摘　　要：为了了解除萌对蛇皮果萌条生长的影响,以进一步探寻适合蛇皮果的除萌措施,对文昌和澄迈蛇皮果林地除萌植株和未除萌植株进行了定期的监测,研究结果表明：（1）除萌后4个月内,除萌母株萌条数大于未除萌母株,4个月后,除萌母株萌条数小于未除萌母株,除萌可以使萌条集中萌发,便于萌条管理,但仅用刀砍的除萌方法未能有效除萌;（2）在澄迈,除萌母株和未除萌母株叶总长增量相差不大,而在文昌,除萌母株叶总长的增长量小于未除萌母株,即总体上除萌对萌条叶生长影响不大,但在逆境下,除萌抑制萌条叶生长;（3）澄迈蛇皮果林地以4～6月份为萌条高峰期,以4～10月份为生长高峰期,文昌蛇皮果林地以12月到翌年2月份为萌条高峰期,以8～10月份为生长高峰期,澄迈应在6月中旬后及时除萌,文昌应在2月中旬到8月中旬间除萌。The number of sucker and leaf length were investigated for young plants of Slacca zalacca with and without suckers in Chengmai and Wenchang.The results show that（1） removing sprouts promoted S.zalacca to sprout within 4 months,but had negative effect on S.zalacca’s sprouting after 4 months;（2） The effect removing sprouts taken on growth of S.zalacca’s sprouts was depended on site conditions,the removing sprouts had no evident effect on growth of S.zalacca’s sprouts in Chengmai,but had negative effect on growth of S.zalacca’s sprouts in Wenchang;（3） The fast-sprouting period and the fast-growing period of S.zalacca were respectively from April to June and from April to October in Chengmai,the fast-sprouting period and the fast-growing period of S.zalacca were respectively from February to April and from August to October.In Chengmai,the suckers should be removed timely after the middle of June.In Wenchang,the suckers should be removed between February and August.
