摘　　要：为了探索不同种类钾肥配施对烤烟钾积累、烟叶产量和质量的影响,选用烤烟品种云烟87为试验材料,在重庆市巫溪县古路镇青龙村开展了不同硫酸钾和黄腐酸钾配施方案的田间比较试验。结果表明:T2处理(70%硫酸钾和30%黄腐酸钾)的烟株田间长势最好,T3处理(50%硫酸钾和50%黄腐酸钾)次之;T3处理的烟株干物质积累量最多、根体积最大;T2处理能提高土壤速效钾含量,并减少土壤缓效钾的消耗,更利于植物吸收利用钾离子;T3处理烟叶的钾分配系数最大、钾肥表观利用率较高且烟叶的化学成分含量及其协调性较适宜,T5处理(100%黄腐酸钾)烟叶的钾积累量最大,钾肥表观利用率最高,T2处理烤后烟叶的化学成分含量及其协调性最适宜;T3处理的产量最高,达107.21 kg/667m^(2),T5处理的产值最高,达1526.87元/667m^(2)。综合考虑烟株的长势、干物质积累、根体积、钾素利用率、烤后烟叶的化学成分及其协调性、产量和产值等因素,T3处理(50%硫酸钾和50%黄腐酸钾)是钾肥配施的最优方案,可在当地生产上推广应用。In order to explore the effects of different potassium fertilizers on potassium accumulation,yield and quality of flue-cured tobacco,a field comparison experiment of the combined schedules of potassium sulfate and potassium fulvic acid was conducted in Qinglong Village,Gulu Town,Wuxi County,Chongqing,by using Yunyan 87 as the tested material.The results showed that:T2(70%potassium sulfate+30%potassium fulvic acid)had the best growth of field plants,followed by T3(50%potassium sulfate+50%potassium fulvic acid);T3 had the largest dry matter accumulation and root volume;T2 increased the content of soil available potassium and reduced the consumption of soil slow-release available potassium,which was more conducive to the absorption and utilization of potassium ions by plants;T3 had the largest potassium distribution coefficient of tobacco leaves,a higher apparent use efficiency of potassium fertilizer,and appropriate chemical composition and harmony of tobacco leaves;T5(100%potassium fulvic acid)had the highest potassium accumulation and potassium apparent use efficiency;T2 had the most coordinated chemical components and optimal harmony;T3 had the highest yield,reaching 1608.15 kg/hm^(2);T5 had the highest output value of 22903.05 yuan/hm^(2).Considered from the aspects of tobacco growth,dry matter accumulation,root volume,potassium use efficiency,chemical composition and harmony,yield and output value,T3 is the best choice for the combined application of different potassium fertilizers,which could be promoted in tobacco production.
