摘　　要：研究了不同保水剂及用量对刺槐种子发芽及成苗的影响。结果表明,采用适宜用量的保水剂在刺槐播种前进行包衣处理,降低刺槐种子发芽指数,对发芽率影响不大,两种保水剂可以提高种子成苗率、苗高、苗粗。保水剂与种子质量比为1︰4处理的种子成苗率、苗高、苗粗的数值较大。The effects of two kinds Super-Absorbent-Polymers on seed germination and seedling growth of black locust (Robinia Pseudoacacia L.) were compared. The results showed that two kinds Super – Absorbent -Polymers could reduce seed germination index, meanwhile , had no effect on germination rate. Both kinds Super –Absorbent -Polymer could increase seedling growth rate, seedling height and seedling thick under drought-resistant. The best rate of Super –Absorbent -Polymer to seed was 1︰4.
