摘要
复播青贮玉米是一季有余,两季不足地区出现的复种新形式。总结分析了其理论基础:一是复播青贮玉米能够最大限度地利用下茬有限的热量、水分和光照资源,抗低温、早霜等逆境能力强,生产风险小;二是其生物产量高,已有实践表明,青贮玉米是高产的复播饲料作物;三是其营养价值丰富,微量元素和维生素含量较高,是优质的粗饲料。发展复播青贮玉米,能够解决畜牧业饲料短缺问题,对减轻人畜争粮矛盾,保障我国粮食安全具有重要的实践意义。
Silage corn for the aftercrop is a new pattern of double cropping in the areas where heat resource is excess for planting once but deficient for planting twice in effective growing season.The author thought that silage corn for the aftercrop had three theoretical bases：1.It can utilize furthest the limited resource of heat,water and sun light and can resist the adversity caused by low temperature and first injurious frost.So it had the lesser risk of failure;2.Its biological production was high.It was proved that silage corn for the aftercrop was one of the high-yielding grass crops for aftercrop;3.It had high nutritive value with more microelements and vitamins and it was a kind of good stock food.Planting it can solve the problem of shortage of feed in stock farming and alleviate the contradiction between food and feed and even befits our food safe.
