1、探析马尾松栽培管理技术 马尾松(Pinusmassonianalamb.)是我国分布最广、数量最多的一种松树,在南方各省森林蓄积量中,马尾松占一半以上。马尾松喜光,要求温暖湿润的气候,对土壤要求不严,能在石砾土、沙质土、粘土、山脊及岩石裸露的石缝里都能生长。忌水涝,不耐盐碱,喜酸性和微酸性土壤,pH值4.5-6.5生长最好。在钙质土和石灰岩风化的土壤上往往生长不良。 Massonpine(Pinusmassonianalamb.)isthemostwidelydistributedinChina,thela

6、要根据树种特性和立地条件,因地制宜,合理布局,使之与阔叶树混交,既有利于水土保持和改善森林生态环境,又有利于预防马尾松毛虫的蔓延发展和森林火灾发生。应根据经营目的,交通条件,培养不同的材种,以便分别采取相应的经营措施,充分发挥马尾松的生产潜力。 Massonpineplantingareashouldnotbeconcentratedlargearea,accordingtotreespeciescharacteristicsandsiteconditions,adjustmeasurestolocalcon
