板栗是辽宁东部山区的一个重要经济树种,在桓仁县已有50多年的生产历史。但品种混杂,劣质品种多,品种结构不合理,经济效益不高。几年来我们对劣质品种树进行高接更新,从中总结出板栗树“早接、多头、套袋”的高接技术,实现了高接当年恢复树冠,次年开始结果,第3年丰产的目的。试

Chestnut is an important economic tree species in the eastern mountainous area of ​​Liaoning. Huanren County has more than 50 years of production history. However, mixed varieties, inferior varieties, irrational variety structure, economic efficiency is not high. In recent years, we have carried out high pick-up and renewal of low-quality tree species. From this, we conclude the high pick-up technique of chestnut tree “early pick up, long pick up and bagging” and achieve the goal of recovering the canopy crown the same year, . test
