高效多功能复合肥在马铃薯生产中的应用效果研究

近年来，植物生长调节剂及各种叶面肥料在马铃薯生产中的应用日益增多，且已取得了初步的效益。为此，我们对青海黎化实业有限责任公司生产的高效多功能复合肥在马铃薯上进行叶面喷施试验，测定其对马铃薯产量的影响以及最佳施用量，为今后大面积应用提供科学依据。１材料与方法高效多功能复合肥由青海黎化实业有限责任公司生产，复合磷酸二氢钾由安徽岳西安大化工公司生产，供试马铃薯品种为青薯２号。本试验中高效多功能复合肥，设４个处理，每６６７m２施用量分别为１００g、１５０g、２００g、２５０g，复合磷酸二氢钾１５０g／６６７m…     

Analysis of Application of Information in Mid - mini Enterprises on Condition of Mass- economy

The group of Mid - mini enterprises under mass - economy is the intermediate organization built up by specialized division of work and cooperation. This kind of organization is flexible in operation with high efficiency, but difficult in development of new technology. On the basis of analyzing the character and deficiency of the mid - mini enterprises, in this paper, through providing a framework of information service platform for the mid - mini enterprises to enhance their creative ability and complex competition. The construction and operational strategy of such platform are investigated. Finally a successful case study is given.

Al2O3含量对烧结初始液流动行为的影响

在铁矿粉烧结过程中,初始液相流动行为是烧结矿固结效果的重要影响因素。采用微型烧结法,探讨了Al2O3含量对初始液相流动行为的影响,并通过对初始液相微观结构的解析,揭示了Al2O3含量对初始液相气孔分布和结构的影响规律。实验结果表明,初始液相的流动性指数随着Al2O3含量提高而降低。水淬试样的XRD实验结果结果证实,Al2O3含量的增加提高了复合铁酸钙的稳定性,降低了初始液相的流动能力。此外,初始液相流动性亦会对气孔性质产生影响。高Al2O3初始液相中气孔结构不规则程度提高,且小于50 μm气孔数目也随之增多。
