摘　　要：以‘辽园多丽’番茄为试材,在长期定位施肥条件下研究氮磷钾与有机肥配施对产量、品质及土壤酶活性的影响。研究结果表明:氮磷钾肥配施有机肥能够提高番茄维生素C、可溶性固形物、可溶性蛋白和可溶性糖含量并且提高番茄产量;钾肥对番茄维生素C和可溶性固形物含量影响显著,磷肥对提高可溶性糖含量起着关键作用,番茄产量受氮肥影响最为显著。氮磷钾肥配施有机肥,能够提高土壤酶活性,配施氮肥能显著提高过氧化氢酶活性;磷肥对提高转化酶、蛋白酶活性具有关键作用。番茄产量、品质与土壤酶活性具有一定的正相关,土壤转化酶对番茄品质影响最多。Effects of organic manure and combined NPK fertilizers on tomato yield,nutrient contents and soil enzyme activities were systematically studied under long-term fertilization condition. Results showed that application of NPK could improve the contents of vitamin C,soluble solids,soluble protein,soluble sugar and total yield as well. Potash application resulted in significant improvement on vitamin C,soluble solids. Significant effects of phosphate and nitrogen on soluble sugar and total tomato yield were also found. Combined applications of NPK fertilizers and organic manure incented the addition of soil enzyme activities. Manure with nitrogen improved the catalase activity significantly. Phosphate played an important role on improvement of invertase and protease activities. Positive correlation between tomato yield,nutritional quality and soil enzyme activities had been found. Soil intertase activity especially contributed on tomato nutritional quality.
