果树嫁接一般都在春秋两季,最宜嫁接时期不过4个月左右,往往由于时间紧迫而不能完成嫁接任务,或者因拖长了嫁接时期影响成活率。因此,我场在1958年夏季进行了以梨为主的夏季嫁接试验,以寻找出夏季最适宜的嫁接时期和嫁接方法,并使接芽能在当年萌发,当年形成果苗出圃。本试验是在夏末梨树新梢腋芽已经形成,新梢基 Fruit tree grafting are generally in spring and autumn, the most appropriate period of grafting, but about 4 months, often due to the time constraints and can not complete the task of grafting, or prolonged the grafting period affect the survival rate. Therefore, my field in the summer of 1958 pear-based summer grafting trials to find out the most suitable summer grafting and grafting methods, and make the bud germination that year, then the formation of fruit and vegetable nursery. This experiment is in the late summer pear shoot axillary bud has been formed, the new shoots base
