| 摘 要： | 通过田间试验，研究不同灌溉模式与施肥方式对设施栽培条件下小型西瓜水分利用、光合特性以及产量品质的影响。研究结果表明，节水灌溉处理W3可在实现节水50％的基础上获得较高的产量，并且糖分测定结果显示，减少灌水对提高西瓜品质也有益处。根据光合特性分析结果，适当范围内控制土壤水分可促进西瓜的光合速率、气孔导度和蒸腾速率，并提高计算水分利用率。不同施肥处理研究结果显示，适当减少氮肥可明显提高西瓜品质，而磷肥处理与西瓜产量品质的关系不明显，需进一步研究。

| Abstract: | The field experiment is used to analyze the effect of irrigation and fertilization mode on the water use, photosynthesis characteristic and yield of watermelon in greenhouse. The results show that a higher yield with a water use of 50% has been got in water saving irrigation mode W3; it can also increase the sugar content of watermelon. Photosynthesis rate, stomatal conductance and transpiration can be enhanced by controlling the soil water content properly. And the suitable reduction of nitrogen fertilizer can obviously increase the sugar content of watermelon. |
