摘要：为了探索水肥耦合在设施番茄上的应用效果及其对肥料减施的贡献，采用田间试验，设置6 个处理，研究了水肥耦合条件下底肥减施20%和40%、灌溉量减少15%的条件下对设施番茄产量、品质和土壤养分的影响。结果表明：中水中肥（W2F2）处理产量最高，显著高于其他处理，产量比高水中肥（W1F2）处理提高2.0%，比常规处理（W1F1）提高4.1%。中水中肥处理番茄可溶性固形物、维生素 C、土壤有机质、碱解氮、有效磷、速效钾含量比常规处理分别提高1.5%、5.8%、6.5%、6.3%、4.5%、 10.6%。说明中水中肥处理（80%常规施肥＋滴灌至田间持水量的85%，每公顷每次施用51 kg大量元素水溶肥随水滴灌4次）不仅能提高设施番茄产量，还能在一定程度上提高番茄品质和土壤养分含量，是设施番茄肥料减施最佳处理。

Abstract: In order to explore the application effects of water and fertilizer coupling on facility tomatoes and its contribution to fertilizer reduction, a field experiment was conducted to study the effect on yield, quality of tomatoes and soil nutrients under the condition of 20% and 40% reduction of base fertilizer and 15% reduction of irrigation amount under the condition of water and fertilizer coupling in facility. The results showed that the yield of medium water and medium fertilizer (W2F2) treatment was the highest, which was significantly higher than that of other treatments, and the yield was 2.0% higher than that of high water and medium fertilizer (W1F2) treatment and 4.1% higher than that of conventional treatment (W1F1). Compared with conventional treatment , the contents of soluble solid, vitamin C in tomatoes, and soil organic matter, alkali-hydrolyzed nitrogen, available phosphorus and available potassium contents of W2F2 treatment increased by 1.5%, 5.8%, 6.5%, 6.3%, 4.5% and 10.6%, respectively. It indicated that medium contents water and medium fertilizer treatment (80% conventional fertilization + drip irrigation to 85% of field water capacity, and 51 kg/hm2 of large elemental water-soluble fertilizer used for 4 times with water) could not only improve the yield of facility tomatoes, but also improve the tomato quality and soil nutrient content to a certain extent, which was the best treatment for fertilizer reduction of facility tomatoes.
