江西省有机资源调查报告

通过调查湖口、南昌、上高、泰和、兴国、余江县有机资源及其利用状况,量化分析相应区域有机资源利用情况,以此为基础衡量江西省有机资源量及其利用现状,总结存在问题,并提出建议。结果显示2007～2008年江西省年均作物秸秆产量1764.6万t,作物秸秆直接还田31.8%,间接还田12.0%,燃烧还田52.5%,其它用途3.8%;绿肥种植面积53.33万hm2,占总耕地面积的25.1%,年产鲜草1237.2万t,其中直接还田85.6%,间接还田14.4%;人畜禽有机肥料年产9074万t,还田利用比例64.7%,流失35.3%;江西省直接还田、间接还田、燃烧还田和其它利用四种秸秆利用方式,养分回收占施肥量的比例分别为9.9%、10.1%、22.9%和4.6%。深入研究高效秸秆还田技术,扩大绿肥种植面积,开发新型有机肥综合利用模式,平衡利用有机肥资源,有效提升江西省整体农田质量是今后研究的重要发展方向。

Investigation Report of Organic Resources in Jiangxi Province

The investigation of organic resources was conducted in Hukou,Nanchang,Shanggao,Taihe,Xingguo and Yujiang county of Jiangxi province,for the purpose of analyzing the utilization status of the regional organic resources,valuing the whole amount and utilization status of organic resources in Jiangxi province,and summarizing the existent problems and bringing forward suggestions.The results showed that from 2007 to 2008 the annual crop straw output of Jiangxi province was about 17646000 t,direct application accounted for 31.8%,indirect application did 12.0%,burning application did 52.5%,other purposes did 3.7%;the annual area of green manure crops was about 533300 hm2,fresh green manure yield was 12372000 t,direct application accounted for 85.6%,indirect application did 14.4%;human,livestock and poultry manure output was about 90740000 t,field application accounted for 64.7%,loss did 35.3%;in Jiangxi province,the nutrients returned by the direct application,indirect application,burning application and other purposes of crop straw accounted for 9.9%,10.1%,22.9% and 4.6% of the field chemical fertilizer nutrients respectively.Base on the above results,we believe that conducting the further research on straw returning technology,extending the area of planting green manure,empoldering new synthetic utilization mode of organic resources,and balancing the district organic resources could enhance the whole soil quality of Jiangxi province.
