采脂的实践告诉我们在同一径级、同一立地条件下的马尾松,采用同一采脂方法,它们之间的单位面积产脂量却是不相等的。高的每平方厘米割面产脂量可达二十克,低的却小于一克,高低相差十倍乃至二十倍,主要原因在于形态。探讨马尾松各种形态的产脂量,掌握它的规律,对于指导松脂生产以及人工营造采脂林具有现实意义。其一,以形态识别马尾松产 Lipid practice tells us that in the same diameter class, the same site conditions Masson pine, using the same method of liposomes, fat production per unit area between them is not equal. High per square centimeter cutting fat production capacity of up to 20 grams, low but less than one gram, the level of a difference of ten times or even twenty times, mainly due to morphology. It is of practical significance to study the production of Pinus massoniana in various forms and to grasp its regularity, which can be used to guide the production of pine resin and to create artificial forests. First, identify the masson pine production
