土壤配备“医生” 污水变成“财富”

Core Viewpoint - The establishment of the "Organic Agricultural Technology Institute" in Lingqiu County, Shanxi Province, is significantly enhancing agricultural productivity and farmer income through the use of agricultural enzymes and innovative farming techniques [1][2][3]. Group 1: Agricultural Innovation - The "Organic Agricultural Technology Institute" focuses on a "low-cost, high-quality county-level organic agriculture engineering technology system" that integrates scientific research with practical farming [1]. - The enzyme planting demonstration area utilizes a "plant-animal-microbe" organic planting system developed by China Agricultural University, which transforms kitchen waste and agricultural by-products into beneficial microbial strains for high-efficiency fertilizers [2]. - The use of enzymes has led to a 3%-4% increase in protein content in millet and a 55.7%-137.5% increase in lycopene content in tomatoes, showcasing the effectiveness of this approach [2]. Group 2: Economic Impact - The cost of fertilizers for millet cultivation has decreased from 300 yuan to 110 yuan per mu, while the selling price of millet has risen from 2 yuan to 3.5 yuan per jin, resulting in a profit increase of 768 yuan per mu compared to traditional methods [2]. - The implementation of the "toilet revolution + organic dry farming" project has transformed waste management in rural areas, producing 1714 tons of organic fertilizer annually and saving significant amounts of irrigation water [4]. - The operational cost of the waste treatment facility is only 53,900 yuan per year, generating direct economic benefits of 165,000 yuan and boosting related industries by over 5 million yuan [4]. Group 3: Sustainable Development - The agricultural enzymes not only serve as fertilizers but also act as "soil doctors," enhancing soil health and promoting sustainable farming practices [3]. - The technology has been successfully promoted to neighboring counties, with nearly 400 demonstration households and over 2000 mu of land benefiting from the enzyme planting method [3]. - The team aims to further develop pathways for organic agriculture, focusing on waste classification and the application of agricultural enzymes to create replicable and scalable solutions for nationwide organic farming [6].
