山东省的板栗生产,长期以来多为实生,大冠稀植,管理粗放,致使结果迟(7—8年开始结果,15年生才进入盛果期),产量低(40～100斤/亩)。自1963～1965年嫁接技术过关后,板栗生产逐步走上良种嫁接、密植矮化和科学管理的路子。目前,山东省达到以上要求的丰产园有4万余亩。其中涌现出不少稳产高产和早期丰产的典型,现举实例列入下表。
The production of chestnut in Shandong Province has long been mostly real, large crown sparse planting, extensive management, resulting in late results (7-8 years results, . Since 1963 ~ 1965 after grafting technology, chestnut production gradually embarked on planting grafting, planting dwarf and scientific management. At present, Shandong Province has reached more than 40,000 acres of high yield garden. Among them, many typical examples of stable and high-yielding and early high-yielding emerged. Examples are listed below.
