• Abstract: In this paper, the effects of the subsoil of Picea koraiensis and Pinus sylvestris and the mulch of litter on the growth of Ulmus pumila were studied. The results showed that the soil under the forests of Picea koraiensis and Pinus sylvestris could promote the growth of Prunus Ulmus, but had no obvious effect on the ratio of dry to fresh plants, and could be planted under the forests of both. However, the litter cover soil of Picea koraiensis inhibited the growth of Ulmus pumila to some extent. Therefore, when planting Ulmus pumila in the forest, we should pay attention to the clearing of its dead branches and leaves. 以榆叶梅盆栽幼苗为试验材料，探讨了红皮云杉和樟子松林下土、枯 枝落叶覆盖土对榆叶梅的生长的影响。结果表明：红皮云杉、樟子松的林下土 可以促进榆叶梅的生长，对植株的干鲜比无明显影响，可以在两者林下种植。 但红皮云杉的枯枝落叶覆盖土对榆叶梅的生长起一定的抑制作用。因此在其林 下种植榆叶梅时，应注意对其枯枝落叶的清理。
