魔芋是一种经济效益很高的作物,近年来各地都有大面积种植,因为用种量较大(每亩500公斤左右),休眠期较长,一般5～6个月不等,贮藏的适宜温度7℃～10℃,湿度要保持在70%～80%,但今年初几次出现温度偏低,且持续时间长,各地因管理不善,均出现不同程度的冻害。魔芋不耐低温。0℃以下,细胞内的游离水结冰,冰晶会破坏细胞和组织的结构,使其失去活力,待温度上升,冰晶消融,水分流出,组织变软,病菌侵入使其腐烂,球茎之间相互传染更加剧腐烂。因此,各地都要对贮藏的魔芋种材,认真检查,具体方法介绍如下:一、晴天检查并按魔芋种材受冻程度分别采取不同处理措施。 Amorphophallus is a crop with high economic benefits. In recent years, it has been planted in large areas because of the large planting amount (about 500 kg per acre), longer dormancy period and generally 5 to 6 months of storage Suitable temperature 7 ℃ ~ 10 ℃, humidity should be maintained at 70% ~ 80%, but the first few times this year, the temperature appears low, and the long duration, all due to poor management, there are varying degrees of frost damage. Konjac impatience with low temperature. Below 0 ℃, the free water in the cell is frozen. The ice crystal will destroy the structure of the cell and the tissue, making it lose its vitality. When the temperature rises, the ice crystal ablates, the water flows out, the tissue becomes soft, the bacteria invade and decay, Infection is even worse. Therefore, all over the store of konjac seeds, careful examination, the specific methods are as follows: First, the sunny check and according to konjac seeds cold degree were taken by different measures.
