很多研究材料表明,落叶松人工林对土壤及其物理-化学性质都有良好的影响。落叶松对天然林分土壤的影响,只有ГPaдобоев[1955]进行过一些研究。1962年夏天在洛勃文森工局苏霍哥尔林场32林班(斯维尔德洛夫州)的松树-落叶松幼林地上设置了15块标准地。在其中三块最有代表性的标地上(设置
Many research materials show that larch plantations have a good effect on soil and its physico-chemical properties. The effects of larch on natural stand soil have only been studied by ГPaдобоев [1955]. In the summer of 1962, 15 standard plots were set up on pine-larch young forest land in the 32nd Lebanon (Sverdlovsk State) in the Suomenlinna field at the Lobbendon office. In the three most representative sites (set
