落叶松(Larix spp.)是东北地区速生的用材树种之一,人工造林在东北已有60多年的历史。为了进一步挖掘落叶松人工林的生长潜力,探索促进其速生丰产的途径,于1985—86年进行了日本落叶松(Larix kaempfari)人工幼林施基肥和追施化肥的试验,旨在研究落叶松人工林最适宜的营养条件,为今后大面积林地施肥提供科学依据。现将试验效果初报如下。
Larch (Larix spp.) Is one of the fast-growing timber species in northeastern China. Artificial reforestation has been in the northeast for more than 60 years. In order to further explore the growth potential of Larix kaempferi plantation and explore ways to promote its fast-growing and high yield, experiments were conducted in 1985-86 on the Larix kaempfari young plantation manure and topdressing fertilizers to study the effects of Artificial Larch The most suitable nutrient conditions of forest provide the scientific basis for the future large area forestland fertilization. Now test results are as follows.
