1990年7月我们在保山市长岭岗定植了327亩直干桉,目的是培育6至7年便进行主伐的速生丰产造纸原料林,并合理的开展中间利用。这片直干桉总投资为57860元,平均每亩180元。定植满一年后的1991年7至8月我们进行了疏伐,并开展综合加工利用,总收入达67400元,实现了定植满一年便创收超过全部造林投资的目的。长岭岗位于保山市县城南端20公里处,海拔1650至1700米,年均温度15.5
In July 1990, we planted 327 mu of straight eucalyptus in Lingang, Mayor of Baoshan, aiming to cultivate a fast-growing and high-yield paper-making raw material forest that will be re-craned for 6 to 7 years and make rational use of it. This piece of straight eucalyptus total investment of 57,860 yuan, an average of 180 yuan per mu. From July to August 1991, one year after the planting, we carried out deforestation and carried out comprehensive processing and utilization with a total income of 67,400 yuan. The goal of planting more than the total amount of reforestation investment has been realized after one year of planting. Changling Kong is located 20 kilometers south of Baoshan county seat, elevation 1650 to 1700 meters, with an average annual temperature of 15.5
