为了提高设施黄瓜栽培的水分利用效率，探索设施黄瓜节水栽培模式。试验以黄瓜为试材，以农民经验灌溉灌水量为对照，研究了控制灌水定额对嫁接和自根黄瓜光合生理、产量和水分利用效率的影响。研究结果表明：适当减少灌水量对于增强黄瓜光合速率和提高水分利用效率效果显著。在试验中控制80%～85%灌水下限处理（I1处理）下黄瓜光合速率和叶绿素含量均较农民经验灌溉（I2处理）显著提高；I1处理下嫁接和自根黄瓜水分利用效率也较I2处理有显著提高。与自根黄瓜相比，嫁接可以显著增加黄瓜光合作用、产量和水分利用效率。在I1处理下，嫁接处理（G）比自根黄瓜增产7.16%，提高水分利用效率7.16%；在 I2处理下，嫁接黄瓜比自根黄瓜增产7.84%，提高水分利用效率7.83%。总之，I1-G处理在黄瓜光合作用、产量和水分利用效率等方面表现最优，是生产实践中较好的栽培和水分管理模式，具有推广价值。
為瞭提高設施黃瓜栽培的水分利用效率，探索設施黃瓜節水栽培模式。試驗以黃瓜為試材，以農民經驗灌溉灌水量為對照，研究瞭控製灌水定額對嫁接和自根黃瓜光閤生理、產量和水分利用效率的影響。研究結果錶明：適噹減少灌水量對于增彊黃瓜光閤速率和提高水分利用效率效果顯著。在試驗中控製80%～85%灌水下限處理（I1處理）下黃瓜光閤速率和葉綠素含量均較農民經驗灌溉（I2處理）顯著提高；I1處理下嫁接和自根黃瓜水分利用效率也較I2處理有顯著提高。與自根黃瓜相比，嫁接可以顯著增加黃瓜光閤作用、產量和水分利用效率。在I1處理下，嫁接處理（G）比自根黃瓜增產7.16%，提高水分利用效率7.16%；在 I2處理下，嫁接黃瓜比自根黃瓜增產7.84%，提高水分利用效率7.83%。總之，I1-G處理在黃瓜光閤作用、產量和水分利用效率等方麵錶現最優，是生產實踐中較好的栽培和水分管理模式，具有推廣價值。

The experiment was studied to improve water use efficiency of cucumber in greenhouse and explore cultural model with economizing water. As the contrast of irrigation amount in experience of farmer, the cucumber were tested as the experimental materials to study the effect of controlling irrigation quantity on photosynthetic physiology, yield and water use efficiency of grafted cucumber and self-rooted cucumber in the greenhouse. The results showed that as follows: there were obvious effects of appropriately reducing irrigation quantity to promote photosynthesis and improve water use efficiency. The treatment of I1 was significantly more than the treatment of I2 in photosynthesis and chlorophyll content of cucumber. Compared with self-rooted cucumber, grafted cucumber had better performance in photosynthesis, yield, and water use efficiency. In the treatment of I1,yield and water use efficiency of grafted cucumber respectively improved 7.16%,compared with self-rooted cucumber;In the treatment of I2,yield and water use efficiency of grafted cucumber respectively improved 7.83%,compared with self-rooted cucumber. On the whole, in this experiment, the treatment of I1-G had best performance in the hand of photosynthesis, yield, and water use efficiency, was a better cultivating and irrigation mode, and had a promotional value.
