摘　　要：本试验对核桃种子采用秋季和春季播种,处理方式为温水(40℃~45℃)、常温水浸种、沙藏和不处理4种方法进行对比试验研究。结果显示:在秋季播种,且采用沙藏和常温水处理对核桃种子发芽率和种苗的生长均显著优于其他处理,秋播常温水处理,核桃种子的发芽率最高,达93.98%,出苗时间50 d左右。说明在攀枝花地区核桃育苗要随采随播,且采用秋播常温水和沙藏催芽方法为最佳。In this experiment, walnut seeds included the four methods such as soaking were sown in autumn and spring. And the seed treatment ways with warm water （40℃ -45℃ ）, soaking with room tempera- ture water, sand storage, and untreatment, aiming to conduct the germination contrast experimental study. The results showed that in the autumn sowing and by use of sand storage and room temperature water treatment, the germination rate and seedling growth of walnut seeds were significantly better than those by use of other treatments, and the wanut seed had the highest germination rate by use of room temperature water treatmut reaching 93.98%, and the seedling emergence time necded about 50 days. So, the walnut breeding in Panzhihua shoud adopt a timely manner, and the autumn sowing, the use of room temperature water and sand storage method showd be the best.
