1, cylinder method. Wash the cylinder upside down, so that the water droplets in the tank are finished. Then wipe the inner wall with a clean cloth, wipe with 70% alcohol, and put the treated grapes layer by layer into the cylinder. Each layer is 15-20 centimeters thick. Put a bamboo curtain-shaped bracket between the layers to prevent grain breakage and rot. After filling, seal it with polyethylene plastic film and place it in a cool place. Then dig a hole in the shade and place the tank in the pit, gradually increasing the cover as the temperature decreases. This method can store grapes on New Year's Day and Spring Festival. 2, the ditch method. Dig a ditch that runs from north to south, 10 meters long, 80 centimeters deep, 1 meter wide and 30 centimeters wide. Spread 5 to 10 centimeters thick dry sand at the bottom of the ditch, and mix 6% wettable sixty-six powder 150 to 200 grams. Amount of wet sand is thrown into the ditch to kill insects and prevent rats. The processed grapes are discharged to the bottom of the fine sand on the bottom of the gully. A layer of wet sand and a layer of grapes can be piled on 3-4 layers, and finally cover 20-30 cm thick wet sand. It is covered with straw mats at the beginning, covered during the day and opened at night. When the temperature dropped to 12-2°C during the day, the mats began to cover at night and the covering gradually increased as the temperature decreased. 3, cellar storage. Place the processed grapes in baskets or boxes and place them in a pre-cooling place. Lay bricks or sleepers to facilitate ventilation. Cover the reeds and shade them until they enter the pit after light snowfall. In the cellar, a 60-70 cm pad is placed on the wooden floor and the basket is placed on the pad. Put a wooden strip or straw on the basket or box, put the basket or box on top, and then place three layers in order to show the character shape. Each cellar is placed in 3 to 4 rows with pedestrians in the middle. After entering the pit, use ventilation, watering and other methods to maintain the temperature and humidity of storage. It is not advisable to turn the grapes during storage and to prevent rat damage. 4, bungalow storage. Choose a well-ventilated room and treat it by disinfection. Put the treated fruit into the basket with the handle upside-down, and place each ear in a staggered manner, preferably 20-25 kg per basket. In the interior shelf, 60-70 centimeters from the ground, after the first layer of fruit basket is placed, the basket is placed on the wood, and then the second layer, followed by. Keep pedestrians in the middle for ventilation. The indoor required temperature is 0 - 1°C. When the temperature is low, it needs to be fired. The relative humidity is 80% - 90%. When it is dry, water can be poured on the floor to increase humidity. 5, cold storage. The treated grapes are packed in bags of 4-5 kg ​​grapes made of 0.04 mm thick polyethylene film and sealed. Maintain the temperature of the library -1.5 °C -0 °C, relative humidity of 90% -95%, oxygen 2% -5% can be. China Agricultural Network Editor
