无土栽培系统为传统栽培系统提供了一种环境友好和资源高效的替代方案，适合循环经济计划。本研究的目的是探讨可持续整合的循环肥料在水培-创造一个养分循环的概念，园艺栽培。采用营养膜技术，以11株番茄（Solanum lycopersicum L.）CV. Pannovy）每个重复（n = 4）和处理：两种铵/硝酸盐比例（NH 4+：NO3−）不同的硝化尿基肥料，即（1）“Aurin”（AUR）和（2）“Crop”（CRO）;以及（3）鸟粪石和酒糟的有机-矿物混合物（S+V）;和（4）对照（NPK）。封闭室法适用于气体通量（N2 O，CH 4，和CO2）从根区。再生肥处理的地上部总生物量、鲜重和氮、磷、钾吸收量与对照无显著差异。NPK、CRO和S+V处理的商品果产量相当，而AUR处理的产量较低。较高的NH 4+：NO3−的AUR与增加的开花端腐病的易感性，可能是由于减少的吸收和转运的Ca。最高的糖浓度被发现在S+V，这可能是受酒糟中的有机酸的存在。N2 O排放量在S+V中最高，这符合我们的假设，即N2 O排放量与肥料改良剂的有机碳输入呈正相关。其余处理显示几乎检测不到温室气体排放。具有低NH 4+：NO3-的硝化尿（例如，CRO）在番茄栽培的NFT系统中具有很高的作为循环肥料的潜力，并且S+V被证明提供足够的P和K用于适当的生长和产量。替代性种植策略可补充AUR的组成。本文的在线版本（10.1007/s11356-020-10461-4）包含补充材料，可供授权用户使用。
Soilless culture systems offer an environmentally friendly and resource-efficient alternative to traditional cultivation systems fitting within the scheme of a circular economy. The objective of this research was to examine the sustainable integration of recycling fertilizers in hydroponic cultivation—creating a nutrient cycling concept for horticultural cultivation. Using the nutrient film technique (NFT), three recycling-based fertilizer variants were tested against standard synthetic mineral fertilization as the control, with 11 tomato plants (Solanum lycopersicum L. cv. Pannovy) per replicate (n = 4) and treatment: two nitrified urine-based fertilizers differing in ammonium/nitrate ratio (NH4+:NO3−), namely (1) “Aurin” (AUR) and (2) “Crop” (CRO); as well as (3) an organo-mineral mixture of struvite and vinasse (S+V); and (4) a control (NPK). The closed chamber method was adapted for gas fluxes (N2O, CH4, and CO2) from the root zone. There was no indication in differences of the total shoot biomass fresh matter and uptake of N, P and K between recycling fertilizers and the control. Marketable fruit yield was comparable between NPK, CRO and S+V, whereas lower yields occurred in AUR. The higher NH4+:NO3− of AUR was associated with an increased susceptibility of blossom-end-rot, likely due to reduced uptake and translocation of Ca. Highest sugar concentration was found in S+V, which may have been influenced by the presence of organic acids in vinasse. N2O emissions were highest in S+V, which corresponded to our hypothesis that N2O emissions positively correlate with organic-C input by the fertilizer amendments. Remaining treatments showed barely detectable GHG emissions. A nitrified urine with a low NH4+:NO3– (e.g., CRO) has a high potential as recycling fertilizer in NFT systems for tomato cultivation, and S+V proved to supply sufficient P and K for adequate growth and yield. Alternative cultivation strategies may complement the composition of AUR.
