摘　　要：2012年对晋南3个县174个农户水地冬小麦灌溉施肥效果进行了调查研究。结果表明,该地区农户水地冬小麦产量较高,平均为5 836.7 kg/hm2,增产潜力较大;平均灌溉次数由1.9次增加到2.3次时,水地冬小麦产量会增加;当地施肥状况极不平衡,氮肥用量偏高,而磷肥不足;在当年降雨较为充足的情况下,当氮肥用量为180 kg/hm2、磷肥用量为100 kg/hm2左右时,水地冬小麦产量达到最高。适量增加灌水次数、控制氮肥用量、增加磷素养分投入对水地冬小麦增产有重要意义。174 samples were investigated and effects of irrigation and fertilization to yield were analyzed in south of Shanxi province in 2012. The result showed： The yield of the irrigation-land winter wheat was high in the region. The average yield was 5 836.7 kg/hm2 and productive potentialities great. When the frequency of irrigation from 1.9 times increased to 2.3, the grain yield of winter wheat in- creased. The fertilization condition was unbalanced in the region, the application of N fertilizer is high but P fertilizer insufficient. In the year of adequate rainfall, when the N fertilizer application was about 180 kg/hm2 and P fertilizer about 100 kg/hm2, the grain yield of win- ter wheat was the highest. Therefore, increasing the frequency of irrigation, suitable application of fertilizers and increasing P nutrient in- puts properly is of significant importance to improve the grain yield of irrigation-land winter wheat yield.
