为解决劳动力锐减、综合效益低下以及经营主体的改变带来的问题,保障粮食安全,提高复种指数,发展再生稻等高效种植模式是稳定粮食生产的重要途径.通过温光气象历史数据分析、熟期适中再生性强的优质品种筛选试验和基于机械化栽培条件下再生季留桩高度、肥料运筹方式探索等,在关键技术突破后系统总结优化,构建沿江地区稻-稻周年种植制度下再生稻丰产增效技术并成功示范,进而开展大面积推广应用.
通过2018年一年的努力,安徽省农业机械试验鉴定站(下称“安徽站”)致力于强弱项、补短板、破瓶颈,重点抓好既有鉴定能力重新认定和扩项认定,着力推进部省两级推广鉴定能力建设.同时,围绕中心、履职尽责、服务大局,规范开展农机试验鉴定和质量监督工作,扎实推进农机化标准化和信息化步伐,农机化技术支撑作用显著加强,稳中有迸、稳中向好、稳中提质.
近年来,安徽省农机行业职业技能鉴定工作持续稳定发展,为推进农机化工作的开展和助力乡村振兴,提供了坚实的人才保障和有力的技术支撑. 一、基本情况 安徽省农机行业职业技能鉴定站(农业64号站)于2002年11月由劳动部批准成立并设在原安徽省农机管理局,2010年10月,该机构和职能移交到安徽省农业机械试验鉴定站.目前,安徽省共建立了51个农机行业职业技能鉴定工作分站,其中,13个市级分站,37个县(区)工作站.2012年、2014年分别有10个单位被评为全国农机行业职业技能培训和鉴定示范基地.
TZ4-2011《农业机械推广鉴定通则生产条件审查》2.5.5条规定:“企业应根据产品特点建立适宜的整机出厂检验制度,并有效执行.应保存检验记录.”此条款为关键条款,即不满足此条款要求,则生产条件审查不通过.此条款关键点在于正确识别企业是否在保证整机出厂质量的前提下“根据产品特点”并“建立适宜的”整机“出厂检验制度”,而且按照制度“有效执行”.没有建立整机出厂检验制度或制度不适宜或没有有效执行都是不符合本条款的要求.
雾霾,现已严重影响人们身体健康、干扰人们生活.面对雾霾,政府积极应对,对影响雾霾的各个因素抓整治;人们时刻关心、关注雾霾的变化,提出相应的对策.然而雾霾依然存在,挥之不去,并且有加重之势.如何治理雾霾,成为人们经常谈论的话题.
Farm mechanization is the basis and important component of agricultural modernization,it occupies an important position in promoting agricultural modernization.The development status and problems of anhui agricultural mechanization were analyzed;and the relationship between the development of agricultural mechanization and the net income of farmers and agricultural output value was objectively analyzed from technical economic aspects of Anhui agricultural mechanization;according to these,some countermeasures to accelerate the development of agricultural mechanization in Anhui province.
Fungus Pleurotus florida and chemical sodium hydroxide(NaOH), ammonia(NH3), and urea(CO(NH2)2 were used for biological and chemical pretreatment of corn stalk, respectively. It was found that the main chemical compositions such as lignin, cellulose, and hemicellulose were degraded greatly, and the physical structure of lignocellulose matrix changed as well through both pretreatments, which contributed to the improvement of anaerobic digestion efficiency of corn stalk. The anaerobic digestion experiments showed that all biological and chemical pretreatments, except urea treatment, helped increase biogas production, whereas NaOH was found to be the best one and capable of increasing biogas production by 78.3% and 13.2% as compared to the untreated and biologically treated one, respectively. Chemical pretreatment has some advantages over biological one such as easy operation, shorter treatment time, and higher biogas production. Pretreatment with NaOH (addition of 8% of corn stalk dry matter) is recommended for large scale biogasification of corn stalk. Proper chemical pretreatment could improve biogasification efficiency of corn stalk as well as other crop stalks.

[编者按]农业机械推广许可证制度从1983年实施以来,对我国农业机械化事业的健康发展起到积极的保障和促进作用.随着农机鉴定工作逐步与国际接轨,以ISO9000系列标准为基础的农机产品质量认证已经展开,在目前我国农机工业企业管理、技术水平参差不齐的情况下,如何更好地开展农机推广许可证工作和农机产品质量认证工作,是时代给我们提出的新课题.
GB/T8097-1996<收获机械联合收割机试验方法>(以下简称"GB/T8097-1996")1997年7月1日开始实施.它代替GB/T8097-87<谷物收获机械试验方法>.尽管该标准在技术要素上与ISO8210:1989<收获机械联合收割机试验方法>等效,在一般要素和补充要素方面根据国内情况有些改变,但在实际使用中,尚存在一些问题.
