Abstract：Crop straw feed utilization is an important way to promote the goal of'double carbon'and the green transformation of agriculture.At present,the technical system for the'five utilization modes'(fertilization,feedization,fuelization,substratization,materialization)is becoming more and more mature,but the biological conversion still faces the bottleneck of low degradation efficiency,poor process stability,and poor economic benefits.To systematically sort out the practical effects of biotransformation technology in the application of straw feed and to explore the core issues in the process of industrialization,based on the relevant literature at home and abroad,the biotransformation technology and its regulatory mechanism in the application of straw feed were focused on,and the synergistic effects of three mainstream technologies,microbial fermentation,enzymatic pretreatment,and insect body transformation,were analyzed.On this basis,the main challenges faced in the current large-scale popularization and application were summarized,and the future development direction was proposed from the two dimensions of technological innovation and policy support in order to provide a theoretical basis and practical reference for the efficient utilization of crop straw feed and the sustainable development of animal husbandry in China.
