山东省主要农作物秸秆资源评估及肥料化利用经济效益分析

Evaluation of Main Crop Straw Resources and Economic Benefit Analysis of Fertilizer Utilization in Shandong Province

为解决我国农业生产日益增长的肥料需求以及农作物秸秆处理难题,以山东省为例探究秸秆肥料化利用所产生的经济效益;通过统计2016年山东省17个地级市农作物的种植情况,结合相关文献,概算出山东省农作物秸秆资源量,评估秸秆肥料化利用潜力。结果表明,山东省2016年秸秆资源总量为5 067. 51万吨,肥料化处理后可折算73. 08万吨尿素、38. 49万吨过磷酸钙和89. 85万吨硫酸钾,产生的经济效益可达43. 24亿元。秸秆肥料化利用不仅创造了巨大的经济效益与社会价值,而且也避免了秸秆资源不合理利用对于大气环境的污染,符合国家的可持续发展战略。

In order to solve the problems of growing fertilizer demand in the process of agricultural production and crop straw treatment in China,the economic benefits of straw fertilizer utilization were explored by taking Shandong Province as an example.Through the statistic data of crop planting in17cities of Shandong Province in2016and the related literatures,the crop straw resources in Shandong Province were estimated and the potential of straw fertilizer utilization was evaluated to provide references for promoting the utilization of straw resources.The results showed that the total amount of straw resources in Shandong in2016was50675.1thousand tons.After fertilizer treatment,it could replace730.8thousand tons of urea,384.9thousand tons of Ca(H2PO4)2and898.5thousand tons of K2SO4,which could bring the economic benefits as4.324billion yuan.The straw fertilizer utilization could not only creat huge economic and social value,but also avoid the pollution of unreasonable utilization of straw resources to the atmosphere,so it is in line with the national sustainable development strategy.
