摘要:

基于中国知网及Web of science核心数据库等数据库,检索2000-2024年公开发表的文献提取符合标准的春玉米产量、水分利用效率(Water use efficiencyWUE)和氮肥偏生产力Partial factor productivity of nitrogenPFPN)数据,基于Meta模型分析河套灌区沟灌和滴灌相对于畦灌在不同田间管理措施对春玉米节水增产的定量影响,以明确适合河套灌区春玉米节水增产的灌溉方式及配套的田间管理措施,为促进当地节水灌溉技术的发展,解决灌区水氮利用效率低的问题提供参考结果表明:河套灌区沟灌和滴灌对春玉米节水增产效果优于畦灌,沟灌和滴灌较畦灌春玉米分别增产12.52%11.62%WUE分别提高13.88个和33.64个百分点,PFPN分别提高12.52个和30.95个百分点。沟灌和滴灌时覆膜和合理调控种植密度显著提高春玉米产量、WUEPFPN随灌水量、施氮量增加,沟灌和滴灌对春玉米产量、WUEPFPN均为正效应,滴灌和沟灌条件下水肥协同作用强于畦灌,当灌水量<250mm或施氮量<300kg·hm−2时,滴灌处理春玉米节水增产效果最好,春玉米产量分别增加10.52%10.36%WUE分别提高10.41个和10.32个百分点,PFPN提高10.61个和10.52个百分点。综上,建议河套灌区使用膜下滴灌技术种植春玉米,种植密度≤6.5×104·hm−2、灌<250mm、施氮量<300kg·hm−2

Abstract:

Based on the database such as CNKI and Web of science core database, the literature published from 2000 to 2024 was retrieved, and the data of spring maize yield, water use efficiency (WUE) and partial factor productivity of nitrogen (PFPN) were extracted. Based on the Meta model, the quantitative effects of furrow irrigation and drip irrigation compared to border irrigation on Water saving and yield increase of spring maize were analyzed under different field management measures in the Hetao irrigation area. The aim was to clarify the irrigation methods and supporting field management measures suitable for watersaving and yieldincreasing of spring maize in the Hetao irrigation district, which would provide reference for the development of local watersaving irrigation technology and solve the problem of low water and nitrogen use efficiency in irrigation areas. Results showed that the effect of furrow irrigation and drip irrigation on water saving and yield increase for spring maize in Hetao irrigation area was better than that of border irrigation. Compared with border irrigation, the yield of spring maize increased by 12.52% and 11.62%, respectively, the WUE increased by 13.88 percentage points and 33.64 percentage points, respectively, and PFPN increased by 12.52 percentage points and 30.95 percentage points respectively under furrow irrigation and drip irrigation. Film mulching and reasonable regulation of planting density increased yield, WUE and PFPN of spring maize significantly under furrow irrigation and drip irrigation. With the increase of irrigation and nitrogen application, furrow irrigation and drip irrigation had positive effects on yield, WUE and PFPN of spring maize. The synergistic effect of water and fertilizer under drip irrigation and furrow irrigation was stronger than that under border irrigation. When the irrigation amount was less than 250mm or the nitrogen application was less than 300kg·ha1, drip irrigation had the best effect on saving water and increasing yield of spring maize, with the yield of spring maize increasing by 10.52% and 10.36%, WUE increasing by 10.41 percentage points and 10.32 percentage points , and PFPN increasing by 10.61 percentage points and 10.52 percentage points, respectively. In summary, it is recommended to use mulched drip irrigation technology for spring maize in Hetao irrigation district, with planting density not exceeding 65,000plants·ha1, irrigation amount less than 250mm, and nitrogen application less than 300kg·ha1.
