家庭厨余垃圾所产浆状有机质的分析研究

在源头对家庭厨余垃圾以“一户一桶一系统”方式进行收集和处理,经过一定时间发酵后成为浆状有机质。对家庭厨余垃圾所产浆状有机质进行性能指标检测,结果表明,其有机质含量高、含水率高、重金属含量低,种子发芽指数达到75%以上,适合作为土壤调理剂使用,在农用地分布式量化施用后,可持续长效增强土壤肥力及活力,具有明显的促进植作物茎叶生长的作用。本研究可为家庭厨余垃圾的有效处理与利用提供一定的数据支撑与参考。

Determination of Physiological Biochemical Parameters and Reproductive Performance in Transgenic sFat-1 Gene Pigs

[Objective] The aim was to evaluate the health of transgenic sFat-1 gene pigs in order to provide a reference for the breeding selection of pig excellent individuals. [Method] 15 physiological biochemical parameters and reproductive performances of 21 negative control pigs and 20 transgenic sFat-1 gene pigs were determined. [Result] The liver functions of some transgenic sFat-1 gene pigs were hurted lightly,and the reproductive performance also decreased lightly. [Conclusion] The determination of physiological biochemical parameters and reproductive performance in transgenic pigs could be taken as one of effective methods in environmental safety evaluation of transgenic pigs.
