摘　　要：[目的]延长杉木种子园嫁接时间,缓解劳动力紧张,提高嫁接成效。[方法]以赣州市崇义县高坌林场2代种子园中2年生实生杉木苗为砧木,探究不同嫁接方法、接穗类型、砧木大小、套袋与否对杉木冬季嫁接苗成活率、正冠率、接穗高生长量和粗生长量的影响。[结果]除不同砧木大小外,不同嫁接方法、接穗类型、套袋与否对杉木冬季嫁接后成活率、正冠率、接穗高生长量和粗生长量的影响均达到显著差异。分别以切接、带顶芽接穗、套袋表现最佳,接株成活率、正冠率、接穗高生长量和粗生长量分别为96.6%、82.8%、49.7 cm和11.12 mm。[结论]在进行杉木种子园冬季嫁接时,使用切接的嫁接方法,采用第一段带顶芽的粗壮穗条作为接穗,在3 cm左右的砧木进行嫁接,接后做好接后套袋管理,效果最佳。为生产中提升杉木种子园嫁接成效提供了新的方法。[Objective]To prolong grafting time of Cunninghamia lanceolata seed orchard,relieve the labor shortage and improve the grafting effect.[Method]The effects of different grafting methods,scion type,rootstock size,bagging or not on the survival rate,positive crown rate,high scion growth and coarse growth of Cunninghamia lanceolata grafted seedlings in winter were investigated by using 2-year old Cunninghamia lanceolata seedlings in the 2nd generation seed garden of Gaobeng Forest Farm,Chongyi County,Ganzhou City.[Result] In addition to different rootstock sizes,different grafting methods,scion types,bagging or not had significant differences on the survival rate,positive crown rate,high scion growth and coarse scion growth after grafting in winter.The graft survival rate,positive crown rate,high growth and coarse growth of scion were 96.6%,82.8%,49.7 cm and 11.12 mm,respectively.[Conclusion] In the winter grafting of Cunninghamia lanceolata seed garden,the best effect is to use the cutting grafting method,using the first section of thick spike with terminal bud as scion,grafting on the stock of about 3 cm in size,and doing the bagging management after grafting.It provides a new method for improving the grafting effect of Cunninghamia lanceolata seed orchard in production.
