摘　　要：为了提高锥栗芽苗砧嫁接成活率,以野生锥栗种子作为砧木,以‘华栗3号’当年生营养枝作为接穗,采用嫩枝劈接法,研究4个嫁接时期(4月20日、5月10日、6月1日、7月10日)、5种日龄砧木(20、30、45、60、90 d)和封口材料及封口方式(铝箔、嫁接膜封顶、嫁接膜不封顶)对锥栗芽苗砧嫁接成活率的影响。结果表明:封口材料与封口方式对嫁接成活率存在较大影响,不同的封口材料与封口方式处理的嫁接苗成活率从高到低依次为:嫁接膜封顶、铝箔、嫁接膜不封顶;6月1日为最佳嫁接时期,嫁接膜封顶处理的嫁接成活率达64.00%;砧木年龄过小(20 d)或过大(90 d)均对嫁接成活不利,当砧木日龄为45 d时,嫁接成活率最高,为69.33%。In order to enhance the survival rate of grafting in Castanea henryi using bud seedlings as rootstocks, using wild seeds in C. henryi as rootstocks and ‘Huali No.3’ as scions, the effects of four grafting dates, five rootstock ages, and seedling materials and methods on survival rate of grafting were studied by using the twig cleft grafting method. The four grafting dates were 20 April, 10 May, 1 June, 10 July. The five rootstock ages were 20, 30, 45, 60 and 90 days. The sealing materials and sealing methods were aluminium foil, scion cap sealing, and scion uncapped. The results showed that sealing materials and sealing methods had significant effects on grafting survival rate. Based on the survival rate from high to low, the order of sealing materials and sealing methods was scion cap sealing, aluminium foil, scion uncapped. The best grafting date was 1 Jun, and the survival rate reached 64% through scion caps sealing treatment. Both too young （20 days） and too old （90 days） rootstock age was not conducive to survival, and the grafting survival rate of the rootstocks at age 45 days was the highest （69.33%）.
