摘　　要：以‘沧麦6005’为试验材料,在旱地冬小麦春季追施水溶肥技术示范田(SR)和对照田(CK)进行调查取样,研究不同田块的产量、产量因素及肥料贡献率。结果表明:追施水溶肥技术示范田3年平均产量为5119.15 kg·hm^(-2),显著高于对照田,比对照田平均增产17.55%。增产的主要原因在于增加了穗粒数和亩穗数,穗粒数和产量间呈极显著正相关关系,相关系数为0.840;穗数和产量间呈极显著正相关,相关系数为0.666;追施水溶肥技术示范田穗粒数比CK 3年平均增加12.87%,穗数比CK 3年平均增加4.00%;追施水溶肥后肥料贡献率3年平均值为14.85%。Using‘Cangmai 6005’as the experimental material,it was investigated and taken samples in control field(CK)and demonstration field(SR)applying water-soluble fertilizer technology on winter wheat in acid land.The yield,yield factors and fertilizer contribution rate were studied.The results showed that the three-year average yield of SR was 5119.15 kg·hm^(-2),which was 17.55%significantly higher than that of CK.The grain number per spike and spike number were increased,so the yield was increased.There was a very significant correlation between grain number per spike and yield.the correlation coefficient was 0.840.There was a very significant correlation between spike number and yield.The correlation coefficient was 0.666.The three-year average grain number per spike of SR was increased by 12.87%over that of CK.The three-year average spike number of SR was increased by 4.00%over that of CK.The three-year average fertilizer contribution rate of SR was 14.85%.
