Study on Risk Management of Investment on Food and Drug Safety of Fiddlehead
Fiddlehead has been used in traditional Chinese medicine since Han Dynasty. However fiddlehead are still underutilized and hence wasted. In order to better utilize fiddlehead resources, the drug safety of benzene/alcohol extractives from fiddlehead were analyzed by GC/MS. Relative content of each component was determined by area normalization. The main ingredients of benzene/alcohol extractives of fiddlehead were toluene,2-furancarboxaldehyde, 5-(hydroxym ethyl)-, n1-(4-hydroxybutyl)-n3-methylguani dine acetate, 1,3-dihydroxyacetone dimer, sulfurous acid, cyclohexylmethyl hexadecyl ester, 1,4,7,10,13,16-hexaoxanonadecane, 18-propyl-, 1,6-anhydro-.beta.-d-glucopyranose(levoglucosan), oxirane, hexadecyl-, etc. The results obtained fully indicated that the benzene/alcohol extractives of fiddlehead had the great potential of noble natural biomedicines.
Study on Appropriate Growth Conditions and Cropping Patterns of Pteridium aquilinum
采用塑料大棚、小拱棚、露地栽培3种种植模式,研究了不同种植模式对蕨菜生长环境条件、生长发育和产量的影响.结果表明:蕨菜适宜的出芽气温和地温分别为13～14℃和11～12℃;适宜的出茎气温和地温分别为15～16℃和12～14℃;适宜的孢子形成气温和地温分别为26～27℃和20～22℃.塑料大棚促进蕨菜提前出芽、出茎,采收期较其他模式提前25～39 d,产量达20 800 kg/hm2,分别比小拱棚和露地增产25%和40%.
Analysis: The Agenda 2007 Proposals: Evolution or Revolution?
On 10 February 2004 the Commission published its proposal for the financial perspective 2007-2013. A week later it adopted the third report on economic and social cohesion. These two documents form the basis of the so-called ‘Agenda 2007 reforms’. They will be the greatest challenge for the enlarged EU after the intergovernmental conference, since they will determine the financial basis for EU policy-making until the middle of the next decade. The Agenda 2007 proposals certainly hint at courageous reforms, because they place a previously unheard-of emphasis on performance and quality. Under the proposals, structural operations should generate value for money, and the funds should focus on projects which generate added value at a European level. Overall the Commission’s proposals point in the right direction, because they balance, on the one hand, solidarity for the new Member States and weak regions in the old Member States with, on the other hand, investments in future tasks. Moreover, they constitute a paradigm shift. For the first time, the Common Agricultural Policy will not be the dominant expenditure category. Now it is up to the Member States to examine the proposals politically and find a compromise between sometimes very divergent interests. It is to be hoped that, during the debate over expenditure limits and division of funds, national interests do not outweigh European interests.
