日本专家诚阪光弥先生于１９９５年１０月来辽宁省进行了栗树栽培技术交流。建议根据立地条件，新建栗园的株行距以３～５ｍ，４～５个品种混植为宜。当树龄达１０年左右实行适时间伐；冬剪时盛果期树应根据果型大小，剪去２／３～３／４；实生大树嫁接改优时，可先更新后嫁接；对栗实象鼻虫的防治应以采收后药剂熏蒸为主；栗园土壤管理采用生草法；改变打苞采收，改进保鲜及加工技术。还指出，应尽快扩大适合加工用的大果型日本栗品种的栽培面积，提高经济效益；在栗产区建立栗果出口的半成品加工厂，实现产地增值。笔者根据辽宁的特点结合专家建议确定了健康发展的方向。
Japanese expert Kenji Sakamoto came to Liaoning Province in October 1995 for exchange of chestnut cultivation techniques. Suggestions based on site conditions, the new Chestnut row spacing to 3 ~ 5m, 4 ~ 5 varieties planting appropriate. When the age of about 10 years to implement the appropriate time cutting; winter shears full-fruit trees should be based on fruit size, cut 2/3 ~ 3/4; grafted tree improved, grafting can be updated first; Weevils should be controlled by fumigation after harvest; Chestnut soil management using grass-law; change buds harvest, improve preservation and processing technology. He also pointed out that the cultivation area of large-size Japanese chestnut varieties suitable for processing should be expanded as soon as possible and the economic benefits should be raised. A semi-finished product processing plant for exporting chestnut fruits should be established in the chestnut production area to realize the added value of origin. The author, based on the characteristics of Liaoning combined with expert advice to determine the direction of healthy development.
