板栗是一种喜光树种,创造通风透光的生长环境是提高产量和改善品质的重要措施。目前,我省80年代种植的许多板栗林因管理没有很好跟上,已处于郁闭状态,枝叶密接,林分通风透光能力差。不仅滋生了病虫,使炭疽病、白粉病危害严重,影响板栗产量和质量,而且林冠上移、给管理工作带来了诸多不便,板栗的“疏改”已到了刻不容缓的地步。针对板栗生产现状。现将板栗的“疏改”技术介绍如下:
Chestnut is a kind of hi-light tree species. To create a light-permeable growth environment is an important measure to increase yield and improve quality. At present, many chestnut forests planted in the province in the 1980s did not keep up well due to the management. They have been in a closed state with dense branches and leaves and poor ventilation and transpiration. Not only the breeding of pests and diseases, so that anthrax, powdery mildew seriously endangering the yield and quality of chestnut, and the canopy moved to the management has brought a lot of inconvenience, chestnut “sparse change ” has reached an imperative. Chestnut production for the status quo. Chestnut now “sparse change” technology introduced as follows:
