种子在贮藏过程中,由于温、湿度变化及水分的转移,当湿热的空气和较低温度的某一堆层相遇,种粒间隙中的水气量达到饱和时,水气便凝结在种子表面,出现结露。种堆出现结露可使局部水分增高,造成种子的发热和霉变。一、种堆结露的类型 1.上层结露。种堆的上层结露多发生在季节转换
During the storage of seeds, due to the change of temperature and humidity and the transfer of moisture, when the moist and hot air meets a layer of lower temperature, when the amount of moisture in the grain gap reaches saturation, the water and air condense on the seed surface, Dew condensation appeared. Heap condensation appears to increase the local moisture, causing the seeds of fever and mildew. First, the type of pile condensation 1. The upper dew. Stacks of the upper dew occurred in the season more conversion
