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.
