(一) 从1974年以来,江苏相继开展了火炬松、湿地松等38个树种种子芽移技术的试验和推广应用工作,经不断的探索,现已取得了良好的结果。 (一)摸索出了一套较为完整的林木种子的芽移技术,特别在种子处理、播种量、播种方法,温床的温、湿度控制,芽移的方法、时间,芽的长度及移后管理等方面,均有所创新。如对铅笔柏、五针松等采用药剂、热水、湿砂层积催芽的综合处理方法,将雪松、五针松种子大头朝上、小头朝下进行粒播;在芽移时间上,对有的树种采取脱壳移,有的则是带壳移;芽移与容器育苗相结合;在芽移后对各树种采取相应的有效管理措施等等。 (二)扩大了芽移树种的范围。从1984年以来,江苏进行芽移的树种已达38个。其中适合“三荒’造林的树种有8个,如湿地
(1) Since 1974, Jiangsu has carried out trials and popularized the application of seed-bud-shoot technology for 38 tree species such as Pinus taeda and Pinus elliottii. After continuous exploration, good results have been achieved. (A) to explore a relatively complete set of seedling bud technology, especially in the seed treatment, seeding rate, sowing method, hotbed temperature and humidity control, bud shift method, time, bud length and shift management And so on, are innovative. Such as the phellodendron, pine needles and other agents, hot water, wet sand stratification of the germination of the integrated treatment methods, the cedar, pine needles big head up, head down for grain sowing; bud in time, Some tree species to take shelled shift, while others are shelled shift; bud shift combined with the container seedling; buds after the removal of the tree species to take appropriate effective management measures and so on. (B) to expand the scope of bud-shifting species. Since 1984, there have been 38 tree buds in Jiangsu Province. Among them, there are 8 species suitable for afforestation in “Three Deserts”, such as wetlands
