| 摘 要： | 为提高旱作麦区集蓄雨水的转化利用，以深层防堵渗灌系统和旱地小麦‘运旱618’为试验材料，研究了2012—2017年5个小麦季限量补水渗灌对冬小麦产量及产量结构、补水渗灌水分利用效率和经济效益。结果表明，补水渗灌处理比对照增产47.5%~478.0%，补水渗灌处理的穗数、穗粒数、千粒重都显著高于对照；不同年型补水渗灌处理的耗水量都大于对照，水分利用率较对照提高2.6~8.1 kg/(hm2?mm)，提高了15.0%~245.5%，灌溉效率5.7~9.4 kg/(hm2?mm)，干旱年型水分利用率、灌溉效率提高幅度最大。以5年平均产量和小麦价格2.36元/kg计算，补水渗灌纯收益6849元/hm2，比对照提高117.4%。深层防堵渗灌系统在旱地小麦上节水增产增效效果显著。

Deep Anti-Blocking Infiltration Irrigation for Dry Land Wheat |
| |
| Abstract: | The paper aims to improve the rain-collected water use efficiency on dry land wheat. Taking deep anti-blocking infiltration irrigation system and dry land wheat ‘Yunhan 618’ as test materials, the authors studied the effects of 5 limited water supplement irrigation on yield and yield component, water use efficiency and economic benefit of winter wheat in 2012-2017. The results showed that: water supplement irrigation increased the yield by 47.5%-478.0%, spikes, kernels/spike and 1000-grain weight significantly increased compared with the control, respectively; the water consumption in infiltration irrigation were greater than that of the control, the water use efficiency increased by 2.6-8.1 kg/(hm2?mm) compared with control and by 15.0%-245.5%, and the irrigation efficiency were 5.7-9.4 kg/(hm2?mm) in different precipitation years; the increase range of water use efficiency and irrigation efficiency were the greatest in drought years. The pure income of infiltration irrigation was 6849 yuan/hm2, and 117.4% higher than that of control based on 5-year average yield and 2.36 yuan/kg of wheat price. Deep anti-blocking infiltration irrigation system had remarkable effects on water-saving and yield increase and economic benefit. |
