| 摘 要： | 为探索设施西瓜栽培的最优灌水策略，以“早佳8424”西瓜为研究对象，在早春塑料大棚栽培模式下，以常规滴灌为对照，设置3个交替根区滴灌处理(灌水上限分别为70%、80%、90%田间持水量)，研究不同灌溉模式对西瓜生长、产量、品质、养分吸收及水分利用效率的影响。结果表明：交替根区滴灌处理(灌水上限和下限分别为90%和60%田间持水量)的综合性状最好，其主蔓长、叶绿素相对含量(SPAD值)、平均单果质量、产量及果实中心可溶性固形物含量、全氮含量、全钾含量均较对照显著提高；理论产量达48 217.5 kg/hm2，水分利用效率达78.21 kg/m3，较对照分别增长11.09%和35.50%；且较对照节水33.01%，具有明显的节水效果和较高的水分利用效率，不仅促进了西瓜生长、品质提升以及养分吸收，同时可以实现高产、节水，有效提升灌溉水分利用效率。

| Abstract: | Abstract: In order to explore the optimal irrigation strategy for the cultivation of watermelons in facilities, three treatments of alternate partial root-zone irrigation (APRI, the upper limit of irrigation was 70%, 80% and 90% fi eld moisture capacity, respectively) were set up under the cultivation mode of plastic greenhouse in early spring, taking conventional drip irrigation as the control and watermelon ''Zaojia 8424'' as material. The effects of different irrigation modes on the growth, yield, quality, nutrient absorption and water use effi ciency of watermelon were studied. The results showed that the APRI treatment (the upper limit and lower limit of irrigation were 90% and 60% fi eld moisture capacity, respectively) had the best comprehensive characteristics, and the main vine length, SPAD value, average fruit weight, yield, central soluble solid content, total nitrogen content and total potassium content signifi cantly increased compared with the control. The theoretical yield was 48 217.5 kg/hm2, and the water use effi ciency was 78.21 kg/m3, which increased by 11.09% and 35.50% compared with the control, respectively, and could save water by 33.01%, which had obvious water saving effect and higher water use effi ciency. This treatment could not only promote the growth, quality and nutrient absorption of watermelon, but also achieve purposes of high yield and water saving, and effectively improving irrigation water use effi ciency. |
