Currently, the following methods are mainly used for storing silage:

1. stacking and storing: the method is to directly pile the chopped straws on the ground for ensiling. The advantages of heap storage are low cost and low investment; the defects are inconvenient taking and use and higher compaction difficulty.

2. And (4) cellaring: the method for ensiling the raw materials in the ensiling cellar is suitable for farms with a certain scale, and has the advantage of repeated use for many years with one investment; but the investment is large at one time, the requirement on the field is high, and the field suitable for building the ensilage cellar is obtained.

3. Bundling, enveloping and ensiling: the method comprises the steps of cutting the harvested raw materials, compacting and bundling the cut raw materials at high density by using a bundling machine, wrapping the cut raw materials by using a silage plastic stretching film, enabling the bundled and enveloped straw bundle to be in an optimal sealed fermentation environment, and finally completing the biochemical reaction of natural fermentation of lactic acid bacteria after 3-6 weeks. The bundling and wrapping silage is good in quality, long in storage time, convenient to store, take and transport, less in loss and waste, free of leakage and small in environmental influence.
