The invention relates to the technical field of straw papermaking research, and discloses a method for increasing the wheat straw papermaking yield. By researching the structure of wheat straw and theperformance of paper pulp, the problems of low utilization rate, insufficient strength and the like of wheat straw in papermaking production in the prior art are solved. According to the method, firstly, pretreatment is carried out on wheat straw, the protection and utilization of cellulose and hemicellulose components in the straw are obviously improved, the pretreated modified straw powder anda prepared reinforcing agent are subjected to pulping together, straw cell walls can be protected from being damaged, the structure is compact and resistant to degradation, the yield of paper pulp treated by the reinforcing agent is remarkably increased, the comprehensive performance of paper products can be effectively enhanced, and the tensile strength, bursting strength and weather resistance of the prepared paper are remarkably improved.
