区是我国诃子主要自然分布区,其中,位于怒江东岸的永德县诃子分布面积最大,达到20899 hm^(2)。2010年以来永德县先后对诃子资源实施了一系列的恢复措施:实施森林抚育7000 hm^(2),实施恢复性造林946.35 hm^(2)。为了摸清诃子在怒江下游低热河谷地区造林成效,总结诃子造林的成功经验,为今后诃子资源的恢复和产业化打下基础,进行了诃子造林成效调查分析。结合怒江下游低热河谷地区的气候特征,以诃子苗木主根发达的特性为切入点,阐述了诃子主根发达在造林工作中的运用技巧,从不同造林时间、不同苗木标准和不同的造林模式等多方面进行了分析,总结了采用3月龄无纺布袋苗、6~7月份上山造林及2年以上裸根大苗截杆造林等成功经验。The low-heat valley area in the lower reaches of the Nujiang River is the main natural distribution area of Terminalia chebula in China.Among them,Yongde County,which is located on the east bank of the Nujiang River,has the largest distribution area of Terminalia chebula,reaching 20,899 hm^(2).Since 2010,Yongde County has implemented a series of restoration of Terminalia chebula resources.7000 hm2 of forest tending and 946.35 hm^(2)of restorative afforestation are implemented.In order to find out the afforestation effect of Terminalia chebula japonica in the low-heat valley area of the lower reaches of the Nujiang River,the successful experience of afforestation of Terminalia chebula japonica is summed up,which lays a foundation for the recovery and industrialization of Hezi Fructus in the future.Combining with the climatic characteristics of the low-heat valley area in the lower reaches of the Nujiang River,and taking the characteristics of the developed taproots of Terminalia chebula japonica seedlings as the breakthrough point,this paper expounds the application skills of the developed taproots of Terminalia chebula japonica in afforestation work,from various aspects such as different afforestation times,different seedling standards and different afforestation patterns.The successful experience of using 3-month-old non-woven bag seedlings,uphill afforestation from June to July,and afforestation with bare roots and large seedlings for more than two years was summarized.
