山丁子高枝嫁接小苹果防止腐烂病研究

针对我国大苹果和小苹果树体腐烂病一直严重发生、导致毁园快的问题,利用野生山丁子抗腐烂病强的特点,在山丁子1.2～1.5m高的主干上,高位嫁接小苹果品种引俄1号和黄太平,并在1.5m高主干向下选3～5个山丁子侧枝,在距离每个侧枝基部30～40cm位置(也是易患腐烂病部位)嫁接小苹果品种,培养高接的3～5个主枝。同时采用多主枝的细长纺锤形整形方法。结果表明:与苹果低位嫁接栽培和普通高接栽培比较,山丁子高枝嫁接小苹果腐烂病降低90%以上,且不会出现因腐烂病毁园的问题。

Study on Preventing the Occurrence of Rot Disease by High Branch Grafting on Baccata

For the serious rot disease occur in apple orchards in China,many orchards suffered losses so serious that had to be abandoned.Using wild mountain small sub-feature of strong anti-rot disease as stock,grafting small apple varieties lead Russia No.1 and Huangtaiping on 1.2 ~ 1.5 m high of the trunk.A height of 1.5 m,down select three to five collateral,graft apple varieties at 30 ~ 40 cm from each lateral branch of the base location,where susceptible to rot disease site.Develop three to five main branches.At the same time,the main branch of the thin multi-spindle shaping method was used.The results showed that:using this method could lower more than 90% rot diseases compared with low grafting apple cultivation and grafting cultivation.The fruit park will not be destroyed by these rot diseases.
