摘要
对温室内无土栽培的樱桃番茄在不同生育阶段进行了不同的水肥耦合试验，旨在揭示番茄产量与灌水量及施肥配比的内在关系。结果表明：灌水量、施肥配比及二者的交互作用对番茄产量的影响都极显著；生育期最优灌水量为8467．2m^3／hm^2，最优施肥配比为N：P2O5：K2O=2：1：3；6～11月份的最优灌水量都为试验的高水，6、7月的最优施肥配比为N：P2O5：K2O=2：1：2，8～11月的最优施肥配比为N：P2O5：K2O=2：1：3。
This paper＇s main purpose was to discover the internal relation between the tomatoes＇ yield and the amount of irrigation and fertilization ratio by carrying out the different experiments of water and fertilizer coupling on the landless planting tomatoes ＇ different growth stage in the greenhouse. The results showed that both the amount of irrigation and fertilization ratio together with their interaction had remarkable influence on the tomatoes ~ yield. The most appropriate amount of irrigation was about 8467. 2 m^3/hm^2 and the most appropriate fertilization ratio is N：P2O5：K2O=2 ： 1 ： 3;The most appropriate amount of irrigation is maximum in from June to November in the experiment. The most appropriate fertilization ratios respectively are 2 ： 1 ： 2 in June and July and 2 ： 1 ： 3 in from August to November.
