摘　　要：辽西地区干旱少雨、土壤保水能力差、水分利用效率低,这些一直是制约当地玉米增产的关键因素。通过对比试验的方法,研究抗旱保水剂和肥料混合施用与常规施肥两种条件下,对玉米生育性状及产量的影响。试验结果表明,应用抗旱保水剂的玉米生育性状好于常规施肥,株高增加6~16.4 cm、茎粗增加0.28~1.3 cm、穗粒数增加42~54个、百粒质量增加1.05~1.7 g,增产87.8~121.55 kg/667 m^(2)、增产率为10.2%~17.29%。Drought and low rainfall,poor soil water retention capacity and low water use efficiency have been the key factors restricting the yield increase of maize in western Liaoning.The effects of mixed application of drought-resistant water-retaining agent and fertilizer and conventional fertilization on maize growth character and yield were studied by comparative experiment.The test results showed that the growth characteristics of maize with drought-resistant water-retaining agent was better than that with conventional fertilization,with plant height increased by 6.0~16.4 cm,stem diameter increased by 0.28~1.30 cm,grain number per spike increased by 42~54,grain mass per 100 increased by 1.05~1.70 g,and yield increased by 87.80~121.55 kg/667 m^(2),and yield increased from 10.20%to 17.29%.
