农大108玉米杂交种,因具有较强的抗倒伏、耐旱、耐涝、耐瘠薄、抗病性强、稳产性好、增产潜力大等优点。加之活秆成熟,玉米收获后,秸秆可青贮,秸秆利用率高,为畜牧业发展提供了优良的青贮饲料,是我国目前推广的玉米主要品种之一。但由于北方地区制种生育期偏长、种皮厚、种子脱水慢、很容易受冻害,因此,在北部风沙滩地区防冻害生产出优良、发芽率符合要求的种子,可采取如下技术 Nongda 108 hybrids of maize, because of its strong lodging, drought, waterlogging, barren resistance, disease resistance, good stability and yield, yield potential and so on. Coupled with the living straw mature, corn harvest, the straw can be silage, straw utilization is high, for the development of animal husbandry provides an excellent silage, is China’s current promotion of one of the main varieties of corn. However, due to the long period of seed production in the northern part of the country, the seed coat is thick and the seeds are dehydrated slowly, it is easy to be frostbite. Therefore, frost damage in the northern windy beach produces excellent seeds with satisfactory germination rate. The following techniques
