| 摘 要： | 目的]利用"沾化冬枣",在陕西省科学院大荔现代农业科技示范基地露地栽培条件下,研究叶面喷施SOD,富硒肥和噻苯隆对冬枣品质的影响。方法]利用钼蓝比色法、氢氧化钠滴定法和紫外分光光度法等方法测定不同处理之下果实品质指标。结果](1)叶面喷SOD肥可显著提高冬枣可溶性糖、可溶性固形物含量,降低Vc和有机酸含量,降低采摘后15和30d的果实密度;显著提高了采摘期和采后24d的果实红色度,提早果实转色,促使冬枣提前上市,降低烂果率。(2)喷富硒叶面肥可显著提高果实中硒含量,提高果实可溶性糖含量,降低Vc和有机酸含量。(3)叶面喷施噻苯隆混合叶面肥,可提高冬枣可溶性糖、可溶性固形物和有机酸含量,降低采摘后15d的果实密度,但采摘后30d果实密度大于对照;推迟果实转色,促使冬枣延后上市,延长了冬枣市场供应期,降低烂果率,提高经济效益。结论]叶面喷施SOD,富硒肥和噻苯隆对冬枣品质产生了重要影响,它们在一定程度上提高了果实品质,其中喷施富硒肥可以提高果实的营养品质和保健功能,喷施SOD和噻苯隆则分别利于果实的提前和延后上市,延长冬枣货架期,提高经济效益。

| Abstract: | Objective] The impacts of spraying superoxide dismutase(SOD), selenium-enriched fertilizer and thidiazuron to leaves on winter jujube quality of Zhanhua winter jujube were researched under the condition of open cultivation in Dali agricultural science and technology demonstration base of Shaanxi Academy of Science.Methods] Fruit quality among different fertilizer treatments was determined by methods of olybdenum blue spectrophotometry, sodium hydroxide titration, ultraviolet spectrophotometry and so on.Results] (1) Spraying SOD to leaves significantly increased the contents of soluble sugar and soluble solids, meanwhile reduced the contents of organic acids and vitamin C, and decreased the fruit density after 15 or 30 days been picked. It also remarkably increased the red degree of fruit during the picking period and also the red degree after 24 days been picked, which were contributive to early fruit coloration and to put fruit into market earlier, and to reduce the rotten fruit ratio. (2) Spraying foliar selenium-enriched fertilizer significantly improved the selenium and soluble sugar contents in the fruit, and reduced the contents of organic acids and vitamin C. (3) Spraying thidiazuron mixed foliar fertilizer increased the contents of soluble sugar, soluble solids and organic acids, and decreased fruit density after 15 days been picked. The fruit density after 30 days been picked was higher than that of the contrast. Also, it can defer fruit coloration and fruit marketing, prolong store and supply period before marketing, reduce the rotten fruit ratio, and increase economic benefit.Conclusion] Spraying SOD, selenium-enriched fertilizer and thidiazuron to leaves had important influences on winter jujube quality. It improved fruit quality to a certain extent. The spraying of selenium-enriched fertilizer can improve the nutrition and health function of fruit; spraying of SOD or thidiazuron is more conducive to early or later marketing, prolongs supplying period, improves the economic benefit. |
