摘  要：
在日光温室春茬盆栽嫁接黄瓜条件下,以不同生育时期的土壤水分水平为试验因素,采用正交设计研究了在开花前期、初瓜期、盛瓜期和结瓜后期不同土壤水分条件对黄瓜蒸腾量和产量的影响,得出黄瓜的耗水规律、产量与水分之间的函数关系。研究结果表明:黄瓜对水分的消耗基本呈现为开花前期与初瓜期小、盛瓜期大、结瓜后期小的规律,耗水高峰出现在盛瓜期,并对各生育期耗水量进行了量化;黄瓜总产量与总耗水量之间呈二次抛物线关系,最佳灌水量为393mm;水分生产函数的敏感指数按盛瓜期→结瓜后期→初瓜期→开花前期的顺序依次降低,与黄瓜耗水规律基本一致。

摘  要：
In Chinese solar greenhouse, the pot experiment about the effects of different soil moistures on transpiration(Ts) and yield was conducted during four growing stages of cucumber: early-florescence stage, early-fruit stage, exuberant-fruit stage and late-fruit stage. The results showed that the amounts of water consumption in early-florescence and early-fruit stage were lower than that at late-fruit stage, and at exuberant-fruit stage the amount of water consumption was the highest. The relationship between the total yield and the total amount of water consumption was quadratic parabola, and the optimal irrigation amount was 393 mm. Water sensitivity indices went down successively from exuberant-fruit stage, late-fruit stage, early-fruit stage to early-florescence stage, which was similar to the pattern of water consumption.
