How to store garlic bolts in winter

Temperature management of storage garlic belongs to the plant with strong cold resistance, and the garlic stalk, as the flower stem of garlic, still has strong physiological cold resistance. When the storage environment temperature reaches its freezing point, the fresh-keeping effect is the best.

The freezing temperature of garlic bolts is-0.8 ℃ 1 ℃ (depending on the content of solids). The freezing temperature of garlic bolts higher than-0.8 mol / L will not cause tissue icing, so it is safe. According to various practical experiences, the cold storage index of garlic stalk temperature is recommended to be-1-0 ℃. In this range, the upper temperature control index should be reduced as much as possible to reduce the temperature difference, so that the warehouse temperature is always in a low and constant state. At present, the main problem in reservoir temperature management is to worry about the freezing damage of garlic bolts, and the reservoir temperature index is on the high side, such as the lower limit index is higher than-0.5 ℃ and the upper limit temperature is higher than 0 ℃. If there are the above problems, we should adjust the air volume and balance the storage temperature of the normally open fan.

The regulation index of controlled atmosphere storage of garlic bolts in ordinary bags is 10% 14% carbon dioxide and 1% 3% oxygen. Carbon dioxide is the high limit index and oxygen is the low limit index. as long as one of the two indexes reaches the standard, the bag should be opened to adjust the air manually. At present, the general bagging volume is relatively large, considering that the time for the formation of the atmosphere control effect is relatively short, and the garlic bolts are in low oxygen and high carbon dioxide for a short time in each cycle, the carbon dioxide gas regulation index should be controlled in the high limit of the range value (14%). The oxygen index should be on the low side (1%). The most suitable gas combination for silicon window atmosphere is carbon dioxide 5% Mel 8%, oxygen 2% Mel 6%. In terms of the effectiveness of air conditioning, the concentration of oxygen is not higher than 10% and the concentration of carbon dioxide is not less than 5%, which will not have a great impact on storage. However, if carbon dioxide > 8% and oxygen < 2% are common in silicon bags, measures should be taken to adjust them.

The controlled atmosphere composition of the silicon bag is often limited by the air condition in the storeroom. if the carbon dioxide in the silicon bag is low or the oxygen is on the high side, less ventilation should be taken to increase the accumulation of carbon dioxide and the consumption of oxygen in the warehouse. In this way, the concentration of carbon dioxide in the bag will increase and the oxygen will decrease. On the contrary, it should be ventilated frequently.
