云南保山潞江镇杧果园截干换接技术初探

Preliminary Report on Grafting Techniques of Stem Cutting in Mango Orchard

通过试验观测不同换接方式、嫁接时间、嫁接方法对鹰嘴杧老树截干换接成活率和产量影响,结果表明:每年7月采果后用插枝腹接法在潞江镇鹰嘴杧老树上采用高位换接(二、三分枝回缩)金煌杧,换接成活率达84%,3年总产量65 kg/株。在二、三分枝上可换接较多接穗,最大限度地利用老果园树干,短期内就可获得较高产量,推荐使用此法对老杧果园进行截干换接。

The effect of cutting ways,grafting time and method on survival rate and fruit yield of old Mango species Golek was studied.The results showed that the replacement survival rate would reach to 84%when high position grafting with cuttings(the second and third branches were retracted)of Kim Different Mans was conducted in old Golek tree by ventral grafting method after harvested in July.The total yield is up to 65 kg per tree in three years.It`s found that the better yield would be obtained in short term when grafting with the scions from the second and the third branches in old trunk of mango orchard.
