摘　　要：在半干旱风沙区的山西省天镇县台地比较研究田间试验条件下保水剂、保水肥剂、济农、复绿灵等化学抗旱节水制剂对马铃薯作物的增产效应。结果表明在马铃薯开花期施用各种抗旱节水制剂,能不同程度地增加马铃薯产量,其中喷施济农和复绿灵效果最明显,值得推广。保水剂和保水肥效果不甚明显,原因是施用时间偏晚。The field experiment was carried out on dryland in semi-arid wind-sand area of Tianzhen county in Shanxi province, with the purpose of evaluating the effect of some kinds of chemical water-saving agents, such as aquasorb, water-absorbent fertilizer, Jinong and Fululing, on yields of potato(Solanum tuberosum L.). The results showed that when sprayed at flowering stage, the water saving agents could improve potato yields at different levels, and the effect of Jinong and Fululing was the most remarkable. However, the effect of aquasorb and water-absorbent fertilizer was less remarkable because the application time was late.
