1986年在建德林场进行了三项银杏嫁接试验:①用采自1株雄树的接穗,分别在1～2龄和3～4龄苗砧上以切接、劈接、合接、腹接和插皮接5种方法嫁接,按裂区设计,重复3次,每小区接8株:②用采自60株雌树(无性系)的接穗以劈接法嫁接,按完全随机区组设计排列,3个区组,第1、2、3区组分别为8、9、10株小区;③用已嫁接成活生长1年的13个雌树无性系的嫁接苗,按完全随机区组设计进行栽培试验,5个区组,2株小区,株行距5×5m,年底测定嫁接成活率和各年度的新稍生长。数据分析表明:砧龄×接法的交互作用引起成活率的显著差异,1～2龄砧用劈接,3～4龄砧用合接最好。不同无性系间在嫁接成活率和1、2、3年新梢生长上都有极显著差异。各年度新梢生长具密切相关,它们与嫁接成活率的相关不紧密。认为愈合能力和生长速度都受到无性系的控制。
In 1986, three ginkgo grafting experiments were carried out in Jiande Forest Farm. ① Scion taken from a male tree was cut, split, connected, and abdomen on 1-2 and 3 to 4-year-old seedlings respectively Grafting and grafting five methods of grafting, according to the design of the fracture zone, repeated 3 times, each cell connected to 8 strains: â’¡ with 60 female trees (clones) scion split by grafting approach, according to a completely randomized block Design arrangement, 3 blocks, 1, 2, 3 groups were 8, 9, 10 cells; ③ grafted survival of 13 grafted survival clones of 13 clones, according to completely randomized block The cultivation experiment was designed. Five district groups and two small plots with a row spacing of 5 × 5m were used. The grafting survival rate and new growth of each year were measured at the end of the year. Data analysis showed that the interaction of anvil × connection caused a significant difference in survival rate, 1 ~ 2 anvil with cleavage, 3 ~ 4 anvil with the best connection. The clonal survival rates of different clones and the growth of shoots at 1, 2 and 3 years were significantly different. The annual shoot growth is closely related to their grafting survival rate is not closely related. It is believed that healing power and growth rate are controlled by clones.
