AI Technical Summary

Technical Problem

Mangrove seedling cultivation suffers from problems such as weak salt tolerance, slow rooting, and poor root fixation, leading to salt damage causing wilting, lodging, and low survival rates after planting. Existing seedling substrates are also insufficient in terms of stress resistance and structural enhancement.

Method used

The formula uses a mixture of coconut coir, perlite, and sea sand, with the addition of biochar chitosan quaternary ammonium salt microspheres and modified sepiolite to form porous microspheres and water-resistant composite particles. Combined with compound microbial agents and slow-release calcium, magnesium, and silicon fertilizers, it achieves a synergistic improvement in salt tolerance, root promotion, lodging resistance, and adaptability for planting in tidal flats.

Benefits of technology

It significantly improves the root development, stem robustness, salt stress tolerance, and survival rate of seedlings planted in tidal flats, meeting the needs of mangrove industrial seedling production and efficient planting. It reduces salt ion concentration through biochar chitosan quaternary ammonium salt microspheres and improves matrix structural strength and element release through modified sepiolite, promoting healthy root development.
