Abstract: This paper, based on on site survey and annual statistics, reviews the use situation of straw, uses straw/grain ratio to estimate the total straw resource, discusses its trend during 20062013, and studies the potential of feeding cattle. Straw is quite low in using as a resource. In the study area the total straw resource is estimated to be at 691.5kt, amounting to 412.9 kt in standard coal, 250 million cubic meters in methane, with potential to use. Issues include irrational use structure and low use quality. The straw resource can feed 533.3k cattle at a straw/feeding ration of 35%, indicating a good outlook in feeding cattle. This paper presents suggestions in raising straw use and potential from educating farmers in their knowledge of straw resource value, increasing the allowance of enterprises and farmers using straw, intensifying technical innovation and application, boosting the industrialization and establishing a cycle of using straw resource.

摘要： 以区域农户实地调查和年鉴数据为基础，概述农作物秸秆资源化利用现状，采用草谷比法估算研究区秸秆资源总量，描述2006—2013年各类秸秆资源价值变化趋势，并估算秸秆养牛的发展潜力，分析秸秆资源化利用程度低等问题。研究结果表明：研究区秸秆资源总量为69.15万t，折合标准煤 41.29万t，折合沼气量25 014.64万m3，其秸秆资源存量大，存在较大利用潜力；秸秆资源综合利用结构不尽合理，资源化利用质量偏低；若按秸秆饲用率35%计算，研究区可养殖肉牛约为53.33万头，农作物秸秆养牛前景可观。基于此，本文提出以下几点提高秸秆资源利用程度及其潜力的建议：加强宣传教育，提高农户对秸秆资源价值认知度；加大对秸秆资源利用行为的企业和农户财政补贴和奖励力度；强化秸秆资源综合利用技术创新和应用，实行示范和推广；加快秸秆产业化发展，建立以效益为纽带的秸秆资源化循环模式。
