| 摘要: |
| 【目的】评估水肥调控对马铃薯产量、水分利用效率（WUE）和肥料偏生产率（PFP）的影响。【方法】采用数据整合（Meta）分析，以马铃薯产量和水肥利用效率为决策因子，筛选获得目标文献29篇，建立水-肥-产量（440组）、水-肥-WUE（318组）、水-肥-PFP（428组）共计1 186组观测值的数据库。分析水肥调控对西北地区马铃薯产量和水肥利用效率的影响，优选西北地区马铃薯最优水肥调控区间。【结果】对宁夏马铃薯生产而言，适量增加灌水量和施肥量至最佳水肥调控区间可增产14.12 t/hm2，增加2.96 kg/m3的WUE和32.83 kg/kg的PFP；对甘肃马铃薯生产而言，降低施肥量至最佳施肥区间可增加27.58 kg/kg的PFP；对内蒙古马铃薯生产而言，降低灌水量并增加施肥量至最佳水肥调控区间，可增产17.92 t/hm2，同时增加3.33 kg/m3的WUE和30.91 kg/kg的PFP。【结论】西北四省（自治区）马铃薯最优水肥调控区间分别为：宁夏（灌水量900~2 100 m3/hm2，施肥量345~531.6 kg/hm2）、甘肃（灌水量2 895~3 550 m3/hm2，施肥量420~630 kg/hm2）、陕西（灌水量1 650~2 940 m3/hm2，施肥量415~630 kg/hm2）、内蒙古（灌水量1 350~2 070 m3/hm2，施肥量435~675 kg/hm2）。本研究结果可为制定西北地区马铃薯高产高效的水肥管理策略提供参考。 |

| Abstract: |
| 【Background and Objective】Northwestern China is the national hub of potato production, with irrigation and fertilization being the key factors affecting the yield, water and fertilizer use efficiency of the potato. The objective of the paper is to systematically assess the effect of different irrigations and fertilizations on yield, water use efficiency (WUE) and fertilizer partial factor productivity (PFP) of the potato in this region. The yield and water and fertilizer use efficiencies of the potato were treated as the decision factors for deriving the optimal irrigation and fertilization.【Method】The study was based on meta-analysis and extensive literature review using the data obtained from 29 sources. A dataset was established, which comprised 440 observations for water-fertilizer-yield relationship, 318 for water-fertilizer-WUE, and 428 for water-fertilizer-PFP. The analysis focused on the impact of water-fertilizer management on yield and efficiency metrics of the potato for Ningxia, Gansu, Shaanxi and Inner Mongolia in the northwestern China.【Result】In Ningxia, moderately increasing the irrigation amount and fertilization to optimal water-fertilizer levels can increase the maximum potato yield to 14.12 t/hm2, the WUE to 2.96 kg/m3 and the PFP to 32.83 kg/kg. In Gansu, reducing fertilization to the optimal level can increase the maximum PFP to 27.58 kg/kg. In Inner Mongolia, reducing irrigation and increasing fertilization to optimal levels can increase the maximum potato yield to 17.92 t/hm2, the WUE to 3.33 kg/m3 and the PFP to 30.91 kg/kg.【Conclusion】The optimal irrigation and fertilization for potato production in the four provinces in the northwestern China are: 900-2 100 m3/hm2 of irrigation and 345-532 kg/hm2 of fertilization for Ningxia, 2 895-3 550 m3/hm2 of irrigation and 420-630 kg/hm2 of fertilization for Gansu; 1 650-2 940 m3/hm2 of irrigation and 415-630 kg/hm2 of fertilization for Shaanxi; 1 350-2 070 m3/hm2 of irrigation and 435-675 kg/hm2 of fertilization for Inner Mongolia. These can be used as guidelines for potato production in these regions. |
