Functional nutrient soil for promoting early growth of tobacco plants and preparation method thereof
By combining the fermentation of compound microbial agents in functional nutrient soil with the synergistic effect of functional materials, the problem of weak rhizosphere microecological environment regulation ability of flue-cured tobacco seedling substrate has been solved, achieving the effects of early and rapid growth of tobacco plants and high yield and quality of tobacco leaves.

AI Technical Summary
Existing flue-cured tobacco seedling or transplanting substrates have weak ability to regulate the rhizosphere microecological environment and mismatched nutrient release, which makes it difficult for roots to form in the early stage and easily leads to stunted seedlings. In addition, the lack of synergistic application of functional materials affects the early growth and development of tobacco plants and the quality of tobacco leaves.
Using functional nutrient soil, a micro-ecosystem suitable for root development is constructed through fermentation with compound microbial agents and precise addition of novel functional materials. It provides optimized physical structure, slow release of nutrients, and microbial regulation. The synergistic effect of components such as sandy loam, modified cinder, biochar, and seaweed extract promotes root growth.
It significantly promotes early and rapid growth of tobacco plants, enhances root development and above-ground dry matter weight, shortens the period of seedling formation, and improves tobacco yield and quality, meeting the needs of both large-scale and small-scale production.
