在毛主席“绿化祖国”的方针指引下,我场自1953年以来营造油松幼林2万亩。为促使幼林快速生长,尽快给国家建设提供更多的木材,20年来,我们在幼林管理方面摸索到一点经验,供大家参考。 我们对幼林的管理,主要是适时修枝和间伐。从造林后第二年起,我们对油松幼林连续进行2—3年松土除草工作,到幼林接近郁闭时,进行第一次修枝。双株栽植的在修枝前或修枝时进行一次定株。在第二次修枝后,幼林开始郁闭,林木开始分化,高生长加快,粗生
Guided by Chairman Mao’s principle of “greening the motherland,” we have created 20000 mu of young pine forests in our field since 1953. In order to promote the rapid growth of young forests and provide more timber to the national construction as soon as possible, we have found some experience in the management of young forests for reference for the past 20 years. Our management of young forests is mainly timely pruning and thinning. From the second year after afforestation, we conducted 2-3 years of continuous weeding on young weeds of Pinus tabulaeformis, and the first pruning was conducted when the young forest was close to the canopy. Double plantation in the pruning or pruning before a given strain. After the second pruning, the young forest began to be closed and the trees started to differentiate, the height of the soil increased,
