省沿海集团盐碱地改良技术集成示范区小麦亩产达989.1斤

Core Insights - The Coastal Group's Changdong Land Improvement Project has achieved significant success in transforming saline-alkali land into productive farmland, with wheat yields averaging 989.1 jin per mu, setting a new record in Jiangsu province [1][3]. Group 1: Project Overview - The Changdong project is located in a typical coastal saline-alkali area, characterized by low fertility and high salinity levels, making it challenging for crop production [2]. - The project utilized a tailored approach involving collaboration with research institutions to develop a comprehensive soil improvement strategy [2]. Group 2: Agricultural Yield Improvements - In the 2023-2024 season, the project achieved rice yields of 1144 jin per mu, a 6% increase compared to conventional improvement areas, and rapeseed yields of 421.9 jin per mu, up nearly 30% [3]. - Despite adverse weather conditions in the 2024-2025 season, the project still recorded impressive yields, with rice at 1012 jin per mu (27.5% increase) and wheat at 989.1 jin per mu (13.8% increase) [3]. Group 3: Technological Advancements - The success of the Changdong project represents a breakthrough in technology for saline-alkali land management, establishing a comprehensive soil quality evaluation system and a targeted improvement model [4]. - The Coastal Group plans to standardize and disseminate these technological achievements for broader application in saline-alkali land improvement, aiming for an average yield increase of over 15% in future projects [4].
