亩产611.9公斤！肇庆鼎湖沙浦基地节水抗旱稻测产告捷

Core Viewpoint - The successful harvest of water-saving and drought-resistant rice at the Sha Pu base in Zhaoqing demonstrates the potential of this new rice variety to enhance agricultural productivity and address issues related to abandoned land and ecological restoration [2][21]. Group 1: Harvest Results - The average yield of the water-saving and drought-resistant rice was measured at 611.9 kilograms per mu, showcasing its strong resilience and stable production [4][5]. - The trial involved 40 mu of land, marking the first harvest of this rice variety [2][22]. Group 2: Agricultural Practices - The rice variety used, Drought-Resistant 73, was sown at a rate of 2 kilograms per mu and is particularly suited for planting in previously abandoned land due to its strong drought resistance and ability to thrive in poor soil conditions [8][12]. - The cultivation method employed includes "dry direct seeding" and biodegradable film, relying on natural rainfall throughout the growth period [9][10]. Group 3: Environmental Impact - The water-saving and drought-resistant rice significantly reduces irrigation water usage, minimizes non-point source pollution and methane emissions, and lowers labor costs [15][17]. - This new rice variety is seen as a key solution for revitalizing abandoned and saline-alkali lands, contributing to national food security [21][23]. Group 4: Future Development - The South China Agricultural University plans to further optimize planting techniques and expand demonstration projects to promote the long-term development of water-saving and drought-resistant rice in Zhaoqing and Guangdong [24]. - This agricultural innovation is positioned as a benchmark for agricultural transformation, offering a "Chinese solution" for global food security challenges [25][26].
