首先遇到的是桉树木材单位面积产量报载广东桉林350万亩,广西150万亩,是相对地说连片的。四川五亿株,推算相当于300万亩,面积居世界上引种国家的前列,但每年实际生产木材多少?西班牙77年资料为660万亩,主要是蓝桉、赤桉,产材150万米~3,约0.227米~3/年亩,推算生长量约0.3～0.4米~3/年亩,如以12年为轮伐期算,每亩蓄积量3.6～4.8
The first encountered is the yield per unit area of eucalyptus wood coverage of 3.5 million mu of Guangxi Eucalyptus, Guangxi 1.5 million mu, is relatively contiguous. Sichuan 500 million, estimated equivalent to 3000000 acres, the area of the world’s forefront of the introduction of the country, but the actual number of wood produced each year? 77 years of data in Spain is 660 acres, mainly blue eucalyptus, red gum, production of 1.5 million meters ~ 3, about 0.227 m ~ 3 / mu, estimated growth of about 0.3 ~ 0.4 m ~ 3 / mu, 12 years if the rotation count, the volume per acre 3.6 ~ 4.8
