龙脑型樟树在平远县推广效益分析
|
摘要
利用广东省林业科学研究院选育的的龙脑樟优良品系在广东平远县进行推广应用,根据对营建的平远县石正镇的龙脑樟推广示范林调查数据进行分析,结果显示龙脑樟林长势良好,种植后4a,林木保存率达91.2%,平均高2.75m、平均地径5.30cm、平均冠幅1.52m、平均单株采收枝叶11.75kg;经过实际调查与评估,第4年起可通过销售枝叶获得利润,项目净现值为1735.34元(折现率为0.05的情况下),内部收益率为25.54%、投资利润率为16.59%,静态投资回收期为3.94a、动态投资回收期为4.07a。分析结果说明龙脑樟种植业可取得较好的经济效益,因此建议平远县依托当地的龙头加工企业大力发展龙脑樟种植业,促进地方经济发展。
uperior strains of Cinnamomum camphora chvar. Borneol selected by Guangdong Acadamy of Forestry was introduced to Pinyuan county. Analysis on the investigation data of the popularizing demonstration forest planted in Shizhen town, results show that stand was growing well, when stand is in 3 age forest,its survival rate was 91.2%,average height of stand was 2.75 m,average ground diameter was 5.30 cm,and average crown was 1.37 m,average weight of branches and leaves harvested was 11.75kg/s. Evaluation on the basis of actual surve, profit was obtained by selling branches and leaves after planted 4 years,NVP of projest is $1735.34(discount rate is 0.05),IRR is 25.54%,investment profit rate can reach 16.59%,and the recovery period of investment is about 4 years. The analysis results show that the planting industry of d-borneol type of Cinnamomum camphora can obtain better economic benefits. So We suggest that the goverment of Pingyuan County shall rely on local leading enterprises to develop planting industry of d-borneol type of Cinnamomum camphora vigorously,and promote the development of local economy.
