传统山核桃林分的立体经营及其效益

Traditional Space Management and Its Efficiency of Carya cathayensis Forest

传统山核桃林分为半野生状态的粗放经营，仅在结实大年采果前林地劈山抚育１次。山核桃年生育期中，无叶期长达近半年，且林中有大块空闲地，光能和地力利用率很低。在山核桃林下补植早竹，构成山核桃·早竹的复层立体林，每年进行劈草、铲山、施肥等培育管理，经８年试验结果表明，山核桃·早竹立体林，层次明显，结构合理，能充分利用光、热、水、肥、气资源，是一种稳定、丰产、高效的复合经营方式，宜在生产上推广应用。

Traditional management of Carya cathayensis is semi - wild extensive management,one tending only in on - year before seeding.8 years experiment on planting Phyllostachys praecox with weeding. fertilizing etc.in C.cathayensis forest showed that this kind of mixed forest had advantages of evident layer, rational structure, making full use of light energy、heat、water、fertilizer、gas、and is a stable,high-yield and high-efficiency management.
