以利用外界自然冷源为基础的土窑洞苹果贮藏技术在山西等地已得到普遍推广并且收到了良好的效果.但是,管理这种土窑洞必须十分注意的是当外界气温低于-6℃时便不宜再通风以免冻伤果品.这显然是不合理的.1986年,我们建成了两个地下洞库.一个仅有主洞库.另一个在主洞库两侧各附建一副洞,用以在出现-6℃以下的天气时继续通风,达到充分利用外界冷源,降低周围土体温度的目的.几年来,在同样管理条件
To use the external natural source of cold-based underground kiln Apple storage technology has been widely promoted in Shanxi and received good results.However, the management of this cave must be very careful when the outside temperature is below -6 ℃ It is not appropriate to ventilate again in order to avoid frostbite fruit.It is obviously unreasonable.In 1986, we built two underground caverns, one has only the main cavern and the other has a hole in each side of the main cavern, In the event of -6 ℃ below the weather continue to ventilate, to make full use of external cold source, reducing the temperature around the soil purposes. In recent years, under the same management conditions
