摘　　要：在滴灌施肥条件下,研究了3种滴灌专用肥对生菜产量及品质的影响。结果表明,与对照相比,腐植酸水溶性滴灌肥(T1)、叶菜类固体无机滴灌肥(T2)和通用型固体无机滴灌肥(T3)处理生菜的株高、开展度、叶片数显著提高,产量分别增加34.9%,11.8%和31.3%;3种滴灌专用肥可显著提高生菜的可溶性糖含量,有效降低其硝酸盐含量,对其维生素C含量的影响差异不显著;3种滴灌专用肥中,腐植酸水溶性滴灌肥施用效果最好,可明显促进生菜的生长,增加产量,并能有效改善生菜品质。The effects of three drip irrigation special purpose fertilizers on yield and quality of lettuce were studied. The results showed that compared to the control combining with treatment of humic acid drip irrigation fertilizer （T1）, treatment of leaf vegetables solid inorganic drip irrigation fertilizer （T2）,treatment of universal solid inorganic drip irrigation fertilizer （T3）, three drip irrigation special purpose fertilizers could significantly increase plant height, plant expansion, leaf number of lettuce. Lettuce yields were found increased 34.9%, 11.8% and 31.3% respectively. Three drip irrigation special purpose fertilizers significantly increased soluble sugar content of lettuce, decreased nitrate content, and there were no significant differences in vitamin C content. Among three drip irrigation special purpose fertilizers,humic acid drip irigation fertilizer （T1）was the best, which obviously enhanced the growth for lettuce, increased yield, improved quality of lettuce.
