“光辉”海棠与“红肉”苹果芽接技术

Technology on Bud Grafting of‘Guanghui'Crabapple and‘Redlove'Apple

以＂光辉＂海棠和＂红肉＂苹果当年生枝条为接穗,以山杏、李、山定子一年生播种苗为砧木,采用＂T＂形芽接及嵌芽接方法,研究了芽接时间选择、接穗部位选取、砧木选择对＂光辉＂海棠与＂红肉＂苹果芽接成活率的影响,以使＂光辉＂海棠与＂红肉＂苹果芽接成活率达到最高。结果表明：芽接时间以8月中旬至9月上旬为宜;接穗宜选当年生枝条中部枝段成活率高;砧木选取一年生播种山定子幼苗,粗度在1-2cm为宜;芽接方法以＂T＂形芽接为主,成活率较高,若错过最佳芽接时间,可采用嵌芽接法。

With annual shoot of‘Guanghui＇crabapple and‘Redlove＇apple as a scion,as well as annual seedling of the wild apricot,plum,siberian crabapple as a rootstock,‘T＇-shape bud grafting and plate budding method was applied,the effect of surviving rate on the time of bud grafting,part selection of scion for‘Guanghui＇crabapple and‘Redlove＇apple with bud were studied,and it was expected to reach the highest surviving rate of bud grafting.The results showed that the best time for bud grafting was in the middle of August to early September;central part of annual shoot was appropriately chose,and by which reached high surviving rate;annual seedling of the wild siberian crabapple as a rootstock was used,which was advisable to choose the thickness of 1-2centimeter;‘T＇-shape bud grafting was priority,which could reach high surviving rate,and if the best time of bud grafting was missed,the plate budding method was applied.
