Embodiment 1

[0029] (1) Preparation of melatonin solution: Mix 50 mg melatonin, 1.0 g chitosan, 2.5 g salicylic acid, and 1 L water to prepare melatonin stock solution. They were diluted into three melatonin solutions with melatonin concentrations of 10 mg / L, 25 mg / L and 50 mg / L respectively.

[0030] (2) Selection of experimental fruit trees: 20 litchi trees with basically the same size, height, growth, number of fruit bearing, and maturity of fruit bearing were selected in the same orientation and similar area of ​​the orchard. 10 litchi trees were treated for each treatment, and sprayed with clear water was used as a control.

[0031] (3) Spraying melatonin solution before harvesting: After the litchi trees are in full bloom, spray melatonin solution on the crown of the litchi tree three times. The spraying times were as follows: the first spraying of melatonin solution with a concentration of 10 mg / L was carried out 60 days after the full flowering stage of litchi, and the second spra...

Embodiment 2

[0045] (1) Preparation of melatonin solution: Mix 100 mg melatonin, 0.5 g chitosan, 1.0 g salicylic acid, and 1 L water to prepare melatonin stock solution. They were diluted into three melatonin solutions with melatonin concentrations of 10 mg / L, 25 mg / L and 50 mg / L respectively.

[0046] (2) Selection of experimental fruit trees: 20 litchi trees with basically the same size, height, growth, number of fruit bearing, and maturity of fruit bearing were selected in the same orientation and similar area of ​​the orchard. 10 litchi trees were treated for each treatment, and sprayed with clear water was used as a control.

[0047] (3) Spraying melatonin solution before harvesting: After the litchi trees are in full bloom, spray melatonin solution on the crown of the litchi tree three times. The spraying time was as follows: the first spraying of melatonin solution with a concentration of 10 mg / L 75 days after the full blooming stage of litchi, and the second spraying of melatonin ...

Embodiment 3

[0053] (1) Preparation of melatonin solution: Mix 80 mg melatonin, 0.7 g chitosan, 1.6 g salicylic acid, and 1 L water to prepare melatonin stock solution. They were diluted into three melatonin solutions with melatonin concentrations of 10 mg / L, 25 mg / L and 50 mg / L respectively.

[0054] (2) Selection of experimental fruit trees: 20 litchi trees with basically the same size, height, growth, number of fruit bearing, and maturity of fruit bearing were selected in the same orientation and similar area of ​​the orchard. 10 litchi trees were treated for each treatment, and sprayed with clear water was used as a control.

[0055] (3) Spraying melatonin solution before harvesting: After the litchi trees are in full bloom, spray melatonin solution on the crown of the litchi tree three times. The spraying time was as follows: the first spraying of melatonin solution with a concentration of 10 mg / L 65 days after the litchi full flowering period, and the second spraying of 25 mg / L mela...

Abstract

The invention discloses a treatment method for inhibiting disease and peel browning of litchi fruit. The treatment method specifically includes: spraying a melatonin solution before picking of the litchi fruit; after harvesting, performing soak cleaning on the litchi fruit with acidic electrolyzed water; draining off moisture of the fruit and then performing modified-atmosphere package on the fruit with polythene film bags 0.015mm in thickness; storing packaged fruit at 25-28DEG C under relative humidity of 85%-90%; after 6 days of storage, reducing sickness fruit rate of the litchi fruit to be less than 15% and browning index less than 3. With the method, occurrence of disease and peel browning of the picked litchi fruit can be remarkably inhibited, and no adverse effect on quality of the litchi fruit is caused; in addition, the treatment method is not high in requirement for equipment, high in operability and easy to be used in production.

Description

technical field [0001] The invention belongs to the technical field of fresh-keeping of fruits and vegetables, and in particular relates to a treatment method for inhibiting litchi fruit diseases and peel browning. Background technique [0002] litchi( Litchi chinensis Sonn.) is a subtropical evergreen fruit tree of Sapindaceae Litchi. China is the country with the largest litchi cultivation area and the largest total output in the world, mainly distributed in Guangdong, Guangxi, Fujian, Hainan, Taiwan and other provinces. Litchi fruit is rich in nutrition, has high medicinal value and health care function, and is deeply loved by consumers. However, Chinese lychee fruits ripen in the high-temperature and high-humidity season from May to July in summer. After harvest, the physiological metabolism is vigorous, and fruit diseases, peel browning and other quality deterioration are prone to occur, which seriously affect the storage period and appearance quality of lychee fruit...
