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

Abstract

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 comparable, can accelerate the ensiling rice straw ripening time and has the ordinary ensiling mature period of 60 days, and by means of the additive, the ensiling period can beshortened to be 30 days.

Description

technical field [0001] The invention belongs to the technical field of feed silage, and relates to a rice straw silage additive preparation and an optimization method based on the optimization design of an orthogonal test method. Background technique [0002] Rice straw is the largest crop straw in my country. In 2009, the total output of rice straw in my country reached 184.4304 million tons, and the annual output accounted for more than 1 / 5 of the total crop straw output in the country. At present, rice straw has been vigorously developed and utilized for power generation and biogas production, especially in the aspect of livestock breeding, which has made great breakthroughs. However, according to statistics, at present, 20% of straws are still wasted every year because they are not properly and fully utilized, and there is also the problem of environmental pollution. [0003] Rice straw contains a large amount of crude fiber carbohydrates, which can be used as an import...
