我国积极探索区域盐碱耕地治理模式 综合利用，盐碱地变丰产田

Core Viewpoint - China is actively exploring regional governance models for saline-alkali land management, aiming to enhance agricultural productivity and ecological sustainability through innovative techniques and practices [1][2]. Group 1: Saline-Alkali Land Utilization - The "14th Five-Year Plan" emphasizes high-quality construction of farmland and comprehensive utilization of saline-alkali land to improve soil quality [1]. - A recent report highlights over 40 innovative achievements in biological breeding, productivity enhancement, and ecological utilization of saline-alkali land [2]. - Various technical models have been developed, such as the "dry sowing and wet harvesting" method for cotton in the Northwest Oasis region, promoting efficient use of resources [2]. Group 2: Agricultural Practices and Crop Management - In Jiangsu's coastal saline-alkali areas, a rotation planting model has been implemented, achieving a 20% increase in soil organic matter and maintaining soil salinity below 2‰ [2]. - The report advocates for a differentiated approach to land use, promoting specific crops based on the salinity level of the land [4]. - Successful cultivation of saline-alkali resistant crops has been reported, including varieties like "Jiyang 12" with a yield of 317.9 kg per mu [5]. Group 3: Challenges and Solutions - Current challenges include issues with irrigation practices, freshwater resource shortages, and mismatched salt control technologies [3]. - The report stresses the importance of establishing efficient drainage systems and a dynamic monitoring network for soil salinity [3]. Group 4: Development of Specialty Agriculture - The development of specialty agriculture in saline-alkali areas is encouraged, focusing on high-value products and brand recognition [5]. - The report indicates that unique functional components in saline-alkali products can enhance their market value [4]. - A variety of specialty products have been developed, including deep-processed items from saline-alkali crops, significantly increasing industry value [4].
