摘要
银杏因结果晚而俗称"公孙树",通过嫁接可提早结果。为探索不同的嫁接方法对银杏丰产的影响,对定植9 a的实生银杏树进行高接换冠,选用不同的接穗和嫁接方法进行试验,嫁接后第5年和第8年测定产量和树冠偏冠度。对单株产量和偏冠性进行方差分析和多重比较,结果表明:2a生和3 a生枝条高枝接换冠既能保证早期产量,又能解决银杏偏冠问题,后期丰产优势明显,可延长盛产期限。
Ginkgo biloba commonly known as ＂Gongsun tree＂ for fruiting late. To explore the effects of different grafting methods on ginkgo yield, the top crown grafting methods was used on nine year old gink- go tree, and different scion and grafting test methods also used. After five and eight years, determination of yield and partial crown degree were measured for variance analysis and multiple comparisons. The re- sults showed that top crown grafting methods used for two year and three year old branches could guaran- tee high yield, but also solve the problem of ginkgo partial crown, and extend rich period.
