| 摘 要： | 目的]为宁夏引黄灌区滴灌灌溉制度的确定提供依据.方法]在2012年,采用对比试验,分析了宁夏引黄灌区典型区域内不同灌溉制度对冬小麦与玉米作物产量及其生育性状的影响.结果]滴灌可以有效提高冬小麦对水分和养分的吸收.冬小麦、玉米产量和株高随着灌溉量和灌溉次数的增多而增大.与常规灌溉相比,滴灌水肥一体化冬小麦产量和千粒重分别增加14.0％和11.64％,灌溉量和施肥量分别减少63.2％、55.1％.滴灌灌溉下玉米平均产量、平均千粒重分别比对照高35.10％和17.42％,且前者的灌溉量和施肥量分别比后者减少55.5％、50.1％.结论]在宁夏引黄灌区实施滴灌灌溉冬小麦、玉米时,可以分别采用灌溉量190和200 m3/hm2为其参考编制灌溉、施肥制度.

| Abstract: | Objective] The research aimed to provide the basis for the determination of the drip irrigation schedule in Ningxia Yellow River irrigation district.Method] The contrast test was carried out to analyze the effects of the different drip irrigation schedule on the yield and growth characters of winter wheat and corn in Ningxia Yellow River irrigation district.Result] The drip irrigation increased the absorptive capability of the winter wheat on the water and nutrition.The yield and plant height of winter wheat and corn were increased with the increasing irrigation and irrigated times.In comparison with the flood irrigation,the yield and thousand kernel weight of winter wheat with the drip fertigation were more than 14.0% and 11.64%,respectively,and the irrigation amount and fertilizer amount were lower than 63.2% and 55.1%,respectively.The yield and thousand kernel weight of corn with the drip fertigation were more than 35.10% and 17.42%,respectively,and the irrigation amount and fertilizer amount were lower than 55.5% and 50.1%,respectively.Conclusion]190 and 200 m3/hm2 should be taken as the reference to make the irrigation program of the winter wheat and corn respectively in Yellow River irrigation district. |
