摘 要: | 采用40%、50%、60%割面负荷率和天天割、隔天割的采脂方法,对不同密度的12、17和22年生马尾松林分进行采脂试验,结果表明,采割间隔期越短,割沟越长,越有利于松脂分泌;天天割的单位面积产脂量是隔天割的1.28倍,60%割面负荷率的平均单株单刀产脂量是40%、50%割面负荷率的1.19和1.07倍;中龄林采取40%割面负荷率和隔天割,近成熟林采取50%割面负荷率和隔天割的采脂方法,不但可获得较好经营效益,而且可延长采脂经营年限。

Abstract: | This study aimed to conduct resin tapping under different density forest of 12a,17a and 22a Pinun massoniana with tapping burden rate of 40%,50% and 60% at a tapping interval period of every day and next day.The results showed that the shorter the tapping interval period was,or the longer the tapping ditch was,the more resin yield was;the per unit resin yield tapped everyday was 0.28 times more than that of next day tapping;the average singletree and single-bark resin yield with a tapping burden rate of 60% was 1.19 and 1.07 times respectively more than that with a tapping burden rate of 40% and 50%;the tapping method with a tapping burden rate of 40% and next day tapping was adopted for medium-age forest and a tapping burden rate of 50% and next day tapping for mature-age forest,which not only produce a higher economic benefits,but also prolong tapping resin management years. |
