Abstract

Vermicompost (VC) products have grown in popularity in plant nutrition and are widely used to improve plant growth and suppress plant diseases. In addition, the choice of chemical-free food and increased public concern for human health and the environment due to the impacts of hazardous inorganic fertilizers have motivated farmers to seek safer and more eco-friendly alternatives. The present study aimed to evaluate the plant-growth-promoting and biocontrol potential of macrophyte biomass-based VC products in tomato plants. The results indicated that tomato plants treated with VC + vermicompost tea (VCT) resulted in 30.74% higher plant height, 20.70% more leaves, 29.05% more fruits, and 61.26% higher total yield than the control plants. In addition, VC products significantly reduced disease incidence by 35–60%, whereas the untreated control had the highest wilt incidence (75%). The study concludes that VC products produced from free-floating aquatic weed biomass (Azolla, Lemna, and Salvinia) could be used as a potential alternative to inorganic fungicides to manage Fusarium wilt disease and as bioinoculants to improve the growth and yield of tomato plants for sustainable crop production.

基于大型生物质的蛭石堆肥和蛭石茶对植物生长、产量和番茄镰刀菌枯萎病生物防治的影响

蛭石堆肥（VC）产品在植物营养方面越来越受欢迎，被广泛用于改善植物生长和抑制植物病害。此外，人们对无化学物质食品的选择，以及公众对有害无机肥料对人类健康和环境影响的日益关注，促使农民寻求更安全、更环保的替代品。本研究旨在评估基于巨藻生物质的 VC 产品对番茄植株生长的促进作用和生物防治潜力。结果表明，与对照植物相比，使用 VC + 蛭石堆肥茶（VCT）处理的番茄植株株高增加了 30.74%，叶片增加了 20.70%，果实增加了 29.05%，总产量增加了 61.26%。此外，VC 产品大大降低了 35-60% 的病害发生率，而未经处理的对照组枯萎病发生率最高（75%）。该研究得出结论，从自由漂浮的水生杂草生物量（Azolla、Lemna 和 Salvinia）中生产出的 VC 产品可作为无机杀菌剂的潜在替代品来管理镰刀菌枯萎病，也可作为生物接种剂来改善番茄植株的生长和产量，从而实现作物的可持续生产。
