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。
Under the condition of potted grafted cucumber in spring greenhouse in greenhouse, the effects of different soil moisture conditions on the growth and development of cucumber (Cucumis sativus L.) under different soil water conditions were studied by orthogonal design at early flowering stage, early melon stage, Transpiration and yield, cucumber water consumption rules, yield and moisture as a function of the relationship between. The results showed that: the consumption of cucumber water basically showed a small flowering early and early melon, melon growing large, the small rule of late fruiting, water peak appeared in the melon stage, and the water consumption during each growth period Quantified; cucumber total output and total water consumption showed a quadratic parabolic relationship between the optimal irrigation amount of 393mm; water production function of the sensitive index according to the whole melon period → fruiting stage → early melon → flowering stage in order of decreasing, And cucumber water consumption is basically the same.
