光洁金黄的玉米,经过收获加工和贮存,由于现行技术上的问题,到消费者手中时,往往变成一种灰白破碎满布尘埃的产品。玉米籽粒残缺碎裂百分率过高,以及生霉和虫伤,引起质量降低。这些情况,是由直接机械损伤或间接受其影响所致。应根据玉米的最终用途来对现行玉米收获加工中总耗损量进行估价,除作青贮料外,一般机械破损率不宜过高。 Smooth, golden corn, harvested, processed and stored, often turns into a gray-shattered dusty product due to current technical problems in the hands of consumers. Maize grain incomplete fragmentation percentage is too high, as well as mold and insect damage, causing the quality to decline. These conditions are caused by direct mechanical damage or indirectly affected by them. According to the end use of maize, the current total loss of maize harvesting should be valued. Except for silage, the general mechanical damage rate should not be too high.
