This method enables grapes to be stored until mid-May of the following year. If the color is kept bright and the taste is delicious, it is not inferior to the fresh grapes harvested in summer and autumn, which can increase economic efficiency by 6 to 10 times. The method of rest is: The selection and design of the cellar site for the construction of the cellar: The cellar should be constructed with a slightly elevated, well-ventilated and shaded place. Cellar volume of 30 cubic meters, semi-underground, cellar body east-west direction. The cellar door is located on the Western Wall, 40 centimetres from the cellar, 1.6 meters high and 70 centimeters wide. At the east end of the pit, there is an air vent with a height of 40 cm and a width of 40 cm to facilitate ventilation and cooling at the beginning of storage. There are 3040 cm vent holes in the front and back walls, and a skylight with a height of 1 meter and a length and width of 60 centimeters in the pit floor. The air holes and skylights should have iron nets to prevent rat damage. 2 Pits Facilities: Pit walls with ash sanding, crypt walls can also be used. At the bottom of the pit, 3-4 cm thick sand is used to adjust the temperature. The cellar was built into a rack with coarse bamboo culms with a spacing of 40-50 cm. 30 cubic meters of cellar can store about 750 kilograms of grapes. 3 Storage pit disinfection: Before the grape enters the pit, it is sprayed with concentrated lime water to disinfect the whole pit. Then it was sealed and fumigated with 20 grams of sulfur powder per cubic meter for two days and then discharged. Do a good job of pre-storage Put the grapes into the basket after picking them, place them in a cool, damp place, pre-store for 2 days, reduce the temperature, and then put the grapes into the pit, which will reduce the pit temperature by 2°C. Timely picking into the cellar Before and after the “frostâ€, choose a full-fledged, high-quality grape ear, cut it with scissors, and retain the stem for about 10 cm. Carefully remove the diseased grains and green grains, gently handle them, hang them on the storage rack, and store fresh varieties of rose fruit, Kyoho, Hei Olin, Italy's secondary fruit, and a fruit of Zexiang, Longan, and Dabao. As well. Grape berry, thin and juicy, extremely difficult to store and transport, it is best to pick on the spot, enter the pit on the ground, minimize the number of handling. Practice has proved that thicker varieties of the skin, such as black Olin more resistant storage.
