In this study, fermentation-based organic fertilizer (OF) was produced from the aboveground parts of Fallopia japonica (Houtt.) Ronse Decr. The quantity of N in OF (17.2 kg t⁻¹ fresh lactic-fermented OF) was higher than average in cattle farmyard manure, but on a comparable level to solid poultry and rabbit manure. The OF was applied on a field to evaluate its effect on Chinese cabbage. The applied nutrients with OF N159 were 159, 44 and 121 kg ha⁻¹ for N, P, and K, respectively. The applied nutrients with OF N317 were 317, 38, and 200 kg ha⁻¹ for N, P, and K, respectively. The average mass of marketable Chinese cabbage (Brassica pekinensis Rupr.) single heads ranged from 253 g with N0 treatment to 602 g with N317 treatment. The nutrient recovery efficiency RE_N,P,K was 37, 20, and 50% for N317 and 55, 48, and 77% for N159. The OF was found to be a suitable alternative to farmyard manure. Additionally, OF produced from F. japonica could complement existing approaches to limit the spread of invasive species in cities. Further research should focus on perennial crop rotations and cropping patterns, different soil types, and a greater variety of crops and consider the possible retention of urban farmers using fertilizer from invasive plants.

支持城市农业的入侵植物：来自日本虎杖的发酵有机肥

在这项研究中，发酵有机肥 (OF) 是从Fallopia japonica (Houtt.) Ronse Decr的地上部分生产的。OF（17.2 kg t ^-1新鲜乳酸发酵 OF）中的 N 量高于牛农家肥的平均值，但与固体家禽和兔粪的水平相当。将OF应用于大田以评估其对大白菜的影响。对于 N、P 和 K，使用 OF N159 施用的养分分别为 159、44 和 121 kg ha ^-1。对于 N、P 和 K，使用 OF N317 施用的养分分别为 317、38 和 200 kg ha ^-1。市售大白菜（Brassica pekinensis）的平均质量Rupr.) 单头的范围从使用 N0 处理的 253 g 到使用 N317 处理的 602 g。N317的养分回收效率 RE _N、P、K为 37、20 和 50%，N159 为 55、48 和 77%。OF被发现是农家肥的合适替代品。此外，从F. japonica生产的 OF可以补充现有的方法，以限制入侵物种在城市中的传播。进一步的研究应侧重于多年生作物轮作和种植模式、不同的土壤类型和更多种类的作物，并考虑使用入侵植物肥料的城市农民的可能保留。
