云台山区的板栗多为实生树.由于管理粗放,大部份表现为主干高,树冠小,骨干技、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接换优,即对已结果的成年树进行修剪.结果不好、丰产性差、品质又劣的栗树,则通过嫁接,改换成优良品种.
Most of the chestnuts in Yuntai Mountain are real trees, and most of them are characterized by tall trunk, small canopy, overlapping stems, dense twigs at the top and weak and dry branches in the inner branches. (Ie, invalid branch), there is very little sticking code (ie, effective branch), which is one of the reasons for the low output.And the real chestnut nut is small, the quality changes greatly.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 trimming and grafting are now widely promoted, that is, pruning the mature adult tree. The results are poor, poor yield, poor quality chestnut trees , Then through grafting, into a good variety.
