Composite rice straw silage special additive agent

Abstract

The invention provides a special additive for silo of composite rice straws and a preparation method thereof; the method comprises the following steps: 20g to 40g of fresh green plants is added with 100g to 200g of sterile distilled water, and the obtained mixture is ground and stirred fully in a mixing stirrer and is filtered with sterile gauze so as to obtain green sap; the green sap carries out anaerobic fermentation for 48 hours at the temperature of 30 DEG C, then the fermentation liquid is diluted by 20 times, vacuumized, cooled and dried and then the fermentation liquid of the green sap is obtained; and the fermentation liquid of the green sap and dehydrogenation sodium acetate are mixed according to the proportion of 100 : 1(V / W) so as to obtain the special additive for silo of composite rice straws of the invention. The product of the invention prepares the spray usage of silo additives prepared according to the water content of rice straws in the silo material (use spraying equipment), can realize silo of rice straws of the entire plant on a large scale, can guarantee that the quality of the silo can reach higher level more than one grade (evaluation standard for international silo quality) and improves the aerobic stability of the silo greatly so as to avoid the secondary fermentation loss of hollow rice straws.

Description

technical field [0001] The invention relates to an additive, in particular to a special silage additive capable of promoting rice straw fermentation and improving the quality of rice straw silage. Background technique [0002] At present, there are many kinds of silage additives, which can be divided into four categories according to the purpose and effect of use: fermentation accelerators, fermentation inhibitors, aerobic spoilage bacteria inhibitors and nutritional additives. Its purpose is to promote lactic acid fermentation, inhibit bad fermentation, control aerobic deterioration and improve the nutritional value of silage. my country is rich in rice straw resources, and using rice straw silage as ruminant feed has very important social, ecological and economic significance for widening the source of silage, solving the problem of insufficient high-quality roughage, protecting the environment and promoting the sustainable development of animal husbandry. However, the ke...

Problems solved by technology

However, the key technology limiting rice straw silage is the lack of special silage additives for rice straw silage, because rice belongs to aquatic plants, and the content of lactic acid bacteria attached after harvesting does not meet the requirements of silage fermentation, and rice straw is harvested at the mature stage, its special The vascular bundle structure makes rice straw silage not easy to compact and prone to spoilage in the late stage of fermentation. Therefore, the key to the success of rice straw silage lies in the use of special silage additives to solve technical problems such as insufficient lactic acid bacteria content and anaerobic difficulties.

At present, Japan has successfully developed rice straw silage additives. Its main component is lactic acid bacteria preparations. Although it can promote the fermentation of silage, the disadvantage is that it has a single effect and can only promote silage fermentation, and cannot guarantee the stable and long-lasting quality of silage in the process of silage utilization. , and the production process is complicated, the price is expensive, it is difficult for general production units to accept, and the adaptability and effect of domestic silage raw material production and environment have yet to be confirmed
