拉伸膜裹包青贮技术研究进展

拉伸膜裹包青贮是指将收割好的新鲜牧草经捆包机高密度打捆，然后采用专业的拉伸膜进行缠绕裹包，在发酵所需的厌氧环境下形成的优质草料，是一种先进的青贮调制工艺。本文对裹包青贮在国内外的研究进展进行了综述，总结了影响裹包青贮的主要因素，分析了其在我国的应用和推广前景，并对裹包青贮研究中存在的问题提出了建议，以期为我国拉伸膜裹包青贮的进一步发展提供借鉴和参考。

Research Progress of Round Bale Silage Technology

Round bale silage was an advanced technology of silage modulation. The harvested fresh grass was bound to a high density bale with banding machine, and then wrapped the bale with the professional stretch film, finally fermented to the high-quality forage under anaerobic environment. The research progress of the round bale silage in domestic and overseas was reviewed and the main factors influencing the production of the round bale silage was summarized. The prospect of application and popularization in China was analyzed. Suggestions were made for providing some references to the development of the round bale silage.
