华北落叶松人工林的抚育管理包括林地和林地抚育管理两个方面的内容。土壤是树木生长的基础,是水分、养分供给的基质。通过林地管理,可以使土壤有机质含量提高、土质疏松、通气透水性改善,使土壤生物活跃,土壤肥力提高,从而有利于林木根系对营养物质的吸收,有效地促进林木生长。林木的抚育管理原本是指对林木进行修枝、摘芽和除孽等,在河北坝上地区,冬季寒冷干燥,春季干旱多风,水分蒸发量大,因此,对尚未郁闭的华北落叶松人工幼林,最重要的措施是进行埋土防风,预防冬季冻拔危害和春季生理干旱。
The management of Larix principis-rupprechtii plantation includes the management of woodland and woodland management. Soil is the basis for the growth of trees and is the substrate for water and nutrients. Through forest management, soil organic matter content can be increased, soil loosening, improved aeration and water permeability, soil bioactivity, soil fertility, which is conducive to nutrient absorption of forest roots, effectively promote forest growth. Forest tending and management originally meant pruning, picking buds and removing sin. In Hebei Bashang area, the winter is cold and dry, the spring is windy and the wind is dry and windy. There is a large amount of water evaporation. Therefore, the Larix principis-rupprechtii Young forests, the most important measure is to embed the wind, to prevent the winter freeze-drawn damage and spring physiological drought.
