摘  要：
为了寻求一种适合相关地区膜上灌玉米的水肥组合方案,在宁夏引黄灌区进行了为期2年的试验,并保证2年试验方案完全相同。为避免只考虑产量这一单一因素便评价的不足之处,选择了典型性状和与产量构成密切相关的8个指标进行分析,经新复极差检验法检验,在选定的因素中,不同水肥处理间秸秆充实度和穗粒数差异显著,其余因素不显著;采用层次分析法确定各因素的权重,用多因素模糊综合评判法对其进行评价,得出了适合当地条件的水肥组合方案,即为整个生育期灌水2次,每次定额为1200 m3/hm2,纯氮和纯磷的比值为2.5。这一结论也可供条件相似地区参考。

摘  要：
In order to seek a suitable combination between water and fertilizer for the maize irrigated from the film hole in some region, the trial was carried out for two years in Ningxia irrigation district diverting water from Huang River, and was ensured that the scheme was equal in two years. Avoiding a shortage of only think about one index-yield, eight important indexes were selected and analyzed in the trial, results showed that substantial degree of stalk and quantity of grain of corn ear among different disposals reached a level of significance of difference, and the other indexes were not significant difference by range analysis; and the suitable combination between water and fertilizer in trial region was gained by analytical hierarchy process and multi-factor fuzzy comprehensive evaluation. The combination was that maize should be irrigated twice during the whole growing period, and the water quantity was 1200 cubic metre per hectare every time, and the ratio of quantity of nitrogen and phosphor was 2.5. Further more, the conclusion can be referenced in similar region.
