迹地更新的初植密度,不仅影响林木营养面积、光能利用及生长质量,而且直接关系经营森林的效益.如何确定合理的初植密度,一直是营林工作者讨论的重要课题.本文从总结历史经验入手,立足森林的总体经营谈几点认识. 回顾黑龙江省更新造林历史,在五十年代,曾推广苏联经验,流行过每公顷初植密度6,000株的大密度更新造林.主张大密度造林的前提是全面皆伐、全面人工更新,其理由是幼林可以提前郁闭,既能解决地广人稀 The newly planted planting density not only affects the nutrition area, light energy utilization and growth quality of forest, but also directly affects the benefit of forest management.How to determine the reasonable initial planting density has always been an important issue for forest managers to discuss. Historical Experiences, based on the overall management of the forest to talk about the general point of view.Review of the history of reforestation in Heilongjiang Province, in the fifties, had promoted the Soviet experience, prevalence of initial planting density of 6,000 plants per hectare of high density reforestation advocate large density afforestation The premise is a comprehensive clear-cut, a comprehensive manual update, the reason is that young forests can be closed in advance, both to solve the sparsely populated
