摘要
为了提高皇冠梨嫁接成活率和生长量,研究了不同嫁接方法(丁字形芽接、嵌芽接、单芽切接、劈接和腹接)对苗木成活率、生长量、芽体发育、出圃等级和嫁接口愈合程度的影响。结果表明:腹接的嫁接成活率、苗木高度、粗度、整形带内饱满芽数量和出圃时1级苗所占比例均最高,分别为93%、114cm、0.92cm、15.8个和70%。除此之外,嫁接口愈合率也较高,为91%,在生产中可推广这一嫁接技术来提高皇冠梨苗木成活率和生长量。
In order to increase survival percent and growth of Pyrus bretschnelder Rehd grafting seedlings, the effects of different grafting methods ＂T＂ bud grafting, plate budding, single bud cutting, cleft grafting and side grafting on survival percent, growth, bud development, grade, healing degree were studied. The result showed that the survival percent, height, diameter, number of full bud in plastic belt, percent of one grade of grafting seedlings of side grafting method were the highest in all treatments, which were 93%, ll4cm, 0.92cm, 15.8 and 70%. In addition, healing percent of grafting union was the higher, which was 91%, the side grafting method was extended to increase survival percent and growth of Pyrus bretschnelder Rehd grafting seedlings.
