Core Insights - The article highlights the significant progress in soybean production in China, with over 50% of the autumn grain harvest completed by October 10, including 55% of soybean harvest [1][2]. Group 1: Soybean Production and Technology - In Heilongjiang Province, soybean yield has reached 393.98 jin per mu (approximately 262.65 kg) due to new technologies and varieties [3]. - Farmers have reported a yield increase from previous levels of 350 jin per mu (approximately 233.33 kg) to higher levels this year, attributed to techniques such as dense planting and the use of microbial agents [5]. - A new nitrogen-fixing technology developed by the Chinese Academy of Agricultural Sciences has been implemented, resulting in an average income increase of about 400 yuan per mu [7]. Group 2: Agricultural Practices and Innovations - High-yield, drought-resistant soybean varieties are being promoted across major production areas, with demonstration zones achieving yields exceeding 300 kg per mu [9]. - The number of counties implementing large-scale yield improvements has reached 100, focusing on key regions like Heilongjiang and Inner Mongolia [11]. Group 3: Overall Production Trends - China's soybean planting area has stabilized at over 150 million mu, with production surpassing 20 million tons for the first time in 2022, reaching 20.65 million tons last year [13]. - The self-sufficiency rate for soybeans has increased by 4 percentage points since 2020 [13].
