Soilless production systems (i.e hydroponics, aeroponics, aquaponics) have become commonplace in urban settings and controlled environments. They are efficient nutrient recyclers, space savers, and water conservers. However, they lack high levels of biological richness in the root microbiome when compared to soil production systems, which may affect plant health and nutrient uptake. To address this issue and incorporate more sustainable practices, beneficial microorganisms (i.e. spp., sp.) can be added in the form of biofertilizers. However, many factors affect impacts of microorganisms and their interactions with plants. In this experiment, Black Summer Pac Choi ( var. Chinensis) was grown for two trials in a Deep-Water system (DWS) or a Nutrient Film Technique system (NFT) with commercial biofertilizers containing spp., , a combination of both, and a control. Plant physiology, nutrient composition, and nutrient uptake efficiency (NUE) were generally negatively affected by spp. both growing systems, indicating that may not be recommended for hydroponic production. However, showed promise as an effective biofertilizer in the NFT systems and had a positive influence on NUE in DWS.
无土栽培系统（即水培、气培、鱼菜共生）在城市环境和可控环境中已变得很常见。它们是高效的养分循环利用者、节省空间者和节水者。然而，与土壤栽培系统相比，它们的根际微生物群落缺乏高度的生物丰富度，这可能会影响植物健康和养分吸收。为了解决这个问题并纳入更可持续的做法，可以以生物肥料的形式添加有益微生物（即 spp.， sp.）。然而，许多因素会影响微生物的影响及其与植物的相互作用。在本实验中，黑夏小白菜（ var. Chinensis）在深水系统（DWS）或营养液膜技术系统（NFT）中进行了两次试验，使用了含有 spp.、 、两者组合的商业生物肥料以及一个对照。在这两种栽培系统中， spp. 通常对植物生理、养分组成和养分吸收效率（NUE）产生负面影响，这表明 可能不推荐用于水培生产。然而， 在NFT系统中显示出作为有效生物肥料的潜力，并且对DWS中的NUE有积极影响。
