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 at storage temperature is recommended to be-1-0 ℃, which should be reduced as much as possible in this range.

Effect of Air flow on Pig growth
The effect of air flow on pig body is mainly to affect the heat dissipation of pig body. Under general environmental conditions, as long as there is air flow, it can promote the convection and evaporation heat dissipation of the body. When the ambient temperature is lower than the suitable temperature limit of the pig, the heat dissipation of the pig is increased due to the action of air flow, which makes the pig feel cold. at this time, more energy is needed to maintain the body temperature. On the contrary, when the ambient temperature is higher than the upper limit of the suitable temperature for pigs, because the air flow contributes to the heat dissipation of pigs, and when the air flow is large, the heat dissipation is more, so the wind speed is increased.
