摘　　要：通过田间溶解试验,研究了金叶、三宁、宜化、撒可富4种复合肥的养分释放规律及其对白肋烟生长的影响。结果表明,4种复合肥的养分均为钾、氮释放较快,磷释放较慢,施肥后80 d,氮素残留率为2.0%~3.8%,钾素残留率为2.8%~4.4%,磷素残留率为17.8%~21.3%;不同复合肥溶解速率从快到慢排序为三宁复合肥>撒可富复合肥>宜化复合肥>金叶复合肥;金叶复合肥处理的株高显著低于其他处理,宜化复合肥处理株高最高,各处理茎围、叶片数、最大叶长、最大叶宽之间差异均不显著。不同复合肥释放能力越强,释放速率越快,烟叶产量、产值越高,金叶复合肥中氮、磷、钾养分释放速率均低于其他处理,施用后烟叶田间长势及产量、产值均显著低于其他处理,在实际烟叶生产中不宜使用。The nutrient release rules of Jinye,Sanning,Yihua and Sakefu fertilizers and their effects on the growth of Burley tobacco were studied by field dissolution experiments.The results showed that the nutrient release rate of K and N of four kinds of compound fertilizers was faster than that of phosphorus.80 d after fertilization,the residual amount of nitrogen was 2.0%-3.8%,that of potassium was 2.8%-4.4%,and that of phosphorus was 17.8%-21.3%.The order of dissolution rate of different compound fertilizers was Sanning compound fertilizer>Sakefu compound fertilizer>Yihua compound fertilizer>Jinye compound fertilizer.The plant height of Jinye compound fertilizer treatment was significantly lower than that of other treatments,and the plant height of Yihua compound fertilizer treatment was the highest.There was no significant difference in stem circumference,leaf number,maximum leaf length and width among the treatments.The release rate of nitrogen,phosphorus and potassium in Jinye compound fertilizer was lower than that of other treatments,the growth and output value of tobacco leaves after application were significantly lower than those of other treatments.Therefore,Jinye compound fertilizer is not suitable to use in actual tobacco production.
