落叶松是我省主要造林树种,生长迅速,树干通直。在毛主席“绿化祖国”、“实行大地园林化”的号召,广大群众积极响应,营造了大面积落叶松人工林。目前,郁闭成林的很多,对这些林子,采取怎样的间伐方法和强度,促进林木迅速生长?在市林科所指导下,我们结合生产,探讨了这一问题。 Larch is the main afforestation species in our province, growing rapidly, trunk straight. In the call of Chairman Mao’s “greening the motherland,” and “implementing the strategy of earth gardens,” the broad masses responded positively and created large-area larch plantations. At present, there are a lot of canopy forests closed and what kind of thinning methods and intensities should be taken for these forests so as to promote the rapid growth of forest trees? Under the guidance of Linke, we have discussed this issue in combination with production.
