水稻大面积提产增效技术集成创新与应用
Rice Yield and Efficiency Large-Scale Improvement Technologies Integration Innovation and Application——Taking Guangde as an Example
摘要
Abstract
In response to the current bottleneck in large-scale yield improvement of rice in China,the China National Rice Research Institute has closely aligned with the strategy of"storing grain through technology"and systematically carried out technology integration and demonstration for enhancing rice yield and efficiency over large areas,using the"county-wide initiative"promotion as a leverage point.During the course of this work,we have integrated and innovated a comprehensive,all-element technological integration model termed"precision drilling for strong seedling cultivation and fixed-rate mechanical transplanting".This model is founded on the selection of high-quality and high-yield rice varieties,with precision drilling for robust seedling cultivation and quantitative mechanical transplanting of basic seedling numbers as its core technologies.It is supplemented by a series of supporting technologies,including the construction of fertile plow layers,precision and efficient fertilization,scientific matching of irrigation and drainage facilities,and comprehensive pest and disease control.In 2025,large-scale field trials conducted in Guangde City,Anhui Province,demonstrated a significant yield increase of over 20％in the 10,000-mu(667 m2)demonstration plots through the extensive promotion of indic a-japonic a hybrid rice varieties and precision drilling-strong seedling mechanical transplanting techniques.The study further confirms that timely variety updates and integrated technology applications are effective means to drive large-scale yield and efficiency improvements.However,issues such as the improvement of medium-and low-yielding fields,effective disease control in certain regions,scientific management of weeds in direct-seeded rice,and the high cost of mechanical transplanting faced by small-scale farmers remain to be addressed.In the future,it is necessary to further refine the socialized service system,implement supporting measures for the improvement of medium-and low-yielding fields,and integrate high-yield technologies for different planting methods to promote a comprehensive increase in large-scale rice yields.关键词
