Core Viewpoint - The transformation of saline-alkali land into productive agricultural areas is crucial for ensuring national food and ecological security, with the establishment of a national saline plant garden in the Yellow River Delta being a key strategy for comprehensive utilization of saline-alkali land [1][5]. Group 1: Saline-Alkali Land Potential - China has approximately 150 million acres of saline-alkali land, with Shandong province accounting for nearly 9 million acres, primarily located in the Yellow River Delta [3]. - Saline plants are considered "pioneer plants" that can survive in high-salinity environments, improve soil quality, and serve as a genetic resource for salt-tolerant crop breeding [3][5]. Group 2: National Saline Plant Garden - The saline plant garden is viewed as an important carrier for the comprehensive utilization of saline-alkali land, with a historical context of previous attempts to establish such a facility being hindered by urban planning changes [5][7]. - The current "14th Five-Year Plan" emphasizes the need for strengthening the protection of black soil and the comprehensive utilization of saline-alkali land, indicating a timely opportunity for the re-establishment of the national saline plant garden [5][8]. Group 3: Innovation and Ecosystem Development - Shandong has made significant progress in the comprehensive utilization of saline-alkali land, including the establishment of a genetic resource bank for saline plants and a digital breeding accelerator for salt-tolerant plants [5][7]. - The proposed saline plant garden should evolve beyond traditional roles to become a fusion of national strategic technology and ecological economy, incorporating various functional zones for resource protection, technology demonstration, and industry incubation [7][8]. Group 4: Policy and Strategic Recommendations - Despite advancements, challenges remain in the construction of the saline plant garden, including low strategic positioning, insufficient collaborative innovation, and limited government investment [8]. - It is recommended that the national saline plant garden be included as a key project in the Shandong Province's ecological protection and high-quality development plan, with supportive policies and mechanisms established to facilitate its development [8].
