摘　　要：以"汉诺威"番茄为试材,通过测定番茄叶片叶绿素含量、果实纵横径、畸形果率、单果质量、果实可溶性固形物、维生素C含量、产量及产值,研究了喷施硫酸钾、氯化钾、磷酸二氢钾等叶面钾肥对日光温室番茄产量、品质和效益的影响。结果表明:喷施硫酸钾、氯化钾、磷酸二氢钾均显著提高了番茄植株叶片的叶绿素含量、番茄果实单果质量、果实可溶性固形物、维生素C含量,降低了番茄果实的畸形果率,且叶面肥磷酸二氢钾的处理效果最佳。喷施硫酸钾、氯化钾、磷酸二氢钾每667m2产量较对照分别提高了140.77、295.06、362.81kg。总之,喷施叶面钾肥显著提高了番茄果实单位面积产量,改善了果实品质,且磷酸二氢钾在增收方面优于其它类型叶面钾肥。The tomato variety ‘Hannuowei＇was used as test material.The chlorophyll content of leaves,fruit height and diameter,malformed berry ratio,fruit weight,yield,production value and profit were measured to test the effect of different potash fertilizers on yield,quality and profit of tomato.The results showed that spraying foliar fertilizer,potassium sulphate,potassium chloride and potassium dihydrogen phosphate all improved the chlorophyll content of leaves,fruit weight,the soluble solid content,vitamin C content as compared with control,while decreased the malformed berry ratio,and the effects of spraying potassium dihydrogen phosphate was better than another foliar fertilizer treatment.The 667 m2 yields of spraying potassium sulphate,potassium chloride and potassium dihydrogen phosphate were increased by 140.77 kg,295.06 kg and 362.81 kg,respectively,and also improved the profit.It indicated that spraying foliar fertilizer could improve the yields and quality of tomato,the effect of spraying potassium dihydrogen phosphate was the best.
