是应用灌装机将切碎的青饲物料以较高密度，快速、水平压入专用拉伸膜袋（直径2.0-2.5米，长30-45米）中，利用拉伸膜袋的阻气、遮光功能，为乳酸菌提供更佳的发酵环境来进行青贮的技术
一、袋贮技术机械配备及工艺流程
1.配套机械设备有:青饲收获机、青饲拉运车、喂料平台、袋式灌装机及相应的大中型轮式拖拉机作为配套动力。
2.工艺流程:青饲收获→拉运→卸料→灌装→封存
二、袋贮技术相对于窑贮有以下优势
1.可以青贮多类型禾本科饲草及豆科牧草，如玉米、高粱、小黑麦、紫花苜蓿等。
2.青贮损失小:避免了窑贮霉变、渗液和二次发酵造成的损失，其损失不超过1%。
3.青贮质量可靠:袋内青贮料与外界空气完全隔绝，密度高（窑贮0.5t/m3，袋贮可达到0.65t/ m3），均匀性好，袋内青贮物料可以充分进行乳酸发酵，得到质量优良的青贮料。
4.适应性强，可雨季作业。
5.饲喂效果好:用袋贮料饲喂家畜，畜产品产量和品质均有提高，综合经济效益提高10%-15%。
三、相关参数
1.机具的一些具体参数:
青贮饲料装袋机

Is the application of filling machine will be chopped green feeding material with higher density, fast, horizontal pressure into the special tensile membrane bags (diameter 2.0-2.5 meters long, 30 to 45 meters), the use of tensile membrane bag of resistance gas, window function, provide better for lactic acid bacteria fermentation environment for silage technology
A, bags storage technology equipped with mechanical and process flow
1. The necessary mechanical equipment are: green forage harvester, green feeding roping car, feeding platform, bag filling machine and the corresponding large and medium-sized wheeled tractor as supporting power.
2. Process: green feeding harvest - roping - discharge - filling and storage
Second, the bag storage technology relative to kiln storage has the following advantages
1. Can silage multi-type gramineous forage grass and bird 's-foot, such as corn, sorghum, small rye, alfalfa, etc.
2. Silage losses small: avoid the kiln storage mildew, seepage and the loss caused by secondary fermentation, the loss is more than 1%.
3. Silage quality reliable: bag silage and outside air complete isolation, high density (kiln storage 0.5 t/m3, bag storage can achieve 0.65 t/m3), uniformity is good, bag silage material can make full malolactic fermentation, get quality silage.
4. Has strong adaptability and can work the rainy season.
5. Feeding effect is good: use bag storage material feeding livestock, animal product yield and quality were increased, the comprehensive economic benefit increased by 10% - 15%.
Three, the relevant parameters
1. Machines some specific parameters:
Silage bagging machine
(1) the use of the machine
Silage bagging machine is a kind of special used for silage special filling equipment, be applicable to the moisture content at 50% ~ 65% of the chopped forage grass (such as maize straw, etc.) bag silage.
