摘　　要：１９９４～１９９５年在隆德试区对春小麦进行了氮、磷肥效及以肥调水作用试验研究。结果表明：在干旱条件下，增施氮肥的以肥调水作用明显高于磷肥；在生产上推荐经济施肥量为：施Ｎ１０６～１４６ｋｇ／ｈｍ２、Ｐ２Ｏ５３９～５５ｋｇ／ｈｍ２。An experiment was carried out in Longde experimental area for studying the efficiency of NP fertilizer on spring wheat and their effects on bringing more water into play. The results show that under the condition of drought the effect of increasing application rates of N was significantly higher than that of P fertilizer. It is recommended that an economic application rates, namely N 106140kg/hm2 and P2O5 3955kg/hm2, should be used in production.
