新农村视角下农民参与式小型水利

用水户参与式灌溉管理是我国近年来在总结本国管理体制基础上结合国际管理经验提出的一项重大改革。新时期倡导“坚持以人为本，构建和谐社会”的社会主义“新农村”建设与发展过程中，国家高度重视农村基础设施的建设发展特别是农村水利设施，那么农村小型水利工程参与式管理体制目前状况如何、今后如何围绕“新农村”发展将是新时期农村水利管理体制发展所面临和需要解决的。     

新农村建设中创新农业综合开发科技推广工作的几点思考

科技推广作为农业综合开发土地治理项目的一项重要措施,应全面融入于项目区的整体建设之中。必须正确把握国家农业综合开发科技推广的特征与要求,实现思维定势上的创新;国家把解决“三农”问题放在各项战略任务的首位,强调坚持统筹城乡经济社会发展,扎实推进社会主义新农村建设。必须正确理解和准确把握社会主义新农村建设的内涵,实现科技推广工作中技术构建上的创新;同时要正确把握农村现实状况,实现运行机制上的创新。     

发展农业机械化,建设社会主义新农村

现代化的农机装备作为先进的劳动工具,推动了生产力和文明社会的快速发展。建设社会主义新农村,农业机械化既是充要条件,又是必要条件;农业机械化是实现生产发展、生活宽裕、村容整洁、环境和谐的手段、条件、保证。没有农业的机械化,不可能有真正意义上的社会主义新农村建设。     

石墨炉原子吸收光谱法测定新资源食品中的硒含量

建立一种简便、快速、准确的食品中硒的测定方法;检测新资源食品芝麻叶、野生四叶参、野生菜葛根、野生葛花及桑蚕蛹中的硒含量。用1mg·mL-1硝酸镍为基体改进剂,加入体积分数为0.1%TritonX-100和0.5%硝酸(1∶1),以改善样液的表面张力。用HITACHIZ-5000型石墨炉原子吸收光谱仪及全自动进样方法进行硒含量测定。石墨炉采用光控升温方式,硒的灰化温度按程序升温方式进行,程序升温分为干燥、灰化、原子化和净化。该方法的测定限为18.6μg/L,精密度为3.26%￣9.29%(RSD),加标回收率为92.1%￣108.8%。该方法具有测定简便、快速和准确等特点,可作为食品中硒含量测定的良好方法。     

Tissue Culture and Rapid Propagation of Actinidia chinensis

It has been briefly studied and reported that Actinidia chinensis , one of economic woody plants, has been bred with the method of plant tissue culture. Aim at the shortage of traditional plant tissue culture ways which ignored the refinement and transplant of test-tube seedling, it strengthen the study to breeding and management of Actinidia chinensis seedlings before they grow up and become mature seedlings. Through our explore, the transplant survive rate of tissue-culture seedlings attain to about 85%.This study is the improvement to traditional breeding seedling means and it is helpful to the rapid propagation of those economic woody plants.     

Tissue Culture and Rapid Propagation of Echinacea Purpurea

It is a burgeoning application field for the biotechnology that to apply the technique of plant tissue culture breed seedling. The authors study the responses of Echinacea purpurea to different proportion plant growth hormone or auxin through adopting the culture tissue technique on the MS. The integrated seedling of Echinacea purpurea can be cultivated by callus, subculture, differentiation and rhizogenesis. The surviving rate of Echinacea purpurea seedling transplant are improved by appropriate sound stimulation appropriate. Study harvest offers the gist for the large-scale breeding seedling and the officinal resource exploitation of Echinacea purpurea in our country, and avoid some traditional handicap in breeding seedling of Echinacea purpurea, such as the difficult of seed collection, low burgeoning rate, and the disadvantage for large-scale propagation.     

Development of Assembly-Type RC Structure and Building Industrialization

Based on the analysis of the status of building construction in China, the development of Assembled Structure System (ASS) can solve not only the problems in construction, but also is the key for realization of building industrialization. On the basis of technique innovations, a study on the structural performance, construction method and precast production of ASS should be carried out to inherit the old one and overcome its demerits. The process reengineering should be done in the construction enterprise to promote the development of building industrialization.     

加强土地整理,推进新农村建设

建设社会主义新农村是党中央统筹城乡发展的战略决策,是我国现代化进程中的重大历史任务,也是解决"三农"问题的切入点。土地整理是社会经济发展到一定阶段解决土地利用问题的必然选择,是指在农村区域内,通过行政、经济、法律和技术等手段,对田、水、路、林、村等的综合整治,是新农村建设目标的重点,也是促进新农村建设的重要保障手段。在分析土地整理概念及其对社会主义新农村建设重要作用的基础上,提出了推进新农村建设中我国土地整理的着眼点。     

搞好农业综合开发 加快社会主义新农村建设

农业综合开发应以发展农村生产力、建设现代农业和繁荣农村经济为着力点,紧紧抓住建设社会主义新农村的大好机遇,全面落实科学发展观,理清工作思路,创新工作机制,为加快社会主义新农村建设作出应有的贡献。     

新型花生免耕施肥播种机研制

针对国内花生机械播种机普遍存在缠绕壅堵、出苗不均匀等问题,设计一种新型花生免耕施肥播种机。该机设计新型的破茬清茬防缠绕刀具,并采用同位施肥技术,可一次性完成秸秆粉碎、开沟播种、施肥、覆土镇压等作业。田间试验结果表明:该免耕施肥播种机通过性能良好,有效地解决了秸秆对缠绕壅堵问题。播种、施肥深度合格率和变异系数分别为96%、92%和19.5%、15.6%,作业质量符合农艺要求。
