| 为探明不同灌溉水平与通气水平对番茄生育末期的形态指标、生理指标、产量、品质和水分利用效率的影响。以富山1号番茄为试材,在日光温室进行了灌溉试验,设8个灌水水平和通气水平。结果表明,不同灌溉水平与通气水平对番茄生育末期形态指标、生理指标、产量、品质和水分利用效率均有显著影响。T2水平下,番茄的产量和水分利用效率均能达到较高的水平,分别为7.28 kg/m2和0.68 mmol/mol;T8处理的番茄灌层干物质累积、糖度、糖酸比、硬度和可溶性蛋白水平较高,分别为83.47 g、4.13%、13.61、3.77、0.28μg/g;T4处理的茎粗最大,为0.98 cm;T6处理的株高最大,为135.00 cm;在T7、T6的灌溉水平和通气水平下,番茄的生理指标较高。在相同灌水水平下,加氧灌溉能显著提高番茄品质、生理指标和形态指标,但是对产量、水分利用效率以及茎粗的提高并不显著。 |

| In order to study the effects of different irrigation levels and ventilation levels on some indexs of tomato, including morphological indexes，photosynthetic indexes, yield, quality and water use efficiency， with Fushan No. 1 as matierial，we did an eight-level irrigation and ventilation experiment in greenhouse. The conclusion is that there is signif-icant effect of different irigation levels and ventilation levels on some indexs of tomato，including morphological indexes， photosynthetic indexes，yield, quality and water use efficiency. Under T2 level, the yield and water use efficiency of tomato can reach a high level, being 7.28 kg/ m2 and 0. 68 mmol/mol repectively. Under T8, the sugar, sugar/ acid, hardness and soluble protein are high, being 83.47 g，4.13%, 13.61, 3.77 and 0.28 Pg/g respectively. The stem di-ameter is the maximum in T4, reaching 0.98 cm. The plant height is the maximum in T6, reaching 135. 00 cm. Under the levels of T7 and T6，physiologjical indicators of tomato is high. T8 treatment can significantly increase the plant height and dry matter accumulation in shrub layer. At the same level of irrigation, oxygenated imigation can significantly improve the quality，physiological and morphological indicators of tomato, but there is no significant effect on yield, wa-ter use efficiency and stem diameter. |
