摘要 以三年生藤稔葡萄为试材,研究了双膜覆盖和早期阶段性加温对设施葡萄棚内温度、物候期及果实品质的影响。结果表明:与单膜对照相比,双膜和加温处理的日最高温度分别降低了3.4和4.8℃,40℃以上高温天气由6 d降到了3和1 d,日极端低温由0.8℃分别提高到4.2和7.7℃,活动积温分别提高了189和273℃。双膜及加温处理各物候期明显提前,成熟期提早至5月底;双膜和加温处理后虽然萌芽率略有降低,但坐果率提高,单性果率显著降低,果实硬度、色泽、可溶性固形物等品质指标都有不同程度提高。双膜覆盖和早期加温后种植效益显著提高,分别比单膜栽培提高了69.1%和116.6%。 The effects of double membrane mulching and early-stage heating treatment on the temperature , phe-nophase and fruit quality of 3-year-old Fujiminori grape in greenhouse were studied .The results showed that:Com-pared with the control , the daily maximum temperature of double membrane and heating treatments was decreased by 3.4℃ and 4.8℃, whereas the daily minimum temperature increased from 0.8℃to 4.2℃and 7.7℃.After double-membrane mulching and early-stage heating , the days of high temperature above 40℃reduced from six days to three days and one day , and the active accumulated temperature increased by 189℃ and 273℃ respectively .In double membrane and heating treatments , the phenological phases such as bud brust , anthesis and veraison were significant-ly ahead of schedule , and the harvest was advanced to mid-May.The fruit-setting rate increased after double-mem-brane mulching and early-stage heating , while the germination rates slightly reduced with a significant reduction in parthenocarpic fruit rate .Compared with the control , the fruit firmness, color, soluble solids and other quality indi-cators were improved in different degrees .Planting benefits were significantly improved after double-membrane mulc-hing and early-stage heating , and the benefit per 667 square meters was improved by 69.1 percent and 116.6 percent compared with the control .
