Rice straw ensiling additive based on orthogonal test method optimization design and optimizing method

The invention belongs to the technical field of feed ensiling, and relates to a rice straw ensiling additive based on orthogonal test method optimization design and an optimizing method. The method includes the following steps of firstly, selecting the type of ensiling bacteria, the type of cellulose decomposition bacteria or enzymes and the type of carbon source substances as test factors, and determining evaluating indexes; secondly, selecting a three-factor three-level orthogonal table (L9(33)) according to the levels of all the factors to arrange test combinations and conducting a test; thirdly, analyzing test data through a comprehensive balancing method, and determining the optimal combination scheme, wherein the additive is composed of the ensiling bacteria, the cellulose decomposition bacteria or enzymes and the carbon source substances. The additive can better improve the ensiling efficiency, is convenient to use, reduces the cost, is easy to operate, has the advantages of being critical, neat and co
