摘要： As a major agricultural country, China is also one of the world’s most abundant sources of crop straw, with production expected to reach 900 million tons by 2025. As an agricultural by-product, straw has been widely regarded as a potential renewable resource. It is rich in organic matter and essential nutrients such as nitrogen (N), phosphorus (P), and potassium (K), playing a critical role in global carbon and nitrogen cycles, agricultural productivity, and green environmental development. The efficient and rational utilization of straw can not only meet the resource demands supporting economic growth but also contribute to environmental protection and sustainable social development in China. By closely integrating comprehensive straw utilization with the annual key tasks of agriculture, rural areas, and farmers, the focus remains on prioritizing agricultural applications while adopting diversified measures. The efforts aim to improve straw utilization methods, strengthen technological support, explore replicable and sustainable industrial development models, and establish efficient utilization mechanisms to enhance the quality of agricultural straw use. To fully leverage the agricultural potential of straw, numerous technologies and equipment for straw utilization in agriculture have been developed in recent years, including straw harvesting and collecting equipment, straw crushing and returning-to-field equipment, full-straw seeding anti-clogging technology, combined straw and green manure returning-to-field equipment, and specialized straw seedling-raising equipment. Nevertheless, many challenges remain to be addressed, including bridging the equipment gap in mechanized processing, overcoming technical bottlenecks in resource conversion, and filling the lack of agronomy-adapted technologies. Therefore, this paper aims to provide a comprehensive and critical analysis of present straw utilization technology and equipment in agriculture, discussing their potential benefits, limitations, and challenges, as well as future prospects and directions. This study provides insights from the perspective of key technologies and equipment to strengthen technological research, enhance straw’s agricultural potential, and explore green circular economy models in agriculture. By leveraging innovation in science and technology, it aims to ensure food security and improve grain production capacity.
