广州市协作办公室赴华南农大调研节水抗旱稻，达成合作推广意向

Core Insights - The Guangzhou Collaborative Office organized a research visit to South China Agricultural University to explore the promotion of drought-resistant rice, aiming to drive agricultural green transformation through technological innovation and contribute to rural revitalization and food security [2][3][4]. Group 1: Technological Innovation - The research team presented a report on "Drought-Resistant Rice Theory and Practice," highlighting four major challenges in rice production: reduced arable land, water resource scarcity, non-point source pollution, and carbon emissions [9][10]. - The development and application of drought-resistant rice are seen as key measures to address these challenges, with a focus on integrating high-yield characteristics of modern rice with drought resistance [11][12]. - Drought-resistant rice varieties can save over 50% water compared to traditional rice while maintaining stable yields of 500-600 kg per mu, demonstrating resilience to drought conditions [15][16]. Group 2: Local Adaptation and Practices - The team shared successful experiences in promoting drought-resistant rice in Guangdong, including the use of biodegradable film for planting in challenging conditions, which has led to replicable solutions [23][24]. - In Meizhou, drought-resistant rice achieved yields exceeding 450 kg per mu, significantly above the provincial average, showcasing its adaptability to marginal lands [25][27]. - The team is collaborating with Fujian to explore "dry transplanting" technology for high-yield cultivation in sandy soils, with the rice variety also being promoted in saline-alkali areas and drought regions globally [28][29][30]. Group 3: Collaborative Efforts and Future Goals - Discussions during the meeting led to a preliminary agreement on promoting drought-resistant rice, focusing on practical issues such as planting techniques and market strategies [34][36]. - The South China Agricultural University will provide technical support and assist in developing standardized planting guidelines, ensuring effective implementation of technological advancements [40][41]. - The team aims to achieve a national increase of 50 billion kg of grain and expand the planting area by 10 million mu, while promoting 5 million mu internationally, positioning Guangdong's practices as a model for nationwide application [42][43][44].
