摘　　要：以黔阳无核椪柑为试验材料,分别于2007和2008年采用大棚、遮阳网等简易设施和地面覆膜措施,研究简易设施对椪柑果实品质的影响。结果表明:在延迟采收过程中,各简易设施均不同程度地提高了果实可溶性固形物和可滴定酸含量,降低了浮皮空间率,大棚和遮阳网之间的可溶性固形物和酸含量无显著差异;随着成熟期的推移,各处理的蔗糖、果糖和葡萄糖含量均呈上升趋势,而对照处理后期有下降趋势;成熟后期大棚和遮阳网覆膜处理的果实总糖含量显著高于对照,而2种处理之间无显著差异;2a中各简易设施处理果实的柠檬酸含量变化趋势基本一致,成熟后期酸含量要高于对照。The field experiments were conducted to delay the harvest cultivation of ponkan（Citrus reticulata Blanco cv.ponkan） in 2007 and 2008 using low-cost protected cultivation（plastic-film greenhouses and solar-shading nets） combined with ground plastic-film mulching.To evaluate the effect of protected cultivation on the improvement of fruit quality,the content of total soluble solid,titratable acidity,sugars and acids in ponkan fruits were measured under different cultivation models.Results showed that total soluble solid and titratable acidity of fruits from low-cost protected cultivation were higher than that of untreated control,while the volume of puffiness rate was significantly lower than that of the control.There was no significant difference in total soluble solid and titratable acidity between plastic-film greenhouses cultivation and solar-shading nets protected cultivation in the late development season of fruit.The sucrose,glucose and fructose content of all treatments increased with fruit maturity,whereas those of the control decreased in delayed harvest.Total sugars of fruits from ground plastic-film mulching in plastic greenhouses and plastic-film mulching under solar-shading nets were significantly higher than that of the control in the open field with delayed harvest,and there was no significant difference between two protective cultivations.The citric acid content during fruit maturation under different treatments shared a similar change,and the content of fruits from plastic-film mulching was higher than that of control in delayed harvest.
