一、蚕豆的变化特点蚕豆在贮藏过程中的不良变化主要是生虫和变色。1.生虫蚕豆的主要害虫是蚕豆象(俗称豆牛),通常以成虫产卵于刚发育的蚕豆嫩荚上,孵化后,幼虫钻入豆粒内危害。当蚕豆成熟收获后,连虫一同带入仓内继续危害,并羽化为成虫,从豆粒内穿小孔飞出,躲藏仓库内越冬。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,生活力丧失,造成严重的损失。因此在生产上采取田间杀虫和仓内防治相结合的技术措施,可以大大降低或有效防止蚕豆象的危害。2.种皮变色蚕豆的种皮颜色因品种不同而不
First, the changing characteristics of broad beans Broad beans in the storage process is the main adverse changes in pests and discoloration. 1. The main pests of broad beans are broad beans (commonly known as Beef cattle), usually adults to spawn in the newly developed Vicia faba, after hatching, larvae into the beans within the harm. When the harvest of faba beans mature, even the insects brought into the warehouse to continue to endanger and eclosion into adults, flying out of the hole through the holes in the beans, hiding the warehouse winter. When the flowering and podding of Vicia faba in the coming year, they flew to the field to lay eggs and hatch larvae to eat beans. This cycle of reciprocation, so that the quality of broad beans, loss of vitality, resulting in serious losses. Therefore, in the field of production to take insecticide and control of the warehouse combination of technical measures can greatly reduce or effectively prevent the harm of Vicia faba. 2. Seed coat discoloration Broad bean seed coat color due to different varieties instead
