华农首席科学家罗利军：节水抗旱稻让农民种田有动力

Core Viewpoint - The introduction of drought-resistant and water-saving rice varieties is transforming previously abandoned farmland in Guangdong into productive agricultural land, providing new solutions for food security and sustainable farming practices [4][5][39]. Group 1: Agricultural Innovation - The drought-resistant rice variety has achieved a yield of 611.9 kg per mu, surprising local farmers [4][39]. - This innovation addresses the issue of abandoned farmland in Guangdong, with the potential to expand arable land [5][39]. - The research team has integrated drought-resistant traits into high-quality rice varieties, marking a significant breakthrough in agricultural science [6][19]. Group 2: Environmental Impact - The drought-resistant rice can save 50% of water and reduce carbon emissions by 90% [11][16]. - It can be cultivated in various terrains, including dry and hilly areas, without the need for flooding or transplanting [12][16]. - The rice variety has shown resilience against flooding, maintaining good growth even after severe waterlogging [42][46]. Group 3: Economic Viability - The simplicity of planting and stable yields significantly reduce labor costs for farmers [55][59]. - In areas like Huizhou, farmers can achieve a net profit of over 600 yuan per mu from cultivating this rice [60][61]. - The "Drought-Resistant 73" variety has been recognized for its quality, competing well in the market [61][62]. Group 4: Strategic Goals - The research team aims to increase rice planting area by 100 million mu and produce an additional 50 billion kg of rice while reducing irrigation water usage and carbon emissions by 20 billion kg each [66][68].
