浅谈玉米果穗青贮技术

Talking About Corn Ear Silage Technology

随着思路的拓宽和技术的发展,市场上研发出了一种新型的青贮饲料类型——玉米果穗青贮,制作原料为"籽粒+穗轴+苞叶、穗柄"等。笔者认为,这一新的青贮饲料即玉米果穗青贮非常适合我国的小农户生产和市场需求,有很大的发展潜力。一是不需要投入资金购置大型的青贮饲料制作机械,二是不需要更换品种,三是发展果穗青贮可以很好地解决目前我国玉米中存在的"水苞米"问题、籽粒烘干问题、马路晾晒玉米污染问题以及玉米籽粒侵染霉菌毒素超标等许多问题,四是果穗青贮的市场需求很大,五是如果很好地开发和应用果穗青贮技术,我国就能实现玉米和饲料产业的跨越式发展。玉米果穗青贮收获期为果穗成熟期,玉米果穗粉碎时最好选用锤片式粉碎机,果穗青贮经2个月以上的贮存就可以取饲。果穗青贮饲料可以作为奶牛、肉牛的精饲料使用,还可作为牧区牦牛冷季补饲的好饲料。

With the broadening of ideas and the development of technology, a new type of silage, corn ear silage, has been developed on the market. The raw materials are "seed + cob + eucalyptus, stalk, etc.". The author believes that this new silage, namely corn ear silage, is very suitable for the production and market demand of small farmers in China, and has great potential for development. First, there is no need to invest in large-scale silage production machinery;second, there is no need to change varieties;and third, the development of ear silage can solve the problem of "water glutinous rice" existing in corn in China, grain drying problem, drying on the road. There are many problems such as corn pollution and the overproduction of mycotoxin in corn kernels. Fourth, the market demand for ear silage is very high. Fifth, if the ear silage technology is well developed and applied, China can realize the leap-forward development of the corn and feed industry. The harvest period of corn ear and silage is the maturity stage of the ear. When the corn ear is crushed, the hammer mill is preferred. The silage of the ear can be fed after storage for more than 2 months. The ear silage can be used as a concentrate for dairy cows and beef cattle, and can also be used as a good feed for feeding yak in the pastoral season.
