Recycled concrete is one of new type concrete that mixed with recycled aggregate at a certain proportion after cleaning , crushing , grading wasted concrete . it is helpful in dealing with rejectamenta of concrete and a bad influence on environment because of castoff 再生混凝土是将废弃混凝土经过清洗、破碎、分级和按一定比例相互配合后得到的“再生骨料”作为部分或全部骨料配制的混凝土。

Then , main projects and synthetic techniques of ecological agriculture construction are discussed . the results indicate that main projects include fertile soil project , water conservancy , forestation and virescence project , agricultural structure adjustment project , agriculture industrialization project , integrated use of agriculture rejectamenta project , high quality and innoxious farm produce project , livestock breeding project , sight - seeing agriculture project , etc . the suited techniques include ecology location scheme technique , agriculture rejectamenta use technique , energy source regeneration technique , sewage biologic depuration technique , innoxious farm produce technique , soil fertility increase technique , ecological control technique of plant disease and insect pests , economizing water technique of dry farming , agriculture environment reconstruction technique , etc . lastly the study brings forward the countermeasure and advice of ecological agriculture development 根据我国生态农业建设成功经验和济南市目前生态农业建设基础,提出济南市生态农业建设重点工程为沃土工程、农田水利工程、造林绿化工程、农业结构调整工程、农业产业化工程、农业废弃物综合利用工程、优质和无公害农产品工程、养殖工程、观光农业工程等;生态农业建设的关键技术为生态位配置技术、农业废弃物资源化绿色技术、能源再生技术、污水生物净化利用技术、无公害农产品技术、地力持续培肥利用技术、农作物病虫草害生态控制技术、旱作农业高效节水技术及农业生态环境综合整治技术等。

These methods include transportation management , storage management , the logistics package and workstation implement , the deposition of rejectamenta and the elaborate manufacturing logistics in dcac , etc . in the aspect of internal logistics management , dcac arranges pretty well and has very high productivity 该公司在建厂的初期就引进了雪铁龙公司先进的物流管理方法，包括运输管理、仓储管理、物流包装和工位安排、废弃物的处理，准时化生产等。在企业内部物流管理上，安排合理，生产效率较高，处于国内领先水平。
