摘要
采用V字形下降法对枫香树进行采脂试验研究,主要考察了采脂季节、枫香树胸径、树龄、采割高度、割沟频率等因素对产脂量的影响。结果表明,7、8、9三个月为产脂量较高月份;30 cm以上胸径的树产脂量更高;树皮黑色、有裂纹、30年以上的枫香树产指率更高;第一对割沟高度在1.5 m的树产脂量更高;15天割一次沟的产脂量更高等。采用V字形下降法进行枫香树采脂是可行的。
V-shaped descent method was used in the resin of Liquidambar ( an oleoresin or a resin) tapping from Chinese sweet gum(Liquidambarfromosana trees). The studies were mainly on the influence of the resin yield by these factors, such as the resin tapping season, diameter at breast height (DBH) of Chinese Sweet Gum, age, streak height and streak frequency etc. The results showed that the higher resin yield occurred in July, August and September; the resin yields of Chinese Sweet Gum with DBH above 30 cm were higher; and the resin yields of Chinese Sweet Gum over 30 years with black bark and cracks were higher; the resin yields of Chinese Sweet Gum with first pair of streak at 1.5 m were higher; and the resin yields of Chinese Sweet Gum being cut every 15 days were higher. Using V-shaped descent method for Chi- nese sweet gum tapping was feasible.
