高油玉米高效利用模式及效益比较研究

研究了高油玉米单种及与普通玉米混种等多途径高效利用模式。结果表明,与普通玉米相比,高油玉米全株生物产量高,子粒及全株营养价值较高,青贮饲喂家畜效果显著;高油玉米与普通玉米混种,利用高油玉米花粉直感效应能有效提高普通玉米子粒品质,花粉直感后高油玉米于蜡熟期全株收获用于青贮,效益比普通玉米单种提高36.31%;高油玉米籽粒成熟时其秆叶仍碧绿多汁,并具有较高营养价值和秆叶鲜产量,子粒收获后鲜秆叶仍可做青贮利用,混种通用型利用比普通玉米单种子粒产量提高7.14%,秆叶鲜产量提高29.41%。

Studies on Effective Application Model and Benefit Comparison of High Oil Maize

Different application models with high efficiency had been studied by using high oil maize monocultured or planted with ordinary maize.The results showed that High oil maize was of high quality for silage,which had higher organism yield,higher nutrition both in grain and whole plant,as well as higher effects in feeding livestocks.Through mixplanting high oil with ordinary maize,grain quality of ordinary maize had been improved effectively by xenia effects of high oil maize.In this model,whole plant of high oil maize was harvested for silage in dough stage,while ordinary maize was harvested for grain.Benefit of per area had been increased by 36.31%.In universal application model,high oil maize stem and leaves were still green and fresh after harvesting grain in mature stage,and they had higher nutrition and yield for silage.In this model,grain and stem yield had been increased by 7.14% and 29.41% respectively.
