The straw is a general term of stem and leaf parts of mature crops, generally refers to the residual parts of wheat, rice, corn, potatoes, rape, cotton, sugarcane and other crops (generally coarse grain) after seeds are harvested, is rich in nitrogen, phosphorus, potassium, calcium, magnesium, organic matters and the like, and is a multipurpose renewable biological resource. The use of modern chemical fertilizers greatly reduces the agricultural requirements on the fertilizers made from straws, and the treatment of the straws becomes a difficult problem. If the straws are not processed in time, the sowing of the sowed crops can be influenced. Several kinds of straw treatment methods exist in the prior art, and all have the problems of environmental pollution and low efficiency: (1) and (5) burning the straws. Smoke generated by burning straws causes the reduction of air visibility, and directly influences the normal operation of roads, civil aviation, railways and other traffic; (2) plant fibers such as straws are used as raw materials, and a chemical pulping method is adopted for papermaking.

For the technical problem of pulping, the pulping technology of 'biological enzyme decomposition and separation of fiber' is researched at home and abroad, but the industrial mass production of paper pulp capable of realizing 'biological enzyme decomposition and separation of fiber' is still unavailable up to now. The difficulty of realizing industrial mass production of paper pulp by 'decomposing and separating fiber by biological enzyme' is as follows: (1) the process requirement is very complex, and the working procedures are many; (2) the process conditions are very high. Biological bacteria and enzyme preparations have particularly high requirements on the activity conditions; (3) the difficulty of the straw fiber stripping technology is high, so that the large-scale temperature control and pH value regulation and control of the straw fiber are difficult to carry out.
