通过采取3种种子处理方式和2种覆盖措施进行辽东山区核桃播种育苗试验,结果表明,3种不同种子处理方法的出苗率大小顺序为：混沙层积催芽(86%)>圃地冷冻催芽(83.6%)>冷浸日晒催芽(73%)>对照 CK (29%)；2种覆盖方式对苗高和保存率影响显著,对地径影响差异不大。实际生产中建议采取圃地冷冻催芽方式和遮阳网覆盖方式进行核桃播种育苗。
通過採取3種種子處理方式和2種覆蓋措施進行遼東山區覈桃播種育苗試驗,結果錶明,3種不同種子處理方法的齣苗率大小順序為：混沙層積催芽(86%)>圃地冷凍催芽(83.6%)>冷浸日曬催芽(73%)>對照 CK (29%)；2種覆蓋方式對苗高和保存率影響顯著,對地徑影響差異不大。實際生產中建議採取圃地冷凍催芽方式和遮暘網覆蓋方式進行覈桃播種育苗。

Sowing and nursing experiments for Juglansregia in eastern mountains were conducted by adopting three kinds of seed treatment and two kinds of mulching measures.Result shows that the descending order of germination rate among three different seed treatments is germination with mixed sand stratification (86%)>germination under freezing in nursery (83.6%)> germination under cold-soak & solarization (73%)> CK (29% ).Two kinds of mulching methods,which have significant effects on height & preservation rate,affect little on ground diameter.It is recommended to take two treatments (freezing way in nursery and mulching with shading net)on raising seed-lings of Juglans regia.
