摘　　要：为玉米抗旱栽培提供依据,采用室内测定、盆栽试验和田间试验相结合的方法,进行了安信、博亚和庆旺3种保水剂的保水效果及其对玉米生长与产量的影响试验。结果表明:3种保水剂的吸水、保水和再吸水能力均表现为安信>博亚>庆旺;安信和博亚保水剂能明显提高玉米出苗率,促进玉米幼苗株高、叶面积、鲜重和干重的增加,对抗旱力弱的玉米品种效果更好;在大田施用安信、博亚和庆旺保水剂的金玉1号玉米分别比不施保水剂的对照增产21.71%、15.82%和1.38%。The water-retaining effects of three water-retaining agents and their effects on growth of maize were studied by three methods of indoor determination,pot test and field test to provide the scientific basis for drought-resistant cultivation of maize.The results showed that the water absorbing capacity,water-retaining capacity and re-water absorbing capacity of three water-retaining agents are Anxin agent〉Boya agent 〉Qingwang agent,and Anxin agent and Boyaagent can improve emergence rate of maize significantly,increase height,leaf area,fresh weight and dry weight of maize seedlings,and have the better effect on maize varieties with poor drought resistance.The yield of maize applying Anxin agent,Boyaagent and Qingwang agent increases by 21.71%,15.82% and 1.38% compared with CK without applying water-retaining agent respectively.
