摘要
为探索适用于‘广州’樱的最佳嫁接繁殖技术,以‘广州’樱为接穗,福建山樱花、大岛樱、八重寒绯樱为砧木,研究了不同嫁接时间、不同砧木种类、不同接穗茎段、不同嫁接方法及不同栽培方式对嫁接苗成活率和生长速度的影响。结果表明,在广东地区‘广州’樱冬季嫁接最佳时间为1月,嫁接60d后成活率达91.67%,嫁接1年后苗高143.34cm;以福建山樱花和八重寒绯樱作为砧木嫁接效果好,成活率分别为94.58%、93.75%,苗高分别达151.54、152.27cm;不同接穗茎段对成活率和生长速度影响较小,以顶芽及以下2个茎节稍高,成活率92.92%、苗高152.54cm;嫁接手法以切接效果最佳,成活率92.08%、苗高154.13cm;相同条件下,地苗+拱膜的栽培方法效果最佳,嫁接后成活率达95.42%、苗高169.63cm。
Grafting comparative experiments were carried out by different grafting time, stocks, scion segments, grafting techniques and cultivation methods, using Cerasus campanulata, C. speciosa, C. campanulata ＇Double-flowered＇ as stocks and C. yunnanensis ＇ Guangzhou＇ as scion. Results showed that the best grafting time of C. yunnanensis ＇Guangzhou＇ was January in Guangdong Province, the survival rate after 60 days was 91.67%, one year later the height of trees was 143.34 em. The good choice of breeding C. yunnanensis ＇ Guangzhou＇ was using the 1-year-old seedlings of C. campanulata and C. campanulata ＇Double-flowered＇ as stock, the survival rates respectively was 94.58% and 93.75%, and the heights of trees were 151.54 cm and 152.27 cm. Different parts of scion had a little effect on the survival rate and height, while the terminal buds and adjacent two sections had better effect, the survival rate was 92.92% and the height was 152.54 cm. Cut-grafting was the best choice among different grafting techniques, the survival rate reached 92.08%, and the height of trees can be up to 154.13 cm. The method with trees planted in land and covered with agricultural films was the best, the survival rate was 95.42% and the height was 169.63 cm.
