(一)高寒地区的贮粮霉变及其根源在气候炎热的地区,广大保粮工作者为了安全保管粮食,往往千方百计的设法降低贮粮温度,甚至付出较大的代价,采用机械制冷。而在祖国广阔的高寒地带。低温冷冻的目的确是较容易达到的,这对我们安全保管粮食提供了十分方便,经济而有效的条件。然而,高寒地区的贮粮也常有虫霉事故发生,造成不应有的损失。内蒙古四子王旗在气温低于-15℃的76年1月菜籽发热霉变,粮温为25℃。霉烂损失了菜籽2万斤;77年4月呼和浩特粮库24万斤玉米发热。局部粮温高达58℃。虽经抢救,仍造成了1万8千 (I) Alpine mildew and its root causes In hot climates, most grain-conserving workers tend to try their best to reduce the temperature of stored grains in order to keep their grains safe. Mechanical refrigeration is the most cost-effective method. In the vast alpine region of the motherland. The purpose of cryogenic freezing is relatively easy to achieve, which provides a very convenient, economical and effective condition for our safekeeping of food. However, the accumulation of grain in the alpine region is also often caused by Helicoverpa armigera, resulting in undue losses. Inner Mongolia Siziwangqi in the temperature below -15 ℃ January 76 rapeseed moldy, grain temperature 25 ℃. Rotten loss of rapeseed 2 million pounds; April 77 Hohhot 240,000 pounds of grain storage of corn fever. Local food temperature up to 58 ℃. Despite the rescue, it still caused 18,000
