施用有机肥已经引起世界各国普遍的关注。土壤肥力是土壤质地的特征,它与有机物质紧密关联、增施有机肥料是农作物稳产高产、培肥地力、增强农业后劲的关键,也是充分利用现有肥料资源的重要内容。1977年和1978年连续两年在瑞士召开了国际有机农业会议,着重探讨了有机农业和现代科学技术相结合以促进生态平衡的问题。 The application of organic fertilizer has aroused the universal attention of all countries in the world. Soil fertility is a characteristic of soil texture. It is closely related to organic matter. Adding organic fertilizer is the key to stabilizing and yielding crops, fertilizing fertility and enhancing agricultural stamina. It is also an important part of making full use of existing fertilizer resources. In 1977 and 1978, for two consecutive years, the International Conference of Organic Agriculture was held in Switzerland, focusing on the issue of integrating organic agriculture and modern science and technology to promote ecological balance.
