摘　　要：比较了不同橡胶树根系嫁接（根接）材料、嫁接方法和嫁接时间等因素对橡胶树根接成活的影响。结果表明：离体根接法比原地根接法的成活率高;过渡植株的顶蓬叶片物候期为稳定期和抽芽期的根接成活率高;生长旺季（4~8月）进行根接成活率高;在一定范围内随根段直径和长度增大其根接成活率提高,当进行离体根接时,根段直径4 mm以上、根段长25~45 cm为宜。Roots of rubber tree were collected and used to graft onto young budded plants at the nursery under different conditions such as rootgrafting materials,methods and time,and their survival rates were compared.The root graftings showed that the in vitro root graftings had a higher success rate than the in situ root graftings.The root-graftings had a higher success rate when the top-leaf whorl of the interim plants was at the stable leaf stage and the bud emerging stage of phenophase,and they had a high success rate in the rapid growth season from April to August and when the diameter and length of the root sections increased in a given range. The root sections 4 mm thick in diameter and 25 cm to 45 cm long were optimal for in vitro root grafting.
