核桃树耐干旱、瘠薄,适栽范围广,经济价值高,寿命周期长,是北方山区发展的主要经济林树种之一。但是,核桃从栽植到产生经济效益,一般需5~7年,前期的浇水、除草、施肥、修剪、防治病虫害等管理需要大量投入,造成果农前期经营困难,以致许多核桃林长期处于无收益状态,土地资源严重浪费。针对这种情况,根据北方地区核桃树不同生长期的特点,以充分利用林下土地资源和林荫空地为目的,选择适合林下种养的动植物,开展生态种植、养殖模式
Walnut tree resistance to drought, infertility, suitable for planting a wide range of high economic value, long life cycle, the development of northern mountainous areas is one of the main economic forest species.
