在农作物中,蚕豆是一种大粒种子,其子叶含有丰富的蛋白质和少量脂肪,种皮比较坚韧。蚕豆贮藏最突出的问题是虫害和蚕豆种皮变色。虫害主要是蚕豆象危害,通常以成虫越冬,隐蔽在仓房角落隙缝里或田间枯枝草丛里,第二年3月成虫产卵子刚发育的嫩荚上,孵化后,幼虫钻入豆粒内逐渐成长。当蚕豆成熟收获后,就一同带入合内继续危害,到8月初羽化为成虫,从豆粒内穿小孔飞出,躲藏在仓库内越冬,到来年蚕豆开花结荚时,又飞到田间交尾产卵,孵化幼虫蛀食豆粒。这样循环往复,使蚕豆品质下降,严重损耗,生活力丧失。种皮变色,往往随着贮藏期的延长而发生,首先从内脐和豆粒侧面隆起部分出现,由呈浅褐色,慢慢地变深褐色、暗红色或黑色。变色的原因主要由于蚕豆 In crops, broad bean is a large seed, its cotyledons are rich in protein and a small amount of fat, the seed coat is relatively tough. Vicia faba storage of the most prominent issue is pests and broad bean seed coat discoloration. Insect pests mainly like Vicia faba, usually adult wintering, hidden in the warehouse corner crevice or field withered grass, the second year in March the adult oviparous development of newly developed soft pods, after hatching, larvae into the bean gradually growing up. When the broad beans mature harvest, they will be brought together to continue to endanger the disease, until early August eclosion into adults, from the hole through the holes in the beans fly out, hiding in the warehouse overwinter, the arrival of Vicia faba blossom in the coming year, then fly to the field of mating Spawning, hatching larvae eaten beans. This cycle of reciprocation, so that the quality of broad beans decreased, serious loss, loss of viability. Seed coat discoloration, often with the extension of the storage period occurred, first from the umbilical and legumes bulge part of the emergence of a light brown, slowly dark brown, dark red or black. The main reason for discoloration is broad beans
