Hebei small package chestnut manufacturer takes you to know: chestnut storage skillfully

1. The method of transporting chestnuts is to use double gunny bags. This method is suitable for large transportation and storage. Before storage, prepare wet gunny bags immersed in water, and put chestnuts into dry gunny bags. Wet gunny bags can prevent chestnuts from losing water, and remove the outer layer after reaching the destination. OK, put the alternately arranged gunny bags in the refrigerator at 1-4 ° C. The evaporation capacity in the south is very large, and it takes 4-5 days to spray water once. When transporting in winter, it is necessary to put soft fillings (such as PU foil) in gunny bags to prevent freezing.

2. Sowing and preservation of chestnuts. Within 1 to 2 days after harvesting chestnuts, spray chestnuts with 200 times of 50% methyl tobuzin methyl ester solution to wet them. When spraying, rotate the chestnut fruit to fully contact the liquid. After spraying, immediately stir 3 times the amount of wet sand to form a pile of chestnuts with a width of 2 meters and a height of 50-60 cm, and cover it with a layer of wet sand, so that the chestnuts are invisible. Cover the outer layer with plastic film to keep the sand moist. After the fake goods are stored for about one week, the plastic film should be removed to check the chestnut pile to prevent the temperature in the pile from being too high or dry. Chestnuts used as seeds can be stored in this way.

3. The chestnuts stacked in the south are covered with corn straw or straw on the ground in a cool room, then sprinkled with about 5-6cm thick sand, and then stacked on the sand. Mix 1 part of chestnuts and 2 parts of sand, or alternate layers of sand and chestnuts, each about 3-6 cm. Cover with 3-7 cm of sand and straw, with a height of about 1 meter.

4. Before storing chestnuts in the northern wine cellar, dig a wine cellar with a width of 1 to 1.5 meters and a depth of 1 meter on the shady land with high terrain and good drainage. The length depends on the number of chestnuts. The bottom of the cellar is covered with 5 to 10 cm thick sand, mixed with chestnuts or layered alternately, with the same thickness as the stack. When the pile is 10-15 cm from the ground, fill it with sand and add soil to form a ridge. Cover with grass in cold weather. When filling, insert a firmly tied straw in the middle for ventilation. When the pile is in a long strip shape, a turf counter can be set every 1 meter. After filling, the straw shall be exposed.

5. Indoor storage methods should be harvested in sunny days, and chestnuts should be dry. The ball is big in color, full of complete disease-free nuts, hidden in a cool and ventilated room. Place a dry sand layer of 10-13 cm in the accumulation area, accumulate cones about 1-1.3 meters high, and cover them with chestnut shells. Turn it once a month, and it can be stored for 100 days. The color is still fresh, and the rotten fruit rate is less than 2%.

6. Store chestnuts in the stone cellar. In areas with Rocky Mountains, wine cellars can be built on a slope of 30-35 degrees, and the wine cellar door is located on the windward side of the local main wind direction in winter. There are three doors in the pit to form a buffer zone, which helps to stabilize the temperature in the pit. A 120 cubic meter pit can store 7500 kilograms of chestnuts. When the external low temperature is lower than the cellar temperature, please open the cellar door, air inlet and air outlet, and close it day and night to reduce the cellar temperature. When storing chestnuts, it is required to reduce the cellar temperature to 12 ° C. Before entering the wine cellar, wash the chestnuts with 10% brine to remove the floating secondary chestnuts, then soak them in 50% carbendazim 500-1000 times diluted solution for 1 hour, dry them and put them into a bamboo basket. Each basket holds 25 kilograms. At the beginning of storage, please try to reduce the cellar temperature to about 2 ℃. Spray water evenly in the cellar every 5 days, about 0.6 kg / m2 each time. Spraying 30ppm potassium permanganate liquid can prevent mold growth.
