摘要：

为探索出繁育灰楸苗木的理想方法,通过用砧木年龄、砧木类型、接穗处理、嫁接方法的多组重复试验,研究不同嫁接方法培育的苗木成活率和生长量。在嫁接成活率上,芽接和枝接有显著性差异,芽接比枝接成活率高出30个百分点;带木质部芽接培育的苗木成活率为92%;在同一时间进行嫁接,砧木为梓树和黄金树的嫁接成活率较高,最差的为滇楸,其次为楸树、灰楸;在生长量上,砧木年龄越大,嫁接苗苗高生长量越大,春季采条的生长量普遍高于沙藏越冬和冷库越冬。灰楸春季用带木质部芽接法培育的苗木成活率高,长势好,应大力推广应用。

摘要：

To explore ideal method of breeding on Catalpa fargesii seedlings,the survival rate and growth of seedlings were cultivated by studying different grafting methods such as:multiple sets of repeated trials including stock age,type of stock,scion treatment and grafting methods.The survival rate of seedlings with bud grafting had a significant difference with that of seedlings with scion grafting,and it was 30% higher than that of seedlings with scion grafting;the survival rate of grafting seedlings with xylem bud reached to 92%.The survival rate of Catalpa ovate and Sapindus mulorossi seedlings for grafting at the same time was highest,Catalpa bungei and Catalpa fargesii was higher,and Catalpa duclouxii seedlings had the lowest survival rate.Stock age was older,increment of the seedlings using grafting with older root stock was higher,and seedling grafted in spring was generally higher than that through stratification and cold storage for overwintering.The survival rate and growth of Catalpa fargesii seedlings grafted with xylem bud in spring was relatively higher,so it should be vigorously promoted for application.
