世界人口正在增加,预计到2050年将达到100亿,粮食安全问题正在成为全球关注的问题。为了维护全球粮食安全,在不断变化的气候条件下提高作物生产力至关重要。传统的农业做法经常使用人工/化学肥料来提高作物生产力,但这些对环境和人们的健康有许多负面影响。为了解决这些问题,研究人员多年来一直专注于替代作物施肥方法,生物肥料作为农业实践的重要组成部分正在全球迅速普及。生物肥料是由本土植物生长促进根际细菌(PGPR)制成的活性制剂,环境友好,和经济的生物肥料,通过直接或间接促进植物发育来积累作物生产力,是植物营养和可持续农学的可再生来源。该综述旨在全面概述有关微生物接种剂作为生物肥料的当前知识,包括他们的类型,行动机制,对作物生产力的影响,挑战,以及与使用微生物接种剂相关的限制。在这次审查中,我们通过进行固氮等多种活动,专注于生物肥料在植物生长发育中的应用,铁载体生产,植物激素生产,营养溶解,并促进作物容易吸收。Further,我们讨论了PGPRs的间接机制,在发展对病虫害的诱导系统抗性方面,作为植物病原体的生物防治剂。这篇综述文章简要概述了微生物接种剂在提高作物生产力方面的思想和用途,并讨论了使用微生物接种剂的挑战和局限性。
The world\'s population is increasing and is anticipated to spread 10 billion by 2050, and the issue of food security is becoming a global concern. To maintain global food security, it is essential to increase crop productivity under changing climatic conditions. Conventional agricultural practices frequently use artificial/chemical fertilizers to enhance crop productivity, but these have numerous negative effects on the environment and people\'s health. To address these issues, researchers have been concentrating on substitute crop fertilization methods for many years, and biofertilizers as a crucial part of agricultural practices are quickly gaining popularity all over the globe.
Biofertilizers are living formulations made of indigenous plant growth-promoting rhizobacteria (PGPR) which are substantial, environment-friendly, and economical biofertilizers for amassing crop productivity by enhancing plant development either directly or indirectly, and are the renewable source of plant nutrients and sustainable agronomy. The
review aims to provide a comprehensive overview of the current knowledge on microbial inoculants as
biofertilizers, including their types, mechanisms of action, effects on crop productivity, challenges, and limitations associated with the use of microbial inoculants. In this
review, we focused on the application of
biofertilizers to agricultural fields in plant growth development by performing several activities like nitrogen fixation, siderophore production, phytohormone production, nutrient solubilization, and facilitating easy uptake by crop plants. Further, we discussed the indirect mechanism of PGPRs, in developing induced system resistance against pest and diseases, and as a biocontrol agent for phytopathogens. This
review article presents a brief outline of the ideas and uses of microbial inoculants in improving crop productivity as well as a discussion of the challenges and limitations to use microbial inoculants.
