Ginger used for storage should be dried in the middle and late 11 months and the upper part of the ground to become yellow and rootstock. When the rhizome is fully expanded, it will choose sunny weather, dry tubers without mud, pick up stems and leaves, remove plague ginger, sub ginger and machine damaged ginger. The key to storage is heat preservation, and the following four methods are introduced:
A closed storeheap: strict selection of ginger, leaving the better quality of the bulk in the warehouse, hay straw covered storage, preparation. Then assembled in a southerly direction warehouse wall, separated a small warehouse, and the brick wall with mud brick joint anti jam, the cold wind blowing, ginger stacked in the brick wall, Jiang Duigao 2 meters in pile evenly into some reeds into the ventilation tube to the top for ventilation. In the storage, the corner does not leave the gap, and the middle can be slightly loose. Piled up immediately after the mud or straw closed top, heap storage should not be too large, generally every library to piled up around 5000 kg. Temperature control in general 18C 20C, when the temperature drops, can increase the insulation cover; if the temperature is too high, can reduce the mulch in the cooling.
Two, pit storage: where the underground water level is high, the pit is used to store ginger. The depth of the pit is based on the principle of no water. It is generally 1 meters deep, and the diameter is 2 meters. The width of the pit is wide, narrow, round or square, and a hole can store about 2500 kilograms. A straw bar is placed in the center of the pit to facilitate ventilation and temperature measurement. When ginger is placed, it starts with a layer of ginger leaf and then covers a layer of soil. Then it will cover the soil with temperature drop. Covering a total thickness of 60 cm to 65 cm, to keep the reactor with storage temperature suitable principle of pit with straw as round spires for rain, located around the drainage ditch, a cold north wind.
The management of storage should not only prevent heat, but also prevent cold. At the beginning of the entry, the temperature is easy to rise, and the pit can not be closed completely. For the first 1 months, the higher pit temperature is required. It needs more than 20C. After that, it will remain at 15C. In winter, it must be sealed to prevent the low temperature of the pit. The storage should always check the ginger has no change, the bottom can not have water.
Three, sediment burial burial pit by brick and stone in the warehouse or basement built, about 0.8 meters high, 1 meters in width, unlimited length, storage first at the bottom layer about 5 cm thick, the moisture content is about 10% of the sediment, then add some ventilation tube, then select good ginger in pit mud, a layer of ginger (ginger four or five thick) a layer of mud, piled to about 5 cm away from the pit. In the end, it is covered with silt, and the ginger is not exposed to the air.
During storage, we should check the change of temperature inside the stack regularly, and adjust it by thickening or removing the covering to make the storage environment keep relatively stable temperature and humidity, so don't turn it over easily.
Four, the storage of air raid shelter: a layer of sand and a layer of ginger, and pile up to 1 meters high, 1 meters wide rectangular buttress, each stack 1250 to 2500 kilograms. In the middle of the stack, a ventilating bundle with a diameter of 10 centimeters is made up of a thin bamboo pole, and placed into a thermometer to measure the stack temperature. Wet sand seal stack around the seal end duo, mask good portal, hole on the left to avoid the cold air blowing hole.
After storage for a week, the temperature gradually increased to 25C 30C. After 6 to 7 weeks, the temperature gradually decreased to 15C. The color of ginger turned yellow, and it had aroma and pungent taste. At that time, it could open the door and turn it off when it was cold. In the later storage, the temperature should maintain 12C - 15C for a long time. After the beginning of spring, such as relative humidity less than 90% to 95%, at the top of the Rick surface sprinkle some water. If there is a bud phenomenon, it shows that the temperature is too high and can be ventilated. If the ginger stacking is sunken and has a peculiar smell, it should be checked for the phenomenon of disease.
