摘要
以河北省迁西县板栗＇燕山早丰＇芽苗和1年苗为砧木,＇燕山早丰＇、＇大板红＇和＇2005-1＇为接穗,采用Parafilm封口膜、塑料条、铝箔和中性密封胶为封口材料,进行单芽砧、双芽砧及1年砧嫁接试验,研究了封口材料与砧穗不同组合对嫁接愈合时间、成活率及新梢生长的影响。结果表明：3个板栗品种中,以＇燕山早丰＇为接穗时成活率最高,达到78.1%;Parafilm封口膜更有助于接口愈合,成活率达到81.4%,且愈合仅为17.3d,比其它材料缩短愈合时间3-6d;1年幼砧嫁接成活率高达91.1%,新梢生长量为19.4cm,显著优于芽砧嫁接,双芽砧显著优于单芽砧嫁接,但后期生长仍需进一步观察。
Taking Castanea mollissima Bl.‘Yanshan Zaofeng＇and 1-year-old rootstock of it,using‘Yanshan Zaofeng＇,‘Da Banhong＇and ‘2005-1＇as scions,using Parafilm,plastic strip,aluminum foil,sealant as sealing materials,as materials,the effects of binding material,rootstock types and scion varieties on survival rate,average germination time and shoot growth were studied.The results showed that,within grafting of three Castanea mollissima Bl.,the scion varity‘Yanshan Zaofeng＇was significantly better than other scion varieties with survival rate 78.1%;Parafilm plastic packaging was significantly better than other binding materials on chestnut grafting survival rate with 81.4%and average germination time（17.3days）of chestnut it was shorter 3—6days than other materials,1-year-old rootstock was the best rootstock type than others on survival rate with 91.1%,double-rootstock grafted bud seedling was significantly better than single-rootstock grafted bud seedling.
