摘　　要：2001—2004年连续4年在大田和池栽2种条件下研究主要栽培措施（氮磷钾、灌水和喷洒杀菌剂）对强筋小麦产量和品质的影响。研究结果表明，氮肥运筹以“前轻中重后补充”模式的产量品质俱佳；施用氮肥对强筋小麦的面团稳定时间有明显的正效应，对蛋白质、湿面筋有一定的正效应，尤其在肥力偏低的地块，施氮效果十分明显，而磷、钾肥对几项指标都有一定负效应；强筋小麦的品质指标有随灌水次数的增加而降低的趋势，产量和品质俱佳又节水的处理为小麦生育中期供水即浇拔节期水；喷洒杀菌剂可以显著提高子粒千粒重，喷洒1次杀菌剂对子粒品质无明显影响，喷洒3次子粒的品质有下降的趋势。The influences on yield and quality of major cultural techniques in hard wheat were studied by field experiment for 4 years. The results showed that the model of n fertilizer for Hard Wheat, higher in jointing than in seedtime and spike-time, was beneficial for high yield as well as quality. N fertilizer elevated prominently stability time and protein as well as wet gluten, especially in field of lower soil fertilizer. On the other way, P and K fertilizer reduced them. The quality of hard wheat was elevated with the number of irrigation. Optimal irrigation model was just jointing water of whole grows stages. Praying germicides elevated distinctively 1000-grains weight, and quality of grain was not influenced when spraying bactericide 1 time in flowering stage, but reduced when spraying bactericide 3 times in heading and flowering and grain-filling stage.
