摘要:
为了提高香榧接穗嫁接成活率和新梢生长量，以培育3 a的当地榧树实生苗和诸暨枫桥的香榧枝条为材料,分别于2019，2020年3月进行香榧苗木嫁接试验,当年10月下旬统计劈接、切接、插皮接、贴枝接 4种嫁接方法的接穗嫁接成活率、测定年新梢长度和基径。结果显示，嫁接方法对嫁接后接穗成活率有极大影响，4种嫁接方法的接穗嫁接成活率最高的是插皮接（2 a平均成活率为92.80%），比最低的贴枝接（2 a平均成活率为58.18%），提高34.62%，达极显著差异(P=0.000 1)。插皮接新梢基径、新梢生长量最高，分别为4.57 mm,22.29 cm，新梢基径最低的是劈接4.45 mm，新梢生长量最低的是切接21.44 cm，贴枝接的新梢基径和新梢生长量均居于第3，不同嫁接方法之间，新梢基径、新梢生长量虽有差异，但差异不显著(P＞0.846 2)。因此，采用嫁接技术培育无性繁殖的香榧苗时，应优先考虑插皮接方法，然后再考虑用切接法或劈接法。
Abstract:
To improve the growth of new shoots of Torreya Grandis ‘Merrillii’, using Chinese Torreya seedlings aged 3 as rootstock, the scion survival, the base diameter and length growth of new shoots were subsequently studied with such 4 propagation methods as split grafting, cut grafting, skin grafting and stick grafting. The results showed that the grafting method had a great influence on the scion survival. Two years after graft, among 4 methods, skin grafting could get the highest survival (92.80% on average), 34.62% higher than that of stick grafting (58.18% on average, the lowest), with extremely significant difference (P=0.000 1). The base diameter and length growth of new shoots with skin grafting could reach the highest (4.57 mm, 22.29 cm) while the base diameter of the new shoot with split grafting got the lowest (4.45 mm). And the lowest shoot growth was found in cutting grafting (21.44 cm). Stick grafting performed thirdly in the base diameter and shoot length growth. There were no significant differences in the base diameter and shoot growth among 4 methods. So we concluded that using graft to asexually breed T. grandis ‘Merrillii’, skin grafting should be first considered, and cut grafting or split grafting considered next.
