The invention relates to a method for preparing a
jerusalem artichoke straw micro-storage feed. The method comprises the following steps: (1) dissolving white
sugar into
clean water, adding
straw fermented live bacillus, and placing the obtained object for 1-2h at
room temperature so as to obtain resurrected
straw fermented live bacillus; (2) pouring the resurrected straw fermented live bacillus into
salt water, and uniformly stirring the obtained object so as to obtain a bacterium agent; (3)
cutting jerusalem artichoke straws into small sections with a length of 3-8cm, paving the small sections at the bottom of a pit, wherein the thickness of each layer of straws is 20-30cm; uniformly spraying the bacterium agent on each layer of straws, compacting the straws until the thickness of the straws is 40cm higher than the mouth of the pit; and at this moment, fully compacting the straws, uniformly sprinkling salt
powder on the upmost layer of straws, and after compacting the straws, covering a
plastic film on the straws; and finally, scattering straws with the thickness of 20-30cm on the
plastic film, and covering soil with the thickness of 15-20cm, and sealing the pit; and (4) 21-30 days later, when the
moisture content of
jerusalem artichoke straws is 60-70%, obtaining the jerusalem artichoke straw micro-storage feed. According to the method disclosed by the invention, the process is simple, the cost is low; obtained products are high in nutritional ingredients, high in digestibility, good in
palatability, and high in
food consumption.
