细叶龙竹人工林高产培育技术研究

2010年11月至2011年4月在广西、云南采用简单随机抽样法布设标准地,调查研究细叶龙竹人工林生长情况,得出其高产栽培技术措施:选择热带、南亚热带地区土层厚度40 cm以上的土山、退耕地、灌木林地、疏林地作为造林地;使用1 a生实生营养杯苗造林;幼林期每年除草1~2次,追肥2次,扩塘1次,并采伐小老竹;种植密度为630丛/hm2,每丛留养母竹6~9株.按此技术措施造林和经营,可达到1年成丛,2年成林,3年成材,采伐量达22.5~30 t/hm2,4年时采伐量达45~60 t/hm2,5年时进入高产稳产期,采伐量达75~105 t/hm2.

High-yield Cultivation Technique Research of Dendrocalamus Membranaceus Plantation

From November 2010 to April 2011, simple random sampling was adopted to lay out standard land to investigate the growth of Dendrocalamus Membranaceus plantation. High-yield cultivation technology measures were reached： select tropical, subtropical region of soil mountains, abandoned farmland, shrub land, woodland with soil thickness above 40cm as a plantation; use one year grow seedling nutrition cup seedlings to plant; weed 1 or 2 times annually on young forest, dressing two times, expanding pond once, and harvesting small old bamboo; planting density of 630 cluster/hm^2 , each cluster foster 6 to 9 mother bamboo to stay. Using these technical measures to afforestation and management, one can achieve one year to become bundle, two years to become forest, three years to become useful product with cutting capacity of 22.5 - 30 t/hm^2 , amounted to cutting 45 - 60 t/hm^2 in four years, and get into the period of high and stable yield in five years, harvest amounted to 75 - 105 t/hm^2.
