Problems solved by technology

[0002] In recent years, the public's demand for grapes has been increasing, but due to seasonal or demand fluctuations, grapes are often wasted because they cannot be kept fresh for a long time, resulting in economic losses for fruit farmers and seriously affecting the healthy development of the grape industry.
[0003] Commonly used fresh-keeping methods, such as the special preservatives for grapes made of sodium bisulfite or potassium sulfite plus silica gel introduced on pages 428-429 of "Fruit and Vegetable Storage Principles and Practical Technologies", often release SO 2 , while SO 2 It will be converted into sulfite and remain in the fruit, causing certain harm to human health

Embodiment 1

[0035] When the fruit is ripe, the fruit stems are circumcised, and the fruit stems are circumcised at 0.5cm, 1cm, and 1.5cm from the main trunk. With no circumcision as the control, 20 fruit ears are circumcised for each treatment, and the fruit TSS, Changes in hardness and flavor, the results are shown in Table 1 and Table 2.

[0036] It can be seen from Table 1 that the decrease in soluble solids and hardness of the control fruit was higher than that of the ring-cut treatment when the fruit ripened to 15 days after the circumcision of the fruit stems of 'Xiahei' grapes, but the differences among the treatments were not significant; The soluble solids and hardness of the control fruit at 30 days and 45 days were significantly lower than those of the circumcision treatment, but the difference was not significant among the three circumcision treatments; the control fruit was soft, light in flavor, and poor in commodity value at 45 days after circumcision, while the three circum...

Abstract

The invention provides a grape on-tree storage method. The grape on-tree storage method comprises the step that girdling is conducted on stems when fruits are ripe, wherein girdling is conducted in the mode that the position, 0.5-1.5 cm away from a truck, of each stem is girdled by one circle. The grape on-tree storage method enables the on-tree storage period of summer black grapes to belonger than 45 days, and can make red-globe grapes keep good TSS after at least 90 days of on-tree storage. The grape on-tree storage method has the advantages that required operation is simple, the on-tree storage effect is remarkable, and the market application prospect is huge.

Description

technical field [0001] The invention belongs to the technical field of viticulture, and in particular relates to a method for keeping grapes fresh. technical background [0002] In recent years, the public's demand for grapes has been increasing, but due to seasonal or demand fluctuations, grapes are often wasted because they cannot be kept fresh for a long time, resulting in economic losses for fruit farmers and seriously affecting the healthy development of the grape industry. [0003] Commonly used fresh-keeping methods, such as the grape-specific preservatives made of sodium bisulfite or potassium sulfite plus silica gel introduced on pages 428-429 of "Fruit and Vegetable Storage Principles and Practical Technologies", often release SO 2 , while SO 2 It will be converted into sulfite and remain in the fruit, causing certain harm to human health. [0004] Therefore, urgently need to develop a kind of safe, efficient grape vine fresh-keeping method. Contents of the inv...
