华北平原典型农区秸秆资源与利用——以河北省曲周县为例

Crop Straw Resources and Utilization in Typical Agricultural Region of North China Plain

采用入户调查、利用统计资料及查阅文献的方法,对河北省曲周县秸秆资源利用现状进行了分析。结果表明,曲周县秸秆资源丰富,2007年秸秆资源量为49.4万t,据估算能产生良好的社会、经济和生态效益;主要秸秆资源是小麦、玉米和棉花秸秆,三者占秸秆总资源量的97.7%;小麦、玉米秸秆主要的利用方式是秸秆还田,其秸秆还田率达96.47%以上,秸秆饲料化利用率较低;棉秆利用还应该进一步优化。根据存在的问题,提出可利用当地丰富的秸秆资源优势发展畜牧养殖业,走秸秆养殖-沼气-肥料高效循环农业生产道路,以高效利用农作物秸秆的建议。

The straw utilization status in Quzhou County of Hebei Province is analyzed by door-to-door investigation,statistical data and literature review.The results indicate that,The crop straw are very resourceful with 49.4 million ton produced in 2007 in this county,which is estimated that could produce good social,economic and ecological benefits;the straw resources mainly include wheat,maize and cotton straws,which take for 97.7% of the total straw resources;the wheat and maize straws are mainly returned into fields,and the returning rate of maize and wheat straws reaches above 96.47%,very few straws are used as feeds;the use of straws should be further optimized,and it is proposed that the straws resources can be adopted to develop animal husbandry,and go on a high-efficient agricultural production path of straw breeding-biogas-fertilizer.
