Rice Genomics and Genetics 2025, Vol.16, No.4, 180-198 http://cropscipublisher.com/index.php/rgg 196 transformed into excellent varieties that are suitable for the local area and matched with a scientific planting system, a new path of improving the quality and efficiency of grain production and being friendly to resources and the environment can be found. While promoting new varieties, the Dahao Village Demonstration Base actively explores ecological planting models, providing a typical example for the sustainable development of regional agriculture. Its significance is reflected in the following aspects: First, it promotes the integrated innovation of agronomic measures and realizes the mechanization, intelligence and standardization of the whole process of rice planting. From seedling raising, transplanting to fertilization and prevention and control, the base adopts advanced agricultural machinery and technology, such as stacked tray seedling raising machine, side deep fertilizer machine, digital insect monitoring and reporting, etc. This greatly improves labor productivity, attracts more new business entities to participate in grain production, and also provides the possibility for large-scale planting. Second, it reduces agricultural non-point source pollution and production costs, and realizes efficient resource utilization. Through controlled-release fertilizer nitrogen reduction, efficient water management and green prevention and control, nitrogen leaching and pesticide residues in the base rice fields are significantly reduced, and the input of chemical fertilizers and pesticides per kilogram of grain is more than 15% lower than that of conventional planting. These measures reduce environmental load and maintain the ecological balance of farmland. At the same time, due to the reduction of chemical input, the total production cost has decreased, and the increase in yield has brought higher returns, forming a win-win situation for economy and ecology. Third, it improves the quality and market competitiveness of agricultural products. Rice produced under the ecological cultivation model is safer and higher quality due to the small amount of chemical pesticides and fertilizers, which meets the demand of modern consumers for green food. The "Jiashan Fragrant Rice" rice produced by the demonstration base has a significant premium in the market, and its brand value is prominent. This shows that ecological planting is not only an environmental need, but also driven by significant economic benefits. Fourth, it has accumulated experience that can be promoted and replicated for the green development of agriculture. The Dahao Village model has a good demonstration and radiation effect, and surrounding areas have learned from it. Through on-site observation and technical training, many high-yield demonstration plots in Jiaxing City and even the Yangtze River Delta region have promoted similar planting models. This is of guiding significance for achieving green rice production in a larger range. In addition, the successful implementation of the ecological planting model also relies on multi-party collaboration: scientific research, promotion, cooperatives and large planting households form a joint force to jointly promote the implementation of technology. This provides inspiration for building a long-term mechanism for green development of agriculture. The practice of new varieties + ecological cultivation in Dahao Village, Jiashan, fully proves the feasibility and comprehensive benefits of developing green agriculture. Its experience shows us that in future agriculture, only by taking the path of "high yield, high quality, high efficiency, ecology and safety" can we achieve true agricultural modernization. The exploration of this base provides a realistic template for achieving this goal. Although the demonstration of this study has achieved remarkable results, there are still some issues that deserve in-depth research and practical improvement in order to further promote the green and efficient development of regional grain production. First, in terms of new variety selection and breeding, we should continue to strengthen the cultivation of high-yield and high-quality varieties with multiple resistance. In particular, in view of the shortcomings of some new varieties that are not resistant to insects and have limited room for quality improvement, future breeding should make comprehensive use of molecular marker-assisted breeding, new gene discovery and gene editing technologies to cultivate rice varieties that are high-yield, widely adaptable, high-quality and multi-resistant. For example, it is possible to consider introducing anti-planthopper genes and high-temperature stable fruiting genes to cope with the increasingly severe biological and climatic adversity challenges. Secondly, in terms of cultivation technology, it is necessary to further improve the precise cultivation mode of different types of varieties. Although this demonstration summarizes some experience, the optimal planting density, fertilizer and water management schemes of different varieties can still be refined through field trials. It is recommended to establish a cultivation mode optimization test for the main promoted varieties,
