人工林抚育间伐,是使人工林速生丰产、调整林分密度、缩短工艺成熟期、充分发挥森林效益、增强林分抗性、提高木材利用率、促进林木生长发育的一种有效措施。如何适时进行科学的抚育间伐,是当前需要研究的课题。笔者现将红松人工林三角抚育选树法简介如下: 一、选择经验丰富,责任心强,技术熟练的挂号人员,不严格执行去小留大、去弯留直、去密留稀、去病腐留健壮的原则基础上,按五级林木进行分类。对分级后的林木,进行经验三角选树挂号,兼顾人工林抚育间伐技术规程蓄积 Thinning of plantation tending is an effective measure to make plantation fast and productive, adjust stand density, shorten process maturity, give full play to forest benefits, enhance stand resistance, improve timber utilization, and promote forest growth and development. How to carry out scientific tending at the right time is the subject that needs research at present. I now pine plantation triangle tending strategy is as follows: First, select experienced, strong sense of responsibility, skilled registered staff, not strictly enforce the small to stay big, to bend straight, to keep thin, go On the basis of the principle of surviving rotting corrupts, the trees were classified according to five grades of trees. The grading of the trees, the experience triangle selection tree registration, take into account the technical requirements of plantation tending thinning accumulation
