摘　　要：为了探讨不同氮、磷、钾肥施用处理对冬小麦生长发育和产量的影响,在垣曲县永兴村进行了的冬小麦田间试验。结果显示,全肥处理显著提高了冬小麦的株高、穗数、穗粒数和千粒质量,理论产量最高。相比之下,缺氮处理对小麦生长的负面影响最大,显著降低了小麦产量和养分吸收量;无磷和无钾处理也影响了小麦的生长和产量,但影响程度较小。In order to investigate the effects of different N,P and K application treatments on the growth and yield of winter wheat,a winter wheat field experiment was conducted in Yongxing Village of Yuanqu County.The results showed that the total fertilizer treatment significantly increased the plant height,panicle number,kernel number per spike and thousand grain mass of winter wheat,and the theoretical yield was the highest.In contrast,nitrogen deficiency treatment had the greatest negative effect on wheat growth,significantly reducing wheat yield and nutrient uptake.Phosphorus-free and potassium-free treatments also affected the growth and yield of wheat,but to a lesser extent.
