摘要: <正> 前言自然森林也包括热带人工橡胶林的林地气候一般具有显著冷湿效应,我国热带纬度偏北、海拔偏高,冷季犹嫌热量不足。因而我国热带大陆垦区橡胶林,冷季常遭寒害,表现为爆皮流胶和烂脚等。在这种郁闭胶林中如间种林下作物。则林地寒湿效应将益发加剧,胶树寒害愈加严重。这一事实正是目前我国热带植胶生产上广为忧虑而又十分关切的问題。然而,林地冷湿的一般气候特征并非常年恒定,更非处处一致。与无林地比较,北方落

Abstract: The thermal-increasing efect of certain forest land has been investigated and it has some practical meanings for the rubber plantation in tropics of China. This artical is composed of three parts: part Ⅰ, The conditions for increasing the temperature inside the natural forest; part Ⅱ, increasing the temperature features of the intercropping rubber forest; part Ⅲ, the intercropping rubber forest with over crown canopy (by deciduous or sparse tree crown)in cold season is a reasonable community structure for building cold resistant rubber plantation("Biological cold-resistant structure).
