Problems solved by technology

[0004] The prior art shows that salicylic acid (SA) or salicylic acid and sodium nitroprusside (SNP) mixed solution has been used to improve the preservation of peaches, fresh flowers, strawberries, etc., but using salicylic acid or salicylic acid and sodium nitroprusside (SNP) The sodium nitroprusside mixture will reduce the effective ingredients beneficial to the human body such as chlorophyll, carotenoids, total phenolics in the peel, total flavonoids, free amino acids and vitamin C. There is an urgent need for a grape that can improve nutrients but has a good fresh-keeping effect. substances and methods

Embodiment 1

[0029] Embodiment one: the method that salicylic acid of the present invention improves grape superoxide dismutase activity

[0030] The invention provides a kind of method that salicylic acid improves grape superoxide dismutase activity, and described method comprises the steps:

[0031] (1) Add salicylic acid and Tween-20 into deionized water to form a salicylic acid aqueous solution with a concentration of 1.0 mmol / L, and the volume fraction of Tween-20 in the solution is 0.05%.

[0032] (2) Select fruit ears with consistent growth potential and good lighting, and spray grape ears in four stages: flowering stage, swelling stage (late July), color change stage (late August) and 2 days before harvest (mid-September). Apply the formulated salicylic acid treatment.

[0033] (3) Each stage of spraying is divided into several times to spray the fruit surface, spray evenly, spray about 200mL of liquid on each cluster of fruit ears, and dry it. After each stage of spraying, start ...

Embodiment 2

[0036] Embodiment two: the optimization test of salicylic acid concentration of the present invention

[0037] Three salicylic acid (SA) treatment concentrations were set in the experiment, which were 0.5mmoL / L (S1), 1.0mmoL / L (S2), and 2.0mmoL / L (S3), and each salicylic acid solution contained a volume fraction of 0.05 %Tween-20, with water as the control group.

[0038] Select ears with consistent growth potential and good light, and spray salicylic acid on grape ears during the flowering period, late July (expansion period), late August (color change period) and mid-September (2 days before harvesting) . Spray the fruit surface several times in each stage, and spray evenly. Spray about 200mL of liquid medicine on each cluster of fruit ears in each stage, and dry it. A single plant is 1 repetition, and the average value is taken after 3 repetitions. After normal harvesting and pre-cooling, the laboratory was inoculated with Botrytis cinerea, and left for 60 days to measure...

Embodiment 3

[0043] Embodiment three: the method that salicylic acid of the present invention improves grape superoxide dismutase activity

[0044] The use method of the method for improving the activity of grape superoxide dismutase by salicylic acid of the present invention, the drying temperature controlled by the temperature control device is 24°C-35°C, and the wind speed controlled by the temperature control device is 8.0m / s~10.7m / s s, the amount of irrigation after fertilization is 10m 3 / hm 2 -15m 3 / hm 2 , The drip irrigation pipe is 40cm-60cm away from the grape roots, and the fertilization distance is 20cm-40cm from the grape roots.

Abstract

The invention provides a method for improving the activity of grape superoxide dismutase by salicylic acid. The method comprises the following steps: preparing a salicylic acid solution with the amount-of-substance concentration of 1.0mmol / L and introducing Tween-20 with the volume percent of 0.05 percent; carrying out salicylic acid spraying treatment on grape clusters at four phases including aflowering phase, a swelling phase, a color changing phase and 2d before harvesting, and drying; after spraying, applying grape fresh-keeping and quality-improving fertilizer after sunset in the afternoon in the same day, and irrigating. According to the method provided by the invention, the preservation time of grapes is prolonged for more than 40 percent; inner anti-oxidization power is providedthrough the grape fresh-keeping and quality-improving fertilizer, so that the content of various nutrient components is not reduced but raised after the grapes are subjected to fresh-keeping treatmentthrough the salicylic acid; meanwhile, the loss speed of the nutrient components is extremely delayed after the grapes are picked, the quality guarantee period of the grapes is prolonged and the quality of the grapes is improved; the method has wide applicability in the field of grape planting.

Description

technical field [0001] The invention relates to the technical field of fresh-keeping agricultural products, in particular, the invention specifically relates to the technical field of fresh-keeping grapes with salicylic acid. Background technique [0002] Grape is one of the leading industries in Xinjiang. It is deeply loved by consumers and has a huge market potential. However, due to the thinner grape skins, high water content, and delicate tissues, they are easily damaged during the picking process, and problems such as shattering, browning, dry stems, and rot are prone to occur during storage and distribution, which not only affects the freshness of the grapes, but also cause certain economic losses. [0003] At present, the grape preservation technology at home and abroad is mainly low temperature combined with SO 2 Antiseptic storage. Although SO 2 Fumigation can effectively control postharvest rot and maintain fruit quality, but due to SO 2 The dose that causes d...
