土壤中的可用水量与施肥量之间的相互作用通常会强烈影响作物生长。本研究调查了不同灌溉条件（低含水量[W-l]：50，与60%田间持水量（FMC）相似；中度[W-m]：70，与80% FMC相似；高[W-h]：90，与100% FMC相似）和施肥条件（亏缺肥料）下番茄作物（Lycopersicon esculentum Mill）的鲜果和抗氧化酶的品质。日光温室中[F-l]：195 kg ha(-1)氮(N)+47 kg ha(-1)五氧化二磷(P2O5)和适量[F-m]：278 kg ha(-1)N+67 kg ha(-1)P2O5)。结果表明，新鲜水果的品质以及叶片和果实中的抗氧化酶活性与土壤中的含水量有关。缺水灌溉改善了果实品质，推荐在温室条件下的番茄作物栽培中施用50～60%FMC，施肥量为195 kg ha(-1) N + 47 kg ha(-1) P2O5。
The interaction between water availability in the soil and fertilizer application rates often strongly affects crop growth. In the current study, the quality of fresh fruit and antioxidant enzymes of tomato crops (Lycopersicon esculentum Mill) were investigated under different irrigation (low water content [W-l]: 50 similar to 60% field moisture capacity (FMC); moderate [W-m]: 70 similar to 80% FMC; and high [W-h]: 90 similar to 100% FMC) and fertilizer conditions (deficit fertilizer [F-l]: 195 kg ha(-1) nitrogen (N) + 47 kg ha(-1) phosphorus pentoxide (P2O5) and moderate [F-m]: 278 kg ha(-1) N + 67 kg ha(-1) P2O5) in a solar greenhouse. The results showed that the quality of fresh fruits and the antioxidant enzyme activities in the leaves and fruits were related to the water content in the soil. Deficit irrigation improved the fruit quality and 50 similar to 60% FMC combined with fertilizer application rates of 195 kg ha(-1) N + 47 kg ha(-1) P2O5 is recommended for tomato crop cultivation under greenhouse conditions.
