| 摘 要： | 通过对在朝阳县十二台苗圃对沙棘种不同催芽程度后播种试验研究表明 :在催芽过程中 ,待有 70 %～ 90 %芽伸长 2～ 4mm时进行播种 ,出苗率 85 % ;90 %以上种芽伸长 5～ 10mm时播种出苗率 98% ;30 %～ 4 0 %种子裂嘴和5 0 %～ 70 %种子长出胚芽后进行播种出苗率均很低

| Abstract: | Experiment of sowing after germ accelerating in the nursery of Chaoyang County showed that when germ length of 70%～ 90% of seeds was 2～4mm, the emergence rate of seedlings was 85% ; And when germ length of 90% of seeds was 5～10mm,the emergence rate of seedlings was 98%;Sowing at the time when 30%～40% of seeds splited and 50%～70% of seeds began to extend, the emergence rate of seedlins was lower. |
