摘　　要：为研究河套灌区经济作物辣椒的节水灌溉制度,进行了连续两年的田间灌溉试验。根据辣椒"水涝易死秧"的特点,采用沟灌对辣椒的灌溉制度进行研究。在田间试验的基础上,利用ISAREG模型对实际灌溉制度进行了评价,并模拟了多种组合方案,得到了受黄河来水时间约束和井渠结合不受来水限制的优选方案。优化结果表明辣椒生育期内共灌水4次,总灌水量在220mm左右,产量下降率为5%左右。在不严重减产条件下水分利用率提高了12.73%。因此制定合理的灌溉制度,有利于为当地充分和有效的利用水资源提供依据。In order to do research on the irrigation scheduling for pepper in the Hetao Irrigation Area, different irrigation experiments have been performed in the last two years. According to the characteristic ＂dead seedlings＂ of pepper, furrow irrigation and the small quota methods are used to optimize. Based on the test in the fields, ISAREG is used to appraise the actual irrigation system, simulate a variety of combination plans, and obtain optimization based on the Yellow River water restriction and wells connecting canals. The results show that pepper should be irrigated four times during the period, irrigation quota is about 220 mm, production decline rate is about 5M, water efficiency increases 12.73%.
