| 摘 要： | 为了丰富北方寒地优良彩叶品种,在哈尔滨地区进行了中华金叶榆硬枝嫁接方法(切接、劈接、插皮接、腹接和舌接)、保湿措施(涂保湿剂、套袋、石蜡封闭和地膜缠封)和嫁接时期(先接后栽、砧木定植1个月后嫁接和定植后次年嫁接)的引种(引自河北省)嫁接试验。结果表明,硬枝嫁接方法中,插皮接的效果最好,接穗成活率达96.7%,该种嫁接方法可在育苗生产中应用;从成本和嫁接成活率方面考虑,硬枝接穗保湿措施应采用接穗涂刷FY-1保湿剂的方法;从砧木栽植与嫁接的前后顺序上看,以栽后第2年嫁接效果最好,生产上应以第1年栽砧第2年嫁接为主。

| Abstract: | Different grafting ways (cut grafting, cleft grafting, bark-insert grafting, side grafting, and tongue grafting), moisture retention measures (moisturizer, bagging, close occluding with paraffin, and entwisting with plastic film), and grafting periods (first grafting and then planting, grafting one month after rootstock transplanted, and grafting one year after rootstock transplanted) were selected to graft Ulmus pumila cv. jinye introduced from Hebei Province. Experimental results show that the effect of bark-insert grafting is the best of all the grafting ways, exhibiting a survival rate of 96.7%. Bark-insert grafting can be used in the production of seedling cultivation. The optimal method of moisture retention is spreading FY-1 on the scions after grafted to rootstock in terms of cost and survival rate. Grafting one year after rootstock transplanted has the best survival rate. In production, grafting is usually conducted one year after rootstock planting. |
