摘　　要：为了探讨农药与化肥不同施用量对小麦条锈病病情和产量产量的影响,采取二因素裂区设计试验。农药与化肥不同施用量,会影响小麦条锈病的发病情况,从而导致对小麦产量的影响。三唑酮施用量对产量的影响不显著,硫酸钾复合肥施用量对产量的影响极显著,其交互作用对产量的影响不显著。15个处理组合的小麦产量差异极显著,可能是由于硫酸钾复合肥的施用量对小麦产量影响差异的极显著所致。在毕节市小麦//绿肥+玉米分带轮作的耕作制度下,以1.65 m分带的种植,小麦播幅保证0.5 m,按基本苗120万株/hm^(2)安排小麦播种量,采取精量施肥,施用硫酸钾复合肥180 kg/hm^(2)作基肥最佳;在小麦条锈病发病初期,以1050 g/hm^(2)的剂量,采用大功率喷雾器,选准晴好的天气均匀喷施最好。The aim of this study was to investigate the effects of different application rates of pesticides and fertilizers on wheat stripe rustand yield.two-factor split-zone design was used.different application rates of pesticides and chemical fertilizers would affect the incidence of wheat stripe rust,which would lead to the impact on wheat yield.Triadimefon had no significant effect on yield,potassium sulfate had significant effect on yield,and its interaction had no significant effect on yield.The significant difference of wheat yield among 15 treatment combinations may be due to the significant difference of the effect of potassium sulfate compound fertilizer on wheat yield.under the wheat-green manure-maize zonal rotation system in Bijie,the sowing width of wheat is guaranteed to be 0.5 m under the 1.65 m zonal cropping system,and the sowing amount of wheat is arranged according to the basic seedling of 1.2 million plants/hm^(2),in the early stage of wheat stripe rust,the best basal fertilizer is 180 kg/hm^(2) of potassium sulfate compound fertilizer,and the best one is 1050 g/hm^(2) of high-power Sprayer in fine weather.
