摘　　要：试验选择玉米为指示作物,采用小区试验和大田对比试验相结合的方法,研究几种保水剂对干旱气候条件下玉米产量性状和产量的影响。小区试验结果表明,浙江建德“绿洲”超强保水剂增产效果极显著(F=21.83),使玉米增产9.73%。大田对比试验结果表明,保定“科翰98”高效抗旱保水剂增产效果最佳,使玉米增产25.9%～26.3%。Plot and field experiments were conducted to study the effects of super absorbent polymer on yield as well as its constituent factors of corn in arid area in west Heilongjiang. Plot experiment results showed that the super absorbent polymer of ＂Oasis＂ brand produced in Jiande, Zhejiang Province increased corn yield significantly, corn yield was increased by 9.73%; field experiment results indicated that the super absorbent polymer named ＂Kehan 98＂ increased corn yield by 25.9%-26.3%.
