变废为宝：科技赋能促增收 在丹朱镇西寺头村的丹西龙鑫现代农业产业园，中国农业大学开辟的有机实验田旁，数个近2米高的密 封塑料桶引人注目。掀开桶盖，酸甜气息扑面而来——这正是中国农业大学带来的"绿色方案"：利用残 次果蔬发酵制成的"农用酵素"。"这些桶里装的是滋养土地的'液体黄金'，是优质的有机肥料。"产业园 负责人李强说。 中国农业大学长子县暑期实践农酵小队队长王乐泉演示了技术核心：将残次果蔬等废弃物按红糖、废弃 物、水1:3:10的比例投入桶中，首月每日开盖排气，后续密封发酵两个月，三个月后即可获得富含有益 微生物、养分和有机酸的酵素液。这项技术通过微生物将废弃物转化为活性物质，实现循环再生。 中新网长治9月4日电 题：山西长子：校地合作深化 "农用酵素"技术赋能乡村振兴 作者 刘小红 魏慧梅 和红波 一头牵着高等学府，一头连着田间地头。自2021年山西长治长子县与中国农业大学开启校地合作以来， 双方以"农用酵素"技术为纽带，推动农业废弃物资源化利用，促进科研成果转化，将高校智慧转化为驱 动有机农业发展、赋能乡村振兴的强劲动能。 长子县与中国农业大学开启校地合作以来，双方以"农用酵素"技术为纽带，推动农业废 ...

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].
