通过室内模拟不同土壤含水量条件下日本落叶松种子发芽出土和播种地土壤保墒措施田间试验,分析认为,日本落叶松幼苗出土阶段对土壤含水量要求严格,含水量范围应在18%～25%之间。
Through laboratory simulation of germination and dehumidification of Japanese larch seed under different soil water contents, field experiments were conducted to find that the soil moisture content of Japanese larch seedlings was demanding at the period of excavated, and the water content should be between 18% and 25% between.
