大小年毛竹林改制技术的研究是国家科技攻关项目《林木速生丰产栽培技术的研究》的一部分内部,自1984年始,研究将大小年毛竹林改制为均年(即花年)竹林,以及使均年竹林稳产经营的控制技术措施。试验中改制技术包括立竹断鞭、大年强度疏笋、改变伐竹期、自然留养小年竹等,以寻求在毛竹林中诱发小 The research on the restructuring technology of the year-old bamboo forest is a part of the national scientific and technological project “research on the fast-growing and high-yielding cultivation techniques of trees”. Since 1984, the research has changed the size of the bamboo plantation into the average annual Controlling Technical Measures for Managing Bamboo Production in a Year. In the experiment, the technology of reorganization included the bamboo breaking whip, the annual intensity of sparse bamboo shoots, the changing of the cut bamboo period, the natural retention of small annual bamboo and so on, in order to seek to induce small
