摘　　要：油松育苗播种时间不同,效果明显不同,适时早播,不仅能提高苗木对病虫害的抵抗力,躲过苗木出土初期的日灼,还由于延长了苗木生长期,可增强木质化程度和抗寒、抗旱性能,为安全越冬创造有利条件,并能提高单位面积优质苗产量。所以,油松育苗实行适时早播十分重要。The effect is obviously different with the different sowing time of Pinus tabulaeformis. Timely early-sowing in the proper time not only can increase the resistance of seedlings on pests and diseases, but also can avoid the sunburn during earlier unearthed seedlings. Elongation of the seedling growth stage can increase the cold and drought resistance of lignification,creating favorable condition for overwintering.
