喷施不同叶面肥对冬枣品质的影响
Effect of Spraying Different Foliar Fertilizer on Winter Jujube Quality
摘要
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.关键词
