实生板栗优种嫁接后,树体营养生长过于旺盛、枝条直立,导致整形修剪困难,结果延迟,早果早丰效果不佳。在板栗嫁接次年进行拉枝刻芽,能够改善光照条件,促进光合作用,缓和树势,促发短枝,早果早丰效果显著。本文对京东板栗拉枝刻芽的方法、效果和注意事项进行了详细的论述,以期能在京东板栗生产上推广应用,切实提高京东板栗的产量与品质,促进京东板栗的产业化发展。

After grafting of superior seedlings of chestnut,the vegetative growth of seedling chestnut was too vigorous and its branches were erect, which led to difficulty in pruning and delayed fruit bearing, and the effect of early fruiting and high yield was not good.

In this paper, the methods, effects and matters needing attention of pruning and budding of "Jingdong" chestnut were discussed in detail, in order to popularize and apply in the production of "Jingdong" chestnut, improve the yield and quality of "Jingdong" chestnut, and promote the industrialization development of "Jingdong" chestnut.
