摘要
我国秸秆资源丰富,但胡乱丢弃、无控焚烧、直接还田和加工粗饲料等传统的处理方式存在着"三低一重"的缺点,即秸秆利用率低、转化率低、经济效益低、环境污染严重。本文介绍了秸秆综合利用技术的最新进展,包括腐熟还田技术、饲料转化技术、能源化技术及秸秆在工业上的各种应用。认为农作物秸秆的综合利用是保护生态环境、节约可再生资源的需要,也是缓解农村饲料、肥料、燃料和工业原料的紧张状况、促进农业可持续发展的要求。
Crop straw resources are abundant in China, however, the traditional treatment patterns such as abandoning litterly, burning wildly, returning to the soil directly and processing as raw forage etc. are characterized by low utilization ratio, less conversion ratio, poor economic benefit and severe environmental pollution. In the article, the latest comprehensive utilization technique progress of crop straws are introduced, which includes rapid compost techniques, effective forage techniques, energization techniques and all kinds of straw applications in industries. It is concluded that comprehensive utilization of crop straws is not only the urgent measure for protecting ecological environment and saving the reproducible resources, but also can relieve the intense situation of rural forage, fertilizer, fuel and industrial raw material, and promote the sustainable development of agriculture as well.
