再生稻如何提升种粮质效（新知）

Core Viewpoint - The development of regenerative rice is becoming a key player in stabilizing grain production and increasing farmers' income, supported by modern agricultural technology [1][3]. Group 1: Production and Economic Benefits - Regenerative rice cultivation allows for two harvests from one planting, significantly increasing productivity with average yields of 600 kg per mu in Anhui and 719.3 kg per mu in Hunan [1][2]. - The cultivation method reduces production costs by 400-500 yuan per mu, as it eliminates the need for re-seeding and reduces the use of fertilizers and pesticides [1][2]. - The quality of rice produced in the second season is often superior due to favorable growing conditions, leading to higher market prices [2]. Group 2: Technological Innovations and Challenges - The main challenge for the expansion of regenerative rice is the damage caused by traditional harvesting machinery, which can crush the dormant buds necessary for regeneration [2]. - Innovations such as narrow-track, wide-cut harvesting machines and the "wide-narrow row planting model" are being developed to minimize damage and improve yields [2]. Group 3: Policy and Future Development - The Ministry of Agriculture aims to increase the area of regenerative rice by approximately 10 million mu by 2030, emphasizing the integration of good seeds and farming practices [3]. - Technological advancements, including precision agriculture tools, are crucial for enhancing production efficiency and ensuring food security [3]. - The promotion of hybrid rice in over 20 African countries reflects China's commitment to agricultural modernization and international cooperation [3].
