云台山区的板栗多为实生树。由于管理粗放,大部分表现为主干高,树冠小,骨干枝、侧枝重叠,顶端小枝密生,内膛枝细弱、干枯。多为鸡爪码、香头码(即无效枝)很少有棒槌码(即有效枝),这是产量不高的原因之一。而且实生栗树坚果小,品质变化大。为了提高板栗的单位面积产量和栗实品质,加强土、肥、水管理是十分重要的。在技术措施上,现在普遍推广整形修剪及嫁 Chestnut Yuntai mountain mostly real trees. Due to extensive management, most of the performance of the trunk high, small canopy, trunk branches, lateral branches overlap, the top branches close, the inner branch of the thin, dry. Mostly chicken code, sweet code (ie, invalid sticks) Few bar codes (effective branches), which is one of the reasons for the yield is not high. And real chestnut nuts small, large changes in quality. In order to improve chestnut yield per unit area and chestnut quality, it is very important to strengthen soil, fertilizer and water management. In technical measures, plastic trim and marrying are now widely promoted
