乡土杨梅嫁接改造试验

Experimental Study on Grafting Transformation of Local Bayberry Tree

通过对乡土杨梅进行不同嫁接季节、不同嫁接方法和不同嫁接防护措施等处理,于次年5月份对其成活率进行调查分析,结果表明,春季是进行乡土杨梅嫁接改造的最适时间,嫁接成活率比夏秋季高,平均达35%,其中插皮接可达54.15%;根据嫁接口砧木的大小可采用不同的嫁接方法,除春季采用插皮接成活率较高外,其他嫁接方法对成活率的影响不显著;但因春季气候干燥,同时采用接穗套袋保湿加牛皮纸遮荫的处理措施,成活率会更高,可达56.4%。通过方差分析表明,不同嫁接季节、不同嫁接防护措施差异显著,不同嫁接方法差异不显著。

Grafting transformation experiments on local bayberry trees in Lufeng county of Yunnan province were conducted,the experimental treatments include different grafting season,different grafting method and different protection measures.The results indicated that spring is the best time for grafting transformation,with the average survival ratio of 35 %,the survival ratio of bark grafting obtains 54.15 %.Except high survival ratio of bark grafting conducted in spring,there is no significant difference between different grafting methods.Grafting in spring,it is necessary to protect the scion through carefully wrapping it,covering it with bag and shading it with brown packing paper,with appropriate protection,the survival ratio can achieve 56.4 %.The results of variance analysis showed that the survival ratio differences of different grafting seasons and different protection measures are significant,whereas the difference from grafting methods was not significant.
