Embodiment Construction
[0014] In order to better understand the present invention, the present invention will be described in detail below in conjunction with specific examples, and those not described in detail shall be referred to as prior art in the field. The protection scope of the present invention is not only limited to the scope that embodiment represents:
[0015] The preparation method of the plant straw plate of the present invention comprises the following steps:
[0016] A. After the solid-liquid separation of the fermentation residues in large and medium-sized biogas projects that use crop straw as the fermentation raw material, the straw biogas residue is obtained, and the biogas residue powder with a particle size of 2.0 mm is crushed by an ordinary crusher, and dried on the field. Make its water content less than 40%, to obtain 100kg of straw biogas residue powder;
[0017] B. After measurement, the pH value of straw biogas residue is 7.22, which is 1.02 lower than the pH value of ...
