银川地区金叶榆嫁接育苗试验

Experiment on Grafting Nursery of Ulmus pumila in Yinchuan

以金叶榆嫁接繁育试验,探讨不同砧木处理、嫁接时间、嫁接方式对金叶榆嫁接成活率的影响,筛选出金叶榆嫁接繁殖最佳技术体系,结果表明:白榆、灰榆均可作为金叶榆嫁接砧木;采用插皮接嫁接繁育金叶榆,成活率最高,达97.3%.3月上中旬生长量最大,可进行金叶榆嫁接种苗的繁育生产.

Through grafting nursery research on Ulmus pumila, we discussed various influencing factors of tile survival rate of grafting of Ulmus pumila, these factors include different methods of the processing mode of rootstocks, grafting time and grafting pattern. We find the best technical system of grafting nursery of Ulmus pumilae. The results show that ulmus pumi- la and mountain elm both can serve as Ulmus pumila rootstocks. Ulmus pumila can achieve the highest survival rate by using the method of bark grafting and the survival rate can even reach 97.3%. They have the highest growth quantity in early to mid March and we can take breeding activities of grafted seedlings of Ulmus pumila during this period.
