Soilless cultivation enhances agricultural efficiency and yield by precisely managing plant root environments. Future innovations in sustainable substrates and microbiome engineering are key for low-carbon, precise agriculture.
Area of Science:
- Agricultural Science
- Environmental Science
- Microbiology
Background:
- Soilless cultivation offers a sustainable alternative to traditional agriculture by precisely controlling the crop rhizospheric environment.
- It addresses limitations in traditional farming related to resources and environmental impact.
Purpose of the Study:
- To systematically review soilless cultivation technologies, nutrient management, rhizosphere microorganism interactions, and future directions.
- To highlight the technical advantages and innovation potential of soilless farming.
Main Methods:
- Comprehensive literature review of soilless cultivation systems.
- Analysis of nutrient solution dynamics and intelligent management strategies.
- Examination of rhizosphere microbial interactions and their impact on crop health.
Main Results:
- Solid and non-solid substrate cultivation boosts resource efficiency and yield, but substrate sustainability and cost require attention.
- Dynamic nutrient solution regulation and intelligent systems improve nutrient uptake.
- Rhizosphere microbes enhance crop health via nitrogen fixation, phosphorus solubilization, and pathogen antagonism, though organic systems may face microbial imbalance.
Conclusions:
- Future research should prioritize eco-friendly substrates, intelligent control systems, and microbiome engineering for soilless cultivation.
- Development is directed towards low-carbon, precise, and spatial applications to support food security and resource recycling.
