The Zizania latifolia straw and ordinary waste mushroom residue of Qingpu were used as material, and 2 treatments of adding microbial inoculants and non-inoculants( control)were set up. The results showed that the compost with microbial inoculums raised the temperature quickly, and the temperature of compost with microbial inoculums was above 8 5C than CK after heating up In the process of composting the water content and ph of the compost showed a downward trend, and the change trend of the 2 treatments was basically the same. The EC value change amplitude of the compost with microbial inoculums was greater than that of control, but the overall change trend was basically the same. The germination rate of inoculums treatment at the early stage of composting was lower than that of the control, and the germination rate of the 2 treatments reached more than 94% after the end of the composting. In general, the ld obviously improve the temperature of Zizania latifolia straw compost, accelerate the decomposition rate of organic matter in Zizania latifolia straws, accelerate straw decomposition process of Zizania Key words: Zizania latifolia straw; Microbial inoculums; Composting 作物秸秆是一种农业废弃物,如果处置不当,可能会成为环境的污染源。堆肥是处理这种废弃物的 有效途径之一,但秸秆主要由木质素、纤维素、半纤维素等组成,传统的堆肥时间较长,不利于养分的保存 和利用。研究表明,合理地接种外源微生物有利于缩短发酵时间,降低有机物料中的难分解物质,从而提 收稿日期:201608408 基金项目:上海市农委推广项目“家庭农场生态农业技术集成示范"[沪农科推字(2015)第22号] 作者简介:徐四新(1966—),男,本科,副研究员,从事养分管理和农业生态环境保护研究工作。E-mal:xsxofsaas@163.com *通信作者,E-mail; caishumei@saas.sh收稿日期:20160808 基金项目:上海市农委推广项目“家庭农场生态农业技术集成示范”[沪农科推字(2015)第 22号] 作者简介:徐四新(1966—),男,本科,副研究员,从事养分管理和农业生态环境保护研究工作。Email:xsxofsaas@163.com 通信作者,Email:caishumei@saas.sh.cn 上海农业学报 2018,34(1):3740 ActaAgriculturaeShanghai DOI:10.15955?j.issn10003924.2018.01.07 文章编号:10003924(2018)0103704 微生物菌剂对茭白秸秆堆肥过程的影响 徐四新,诸海焘,余廷园,蔡树美 (上海市农业科学院生态环境保护研究所,上海 201403) 摘 要:为提高茭白秸秆堆肥的质量,以上海市青浦区的茭白秸秆和普通废菌菇渣为材料,设置加微生物 菌剂和不加菌剂(对照)2个处理,进行了微生物菌剂对茭白秸秆堆肥过程影响的试验。结果表明:接种菌剂的 茭白秸秆堆肥温度上升迅速,升温后堆体的温度比对照高 8.5℃以上;在堆肥过程中,堆体的含水量和 pH均呈 下降趋势,2个处理的变化趋势基本一致;接种菌剂处理堆体的 EC值变化幅度大于对照,但总体变化趋势基本 一致;在堆肥前期,接种菌剂处理的发芽率低于对照,堆肥结束后 2个处理的发芽率均达到 94%以上。总的来 看,接种菌剂可明显提高茭白秸秆堆肥的温度,加快茭白秸秆中有机物质的分解速度,加速茭白秸秆腐熟的进 程,有利于堆肥质量的提高。 关键词:茭白秸秆;微生物菌剂;堆肥 中图分类号:S141.4 文献标识码:A Effectofmicrobialinoculumsoncompostingprocessof Zizanialatifoliastraw XUSixin,ZHUHaitao,YUTingyuan,CAIShumei (InstituteofECOEnvironmentandPlantProtection,ShanghaiAcademyofAgriculturalSciences, Shanghai201403,China) Abstract:InordertoimprovethequalityofZizanialatifoliastraw compost,theeffectofmicrobial inoculumsoncompostingprocessofZizanialatifoliastrawwerestudied.TheZizanialatifoliastrawandordinary wastemushroomresidueofQingpuwereusedasmaterial,and2treatmentsofaddingmicrobialinoculantsand noninoculants(control)weresetup.Theresultsshowedthatthecompostwithmicrobialinoculumsraisedthe temperaturequickly,andthetemperatureofcompostwithmicrobialinoculumswasabove8.5℃ thanCKafter heatingup.Intheprocessofcomposting,thewatercontentandpHofthecompostshowedadownwardtrend,and thechangetrendofthe2treatmentswasbasicallythesame.TheECvaluechangeamplitudeofthecompostwith microbialinoculumswasgreaterthanthatofcontrol,buttheoverallchangetrendwasbasicallythesame.The germinationrateofinoculumstreatmentattheearlystageofcompostingwaslowerthanthatofthecontrol,and thegerminationrateofthe2treatmentsreachedmorethan94% aftertheendofthecomposting.Ingeneral,the microbialinoculumscouldobviouslyimprovethetemperatureofZizanialatifoliastrawcompost,acceleratethe decompositionrateoforganicmatterinZizanialatifoliastraws,acceleratestrawdecompositionprocessofZizania latifolia,andimprovethequalityofcompost.
