马铃薯的块茎,收获后均需贮藏一段时间。贮藏好坏,对种薯的生理特性、食用和加工用块茎的品质,都有很大影响。所以从收获后一直到块茎被利用以前,必须采取一系列有效措施,使块茎损失降到最低限度。一、贮藏期间的生理变化块茎在贮藏期间,尤其是收获后的最初阶段,由于吸呼作用,释放大量热能,使周围的空气及堆内温度增高,造成重量的损耗和化学成分的变化。重量的损失主要是由于萌芽、呼吸、蒸发和病菌侵染等原因造成的。1.萌芽刚收获的块茎,由于已进入休
Potato tubers need to be stored for some time after harvesting. Good or bad storage, the physical characteristics of seed, edible and processing tuber quality, have a great impact. So from harvesting until tubers are used, a series of effective measures must be taken to minimize the loss of tubers. First, the physiological changes during storage Tuber during storage, especially after the first harvest, due to the role of breathing, releasing a lot of heat, the ambient air and the temperature inside the reactor, resulting in weight loss and changes in chemical composition. Weight loss is mainly due to germination, respiration, evaporation and infection caused by bacteria and other causes. 1. Buds just harvested tubers, as has been into Hugh
