丘陵区过去营造杉木林,有的适地适树注意不够,加之整地粗放或抚育不及时,管理不善,往往容易形成“小老头”。主要表现是衰老、平顶、弯曲、萌芽丛生,生长缓慢。这些看来没有发展前途的杉林,应该通过改变环境条件,加以改造。近几年来,我地广大群众在生产实践中,发挥人的主观能动作用,大搞杉木“小老头”改造试验,采取不同措施,取得了显著效果。深挖抚育:由于整地不深,抚育不及时,形成“小老头”林,应清除杂草,深挖抚育,挖掉多年盘结的草根。这样可促 Hilly areas in the past to create fir forest, and some suitable trees not enough attention, together with extensive or improper preparation tending, poor management, often easy to form “little old man.” The main performance is aging, flat-topped, curved, germination, slow growth. These seemingly no prospects for the fir forest, should be changed by changing the environmental conditions, to be transformed. In recent years, the vast majority of the people in our region have given play to their subjective and active role in their practice of production. They have also engaged in the experiment of “small old man” renovation of Cunningham and taken different measures and achieved remarkable results. Deepen tending: As soil preparation is not deep, tending is not timely, the formation of “old man” forest, weeds should be removed, digging up and tearing down the roots of many years of ending. This can promote
