| 中文摘要: |
| 金叶水杉是近几年刚刚从国外引种的观赏园艺品种,因其具有树干直立、树形端庄、树冠呈宝塔形、叶色金黄靓丽、生长速度快、观赏性强等优良特性,现已成为我国园林行业彩叶树新秀。笔者研究不同时期定植的砧木、不同嫁接方法及不同嫁接时间对金叶水杉嫁接成活率及生长量的影响。结果表明:对金叶水杉前一年秋天进行砧木定植、来年2月下旬采用劈接法接穗处理最佳,嫁接成活率为94.5%。因此,嫁接时间选在每年2月下旬到3月上旬为宜,接穗当年抽梢新枝生长良好,木质化程度高,能安全越冬。 |

This study investigated the effect of stock planting at different stages, and different grafting methods and time on the survival rate and growth amount of “Gold-Rush". The result showed that the best treatment is to plant the stock in the fall of last year and to adopt thecleft graft scion in coming February, which guaranteed a survival rate of 94. 5 %. Therefore, the appropriate time of grafting is late February and Early March,which best ensures the good growth of shooting, high lignification and safe overwintering. |
