摘要
通过对全国29个重点产栗县54块丰产园连续4年的调查研究指出:实生栗林平均亩产111.1kg,嫁接栗林平均亩产135.4kg,采用的主要技术措施是:适地栽栗、良种嫁接、加强土、肥、水管理、合理整形修剪,搞好病虫害防治和适时采收等工作。同时,对当前板栗生产中存在的问题和解决途径进行了探讨。
We made a four-year investigation into fifty-four of China's high-yield chestnut (Castanea mollissima) stands across twenty-nine counties. The results show that the mean yield of seedling stands was 1666.5kg per ha and that of grafted stands 203lkg per ha.The cultivation techniques can be generalised into six aspects, i.e.to select the var iety according to site conditions; to use grafts of improved var ieties; to strengthen soil, manure and water management; to train the tree form to
make the best use of the land and solar energy; to carefully attend to
pest control; and to harvest in the proper time.The investigation is also concerned with a discussion of the problems existing in the country in chestnut production and the corresponding solutions.
