结合秦安县五营镇桃苗木繁育生产工作实践，研究了砧木密度、嫁接时期、接芽愈合周期以及接芽不同包扎方法对桃苗木嫁接愈合的影响。结果表明，秋季桃苗嫁接适宜的砧木密度为120 000株/hm2，嫁接时期宜在9月下旬之前，包芽包扎方式也有利于秋季嫁接芽的愈合。

Based on the practice of peach seedling breeding and production in Wuying Town， Qin'an County， the effects of rootstock planting density， grafting period， grafting healing cycle and different dressing methods on peach seedling callus at festival were studied. The results showed that the optimum rootstock density for autumn peach seedling grafting was 12 000 plants/hm2， and the suitable grafting time was before the end of September. The wrapping method of buds grafting was also conducive to the healing of grafted buds in autumn.
