Description

Fermentation of plant straws agent and its application method suitable for cold district
Technical field
The present invention relates to fermentation technical field, and in particular to a kind of fermentation of plant straws agent suitable for cold district and its Application method.
Background technology
In recent years, agricultural crop straw turns into the new source of Rural Plane Source Pollution.The annual summer harvest and when the autumn and winter, always there is a large amount of The stalk such as wheat, corn burned in field, generate a large amount of heavy smogs, not only the bottleneck as rural environmental protection is asked Topic, or even as the arch-criminal for bringing disaster to urban environment.According to the relevent statistics, China can be generated more than 700,000,000 every year as large agricultural country Ton stalk, as " use is little " but " discarded object " that must dispose.In the case, handled, just gone out by peasant completely The phenomenon of a large amount of burnings is showed.
It is that the synthesis of agricultural crop straw is opened by scientific progress and creation particularly in developed country in terms of abroad instance Hair using have found multiple use, except it is traditional straw chopping and returning is made into organic fertilizer in addition to, also walked out straw feed, stalk The new approach such as vaporization, stalk fermentation, straw ethanol, stalk building materials, substantially increase stalk utilizes value and utilization rate, is worth me Use for reference.
Stalk fermentation technology is to utilize biogas fermentation device, and the stalk of crushing is carried out into anaerobic fermentation processing, the natural pond of production Gas is used for cooking and illumination, and biogas residue and biogas slurry are used for agricultural production.In the cold district such as north or southern winter, due to temperature Low to cause fermentation efficiency low, fermentation time length is, it is necessary to which special leavening accelerates fermenting speed, raising fermentation efficiency.
The content of the invention
It is an object of the invention to provide a kind of fermentation of plant straws agent suitable for cold district and its application method, soon Speed improves course of fermentation, shortens fermentation period.
The technical scheme that uses to achieve these goals of the present invention for:
