| 摘 要： | 目的]揭示膜下滴灌(MG)、露地滴灌(DG)、沟灌(GA)、交替隔沟灌(JG)、漫灌(CK)5种灌溉方式对春玉米生长和产量的影响,筛选出适合榆林沙区的最有效的节水灌溉方式,为农业高效节水灌溉技术发展提供理论支持。方法]基于2014年田间试验数据,运用统计分析和水分生产率计算方法。结果](1)MG处理的春玉米植株生长发育状况优于其他灌溉方式。在各生育期,MG处理的春玉米株高、茎粗和叶片SPAD值(叶绿素相对含量)均高于DG,GA和JG,且显著高于CK(p0.05);(2)在整个生育期,MG处理的春玉米叶片光合速率、气孔导度和水分利用效率均高于其他灌溉方式,且显著高于CK(p0.05);(3)MG处理的春玉米增产节水效果显著,其产量和水分生产率均显著高于其他处理(p0.05)。结论]同其他4种灌溉方式相比,膜下滴灌是榆林沙区玉米生产中最有效的一种节水灌溉方式。

| Abstract: | Objective] Through revealing the effects of drip irrigation under mulch(MG), drip irrigation without mulch(DG), furrow irrigation(GA), alternate furrow irrigation(JG) and flood irrigation(CK) on the growth and yield of spring maize, we aimed to find out the most effective irrigation method which was suitable for the sandy area of Yulin City in order to provide theoretical support for the development of agricultural water-saving irrigation technology. Methods] Based on the field experiment data in 2014, statistical analysis and calculation method of water productivity were used. Results] (1) Under the treatment of MG, the growth and development of spring maize were better than that in other irrigation methods. During whole growth period, plant height, stem diameter and leaf SPAD value in the treatment of MG were higher than that in the treatment of DG, GA and JG, and were significantly higher than that in CK(p<0.05); (2) Under the treatment of MG, the photosynthetic rate, stomatal conductance and water use efficiency of spring maize leaf were greater than the corresponding values in other irrigation methods during whole growth period, and were significantly higher than that in the treatment of CK(p<0.05); (3) Drip irrigation under mulch had significant effects on yield and water use efficiency, the two items were significantly higher than that in other treatments(p<0.05). Conclusion] Compared with other irrigation methods, the drip irrigation under mulch is the most effective irrigation method for maize in sandy area of Yulin City. |
