课程名称：生物水培农业 课程概述： 生物水培农业强调有机种植，在不同国家其含义各异。对许多消费者而言，有机意味着不使用不必要的化学物质或农药。与传统水培方法相比，生物水培需要更高的关注度，尤其是在视觉上对植物的观察和检查，尽管PH和电导率（EC）参数依旧重要。生物水培依赖于微生物与植物之间的共生关系，在无土的自由水环境中，益生菌的生存和活跃受到环境变化的影响。 生物水培被认为是无土农业的下一次革命，能够利用营养丰富的水源生产作物，且不依靠化学肥料。生物水培不仅回收蔬菜和其他作物所需的养分，还依赖于微生物在营养回收过程中的关键作用，例如通过有机废物降解来维持水质良好，以及养分的矿化和转化以供植物吸收。生物水培系统中的液体肥料通常以蚯蚓腐殖土或鸟粪为主要成分，经过低温浸泡在罐中并与固体和有机废物过滤系统连接进行有机灌溉。
" Organic" gardening or farming means different things in many countries. To many consumers it means food grown without unnecessary chemicals or pesticide. Managing bioponics needs much more attention than traditional hydroponic growing methods. Not in terms of time spent, but in terms of visual attention and examination. Bioponics is managed by eye as much as with PH and EC parameters, although these do still remain important. Bioponics works through a symbiotic relationship between you microorganisms and your plants. In free water, without the buffering capacity of soil. life is hard to impossible for beneficials and even when established on roots and substrate their activity and health can be affected by rapid changes in environment.Bioponics is the next revolution of soilless agriculture in which crops can be produced from nutrient-rich streams, without the use of chemical fertilizers. Bioponics both recovers nutrients for vegetables and other crop from nutrient rich products. Microorganisms in bioponics play significant roles in nutrients recovery such as organic waste degradation to maintain good water quality as nutrient mineralization and transformation for plant uptake. The liquid fertilizer employed in bioponics systems is generally produced from either worm humus or bird manure after having been infused at a low temperature inside tanks for organic fertigation connected to systems for filtering solid and organic waste.
