未雨绸缪抓好农业标准化   总被引:3,自引:1,他引:2  
当前,我国的农业和农村经济正处于新的发展阶段.一方面,农产品市场需求发生了重大变化,农产品面临市场的严峻考验;另一方面,农业生产结构性矛盾比较突出,农民增产不增收、收入增长趋缓的现象日渐明显,影响和制约了农村经济的持续快速健康发展.尤其是在我国已加入WTO的形势下,加快推进农业标准化生产,使农业生产的产前、产中、产后全过程纳入标准生产和标准管理的轨道,从而获得最佳的经济、社会、生态效益,已是迫在眉睫,刻不容缓.现在,这方面的工作各地刚刚起步、刚刚破题,有大量问题亟待解决.本文就推行农业标准化,谈几点粗浅的看法.  相似文献

The Pittsburgh Conference on Analytical Chemistry and Applied Spectroscopy is the largest meeting devoted to chemical instrumentation in the United States, and probably the largest in the world. From 1 to 5 March, more than 7500 scientists gathered at the Cleveland Convention Center to listen to some 497 papers and to visit the booths of 324 instrument manufacturers and distributors. Another 3000 visited only the instrument exhibition. Because so many manufacturers exhibit their established instruments and introduce new ones at the Pittsburgh Conference (which is so named because it is sponsored by the Society for Analytical Chemists of Pittsburgh and the Spectroscopy Society of Pittsburgh even though it has been held in Cleveland for the past 9 years), it is an ideal place to examine trends in instrumentation and, thereby, current trends in chemistry. Many of those trends are discussed in the following stories. Other trends include the growing number of women participants. As recently as 5 years ago, there was only one woman among the manufacturer's representatives at the meeting. No figures are available this year, but women probably accounted for at least 5 percent of the sales force. Also the number of professional women visiting the exhibition was much greater than ever before. Another important trend was the enthusiasm of the visitors to the exhibition. Many of them seemed to have money in their pockets and to be ready to spend it, an indication that the instrument business-and, therefore, the physical sciences-will enjoy a year of healthy growth.  相似文献
