日本细切捆包青贮的研究与应用

Research and Application of Finely Chopped Round Bale Silage in Japan

牧草捆包青贮在国外已普及利用几十年,而玉米等粗大型饲料作物由于打捆、裹包难度大,一直未能很好解决,我国近年主要利用揉切固定捆包,作业效率较低。本文论述了日本近年研制开发的细切捆包新技术体系、细切捆包青贮的捆包特性、发酵品质、奶牛利用效果以及存在问题和发展前景,以期为我国细切捆包青贮的发展提供借鉴与参考。

The wrapped round bale silage for grasses has been developed and utilized for several decades overseas,but it is not available to bulky crops,due to difficulty of baling and wrapping.,Rolling and cutting or fixing bale packing are utilized to treat whole plant corn or corn stalk with low work efficiency in China in recent years.The present review introduces a new chopping bale system developed by Japanese researchers with discussion of the characteristics of baling,silage fermentation and utilization,disadvantages in present stage,and its perspectives for silage production.
