研究高产脂力树种,对发展松脂生产具有重大意义,为此我们对高产树的树脂道进行了研究。根据松树一般产脂规律,在同一树种或同一品系中,胸径愈大,产脂量愈高,相反则低。但是,在尤溪县新桥公社葛竹大队后山化学采脂马尼松试验林地内,同一坡面,同一立地条件,同一种属的松树,相隔距离不到5—6米,同样采用化采,但采脂量相 Studying high yielding tree species is of great importance to the development of rosin production. Therefore, we studied the resin path of high yield tree. According to the general law of fat pine production, in the same species or the same strain, the greater the diameter of the breast, the fat yield higher, on the contrary is low. However, in Youxi County, Xinqiao Commune Ge Zhu Brigade Hill Chemical Test fattening Pinus massoniana forest, the same slope, the same site conditions, the same genus of pine, separated by less than 5-6 meters, the same use of Mining, but picking fat phase
