摘要
以“蓝山大白”苦瓜品种（Momordica charantia L．）为试验材料，在遮雨栽培条件下，研究了田间持水量50％～60％、70％～80％、90％～100％土壤水分含量（S、vC）条件下，初果期、盛果期、末果期果实的营养品质和产量。结果表明：就品质的水分效应而言，70％～80％SWC有利于果实维生素C、可溶性糖、可溶性蛋白质含量的提高，50％～60％SWC有利于增加果实可溶性田形物含量；关于品质的时期效应，3种土壤水分条件下均表现为盛果期果实维生素C、可溶性蛋白质含量最高，末果期果实可溶性糖含量最高，而50％～60％SWC和70％～80％SWC的可溶性固形物在盛果期和末果期均显著高于初果期；关于果实产量，50％～60％SWC和70％～80％SWC之间差异不显著，但均显著高于90％～100％SWC的产量；盛果期果实品质普遍优于初果期和末果期，综合产量和品质，70％～80％SWC更利于苦瓜产量提高和品质改善。
Taking bitter melon （Mornordica charantia L. var ＇Lanshan Dabai ＇） as material, three soil water content treatments（SWC） were designed as 50%-60%,70%-80%,90%-100% of relative to the percentage of field water capacity,the SWC during different fruiting（early fruit stage,full fruit stage, late fruit stage） stages and yield of bitter melon under rain shelter were studied. The results showed that, 70% -80% SWC was benefit for vitamin C content, soluble sugar content and soluble protein content,while the 50% - 60 % SWC was benefit for soluble solid content;Three SWC treatments had the same trends of nutritional quality changes., vitamin C content, soluble protein content reached maximum content at full fruit stage, soluble sugar content reached maximum content at late fruit stage,while -luble solid content reached maximum content at both full and late fruit stage under 50%-60% SWC and 70%-80% SWC;In terms of fruit yield,50%-60% SWC and 70%-80% SWC treatments were not significant difference,but both of them were significantly higher than 90%-100% SWC. The nutritional quality of full fruit stage was always better than other stage,and 70%-80% SWC was benefit for the quality and yield of bitter melon.
