一、气调法1.快速降氧法：将蒜苗堆放并用塑料帐密封后，连续抽氧灌氮3～4次，帐内含氧量要求控制在3％，二氧化碳在10％上下。2.自然降氧法：蒜苗进帐后即将塑料帐密封，帐内的氧气由蒜苗自行吸收。使氧分压逐渐下降到2％～4％。以后每天测定调节，使氧分压保持在所需要的范围 First, the air method 1 rapid aerobic method: the garlic seedlings stacked and sealed with plastic account, the continuous pumping of nitrogen 3 to 4 times the oxygen content of the account control in 3%, 10% of carbon dioxide up and down. 2. Natural hypoxia method: garlic seedlings plastic seal soon after the account, the account of the oxygen absorbed by the garlic seedlings. The oxygen partial pressure gradually decreased to 2% to 4%. After the daily determination of regulation, so that the partial pressure of oxygen to maintain the required range
