中文摘要	【目的】为合理制定主食化专用品种宁薯16号在宁夏中部干旱带适宜的灌溉制度,为其大面积推广种植提供灌水依据。【方法】本试验采用水量单因素试验,设置5个梯度灌溉定额处理。【结果】灌水量和株高表现为正相关关系,6月29日测定株高,处理5最大,为56.8 cm。马铃薯在现蕾期处理1较处理5根系生物量多66.7 %,但地上部生物量处理5较处理1多97.4 %,但在8月20日,处理4较处理5的地上生物量多7.4 %。产量和商品薯率最高均为处理4,分别为3279.4 kg/667m~2和80.41 %,水分利用效率WUE处理1最大,为11.81 kg/m~3, 较最小值处理5高29.7 %。马铃薯品质随着灌水量增加,各指标表现为先增加后减小的趋势,灌溉定额小于4500 m~3/hm~2时,淀粉、蛋白质和多糖等指标的含量较大。综合以上各因素,为实现水资源高效利用, 【结论】宁夏中北部干旱地区推荐处理3(灌溉定额为4500 m~3/hm~2)作为马铃薯主食化专用品种宁薯16号的灌溉定额。
英文摘要	【Objective】The present study aimed to rationally formulate a suitable irrigation system for the special diet of Ningxia No. 16 in the central arid zone of Ningxia and provide a basis for irrigation for large-scale planting.【Method】In this test,a single factor test of water volume was used,and five gradient irrigation quotas were set. 【Result】The irrigation amount and plant height showed a positive correlation. The plant height 5 was the highest in the plant height measured on June 29,which was 56.8 cm,which was 24.5 % larger than the minimum treatment. The treatment of potato in the bud stage was 66.7 % larger than that of the treated 5 roots,but the aboveground biomass treatment 5 was 97.4 % larger than the treatment 1 but on August 20,the treatment 4 was 7.4 % larger than the aboveground biomass. The highest yield and commercial potato rate were treated 4,3279.4 kg/667m~2 and 80.41 %,respectively. The water use efficiency WUE treatment 1 was the largest,11.81 kg/m~3, which was 29.7 % higher than that of the minimum treatment. The quality of potato increased with the increase of irrigation amount,and the indicators showed a trend of increasing first and then decreasing. When the irrigation quota was less than 4500 m~3/hm~2, the content of starch,protein and polysaccharide was larger. 【Conclusion】Based on the above factors,in order to achieve efficient use of water resources,it is recommended to treat 3 (irrigation quota of 4500 m~3/hm~2) in the arid regions of central and northern Ningxia as the irrigation quota for the special potato variety Ningshu No. 16.
