目前,果园防护林树种选择及栽植密度已经引起人们广泛的重视,尤其是林带距果园边行距的科学距离,专家指出南侧不应少于20-30米,北侧距离不应少于10-15米,而两侧的距离是多少,至今没有明确提出。在《果树栽培学总论》、《现代化果品基地建设技术》及《果树技术培训教材》等专著中,多对林带与果树边行距离的上述提法,只是说明了南北两侧的应留空间距离,而对两侧边行距并未具体指出。所以在目前部分新建或更新果园时,有许多利用原有林带或路树做为防护林的果园,由于距离处理不当或及盲目地设置果园位置,故
At present, the selection and planting density of orchards for shelterbelts have drawn people’s attention widely, especially the scientific distance between forest belts and the orchards. Experts point out that the south should not be less than 20-30 meters and the north should not be less than 10-15 Meters, while the distance between the sides is much, so far no clear. Among the monographs such as General Introduction to Fruit Cultivation, Modern Fruit Base Construction Technology and Fruit Tree Technical Training Textbook, the above mentioned references to the distance between the forest belt and the fruit tree are merely illustrative of the space that should be left on both sides of the north and south Distance, while the spacing between the two sides did not specifically pointed out. Therefore, in the current part of the new or updated orchards, there are many orchards that use the original forest belt or road tree as shelterbelts. Due to improper handling or blindly setting orchards,
