Abstract

Current agriculture faces the challenge of producing food with the least interference from the environment. In this sense, the implementation of ecological agricultural practices is essential to obtaining healthy and more sustainable production systems. The objective of this study was to investigate the impact of different inoculation technologies on formulations of bokashi-type biofertilizer and its application as soil and substrate organic amendment. We examined the effects of treatments on the chemical and biological quality of the evaluated formulations, as well as their influence on the agronomic and nutritional characteristics of red-beet and cabbage crops in the field. The metagenomic analysis of the taxonomic profile of the microbiological populations revealed relative abundance of plant growth-promoting rhizobacterial genera, including Azospirillum sp., Rhizobium sp., Bradyrhizobium sp., Burkholderia sp., Paraburkholderia sp., and Paenibacillus sp. in the evaluated formulations. Additionally, no phytopathogenic contaminants were detected among the investigated treatments. The highest yields of field-grown beet crops were obtained from seedlings produced using the following treatments: bokashi biofertilizer + biodynamic preparations P502-P507, bokashi + Chamomilla 12 CH, and bokashi + Carbo vegetabilis 12 CH. The increase in productivity of cabbage plants was higher in the treatment bokashi + Calcarea carbonica 12 CH.

生物肥料配方的质量及其在生态蔬菜生产中的应用

当前农业面临的挑战是在生产粮食时尽量减少对环境的干扰。从这个意义上说，实施生态农业实践对于获得健康和更可持续的生产系统至关重要。本研究旨在探讨不同接种技术对博卡什型生物肥料配方及其作为土壤和基质有机改良剂应用的影响。我们考察了处理对所评价配方的化学和生物品质的影响，以及它们对田间红甜菜和卷心菜作物农艺和营养特性的影响。微生物种群的宏基因组分析显示，在评价配方中，促进植物生长的根瘤菌属相对丰富，包括氮螺旋菌属、根瘤菌属、慢生根瘤菌属、伯克氏菌属、副伯克氏菌属和芽孢杆菌属。此外，在所调查的处理中未检测到植物致病性污染物。在田间种植的甜菜作物中，施用bokashi生物肥料+生物动力制剂P502-P507、bokashi +洋甘菊12ch和bokashi +碳蔬菜12ch的幼苗产量最高。白菜植株产量的提高在bokashi +碳酸钙12ch处理下更高。

期刊介绍： Horticulturae (ISSN 2311-7524) is an international, multidisciplinary, peer-reviewed, open access journal focusing on all areas and aspects of temperate to tropical horticulture. It publishes original empirical and theoretical research articles, short communications, reviews, and opinion articles. We intend to encourage scientists to publish and communicate their results concerning all branches of horticulture in a timely manner and in an open venue, after being evaluated by the journal editors and randomly selected independent expert reviewers, so that all articles will never be judged in relation to how much they confirm or criticize the opinions of other researchers.
