The invention relates to a straw bio-enzyme degradation aid in the technical field of straw degradation, which comprises the following components in percentage by weight: 8 to 10 percent of cellulase, 6 to 11 percent of lipase, 6 to 10 percent of alpha-1,4-glucose hydrolase, 4 to 10 percent of catalase, 6 to 20 percent of urea, 6 to 16 percent of magnesium sulfate, 8 to 15 percent of fatty alcohol-polyoxyethylene ether, 11 to 15 percent of alkylphenol polyoxyethylene ether OP and the balance of excipient. A degradation pulping process for the straw bio-enzyme degradation aid comprises the following steps of: cleaning straw, cutting into segments, putting the segments into a quick pulping machine, adding water and the straw bio-enzyme degradation aid, mixing uniformly, and heating to the temperature of between 50 and 60 DEG C in the quick pulping machine for rubbing to perform reaction for 1 to 1.5 hours; and adding hydrogen peroxide for bleaching, and when the whiteness is more than 70 percent which is required by International standard organization (ISO), stopping the reaction to obtain paper pulp. The degradation pulping process is non-pollution, thermophilic digestion is avoided, strong base and strong acid are not used, the requirement of environment-friendly pulping is met, waste water is not discharged during pulping, a large amount of water for production and energy canbe saved, the production cost is reduced, and the pulping speed is accelerated.
