摘　　要：为探索半干旱地区辽东栎和栓皮栎适宜的直播造林技术,笔者设置了4种不同的直播造林模式,比较了不同模式下2个树种的成活率和苗木生长量。结果表明,辽东栎和栓皮栎在有套筒和薄膜覆盖的条件下,成活率最高,生长量最大;影响半干旱地区阔叶树种直播造林生长情况的主要因子是水分、土壤温度和鼠兔危害。To explore the appropriate direct seeding afforestation technology of Quercus liaotungensis and Quercus variabilis in semi-arid areas,4 different direct seeding afforestation modes were set to compare the survival rate and seedling growth of the 2 tree species under different modes.Results showed that the survival rate and seedling growth of Quercus liaotungensis and Quercus variabilis reached the highest under the technical conditions of sleeve and plastic film covering.The main factors affecting the growth of broad-leaved trees in semi-arid areas were water,soil temperature,rat and rabbit damage.
