摘要
火力楠(Michelia macclurei)是营造复层林、改善人工林树种的优良造林树种之一.目前玉林市林业科学研究所国家火力楠良种基地面临急需扩建和升级.为了筛选出火力楠较好的嫁接方式,通过不同处理的嫁接方式对成活率、嫁接口直径、接穗直径、接穗高度、愈合情况的影响进行研究,并利用隶属函数平均值对不同处理进行综合评价,筛选最优嫁接方式.结果表明 4 种不同处理之间的综合评价为T1＞T2＞T4＞T3,嫁接最优方式为砧木留叶皮接,T1和T2嫁接方式可以为良种基地的扩建和升级前期嫁接工作提供理论依据.
Abstract
Michelia macclurei is one of the superior trees for afforestation,suitable for creating multi-layered forests and enhancing plantation varieties.At present,there is an urgent need for expansion and upgrading at the National Michelia macclurei Superior Variety Base of Yulin Forestry Science Research Institute.To identify the most effective grafting method for Magnolia macclurei the effects of different grafting techniques on survival rate,graft union diameter,scion diameter,scion height,and healing condition were studied.A comprehensive evaluation of the different methods was conducted using the average value of membership functions to select the optimal grafting method.The results indicated that the comprehensive evaluation ranking of the four different treatments was T1>T2>T4>T3,with the optimal grafting method being bark grafting with leaves retained on the rootstock.The T1 and T2 grafting methods can serve as a theoretical basis for the preliminary grafting work in the expansion and upgrading of superior variety bases.
