摘要
我国2000多年的历史证明:农业可以持续发展,从农业外部投入物质和能量,是现代化农业生产力突破性进展的重要特征。单靠化肥引起许多土壤问题,关系到人类健康,生产使用有机肥料是一项重要的社会产业,保证营养元素合理循环是农业生产持续发展的根本问题。
More than 2000-year history of agriculture in China has demonstrated that the grain yield could be sustained and the soil productivity could be maintained and gradually improved through recycling the nutrient elements and raising the efficiency of organic manure. The input of non-agricultural material and energy is a most effective way to increase the crop yield and is one of important characteristics of modern agriculture. But there is a tendency in some regions that the farmers prefer only chemical fertilizer. The long-term application of sole chemical fertilizers will cause many soil problems and exert a bad influence on crop quality and human health. Particular attention sould be given to the development, production and application of the organic manures, so as to solve the problem of organic manures, to improve soil properties and to develop sustainable agriculture.
