Carbon-Silicon
Characteristics
- Carbon Tube Structure: Nano carbon components form a carbon nanotube network with a high surface area and strong adsorption capacity.
- Silicon Enrichment: Silicon is adsorbed onto the carbon nanotubes, making it easily absorbable by plants.
- High Stability: The carbon–silicon composite is stable, preventing rapid leaching and ensuring sustained nutrient release.
Effects
- Enhanced Plant Structure: Silicon strengthens the cell walls, making plants more robust and resistant to physical stress.
- Improved Disease Resistance: Silicon enhances plant resistance to diseases and pests by forming physical barriers and stimulating natural defense mechanisms.
- Stress Tolerance: Plants using nano carbon–silicon fertilizer exhibit stronger tolerance to abiotic stresses such as drought, salinity, and extreme temperatures.
Advantages
- Sustained Nutrient Release: The nano carbon structure ensures the slow and steady release of silicon, providing long-term nutrient availability.
- Enhanced Photosynthesis: Silicon helps optimize photosynthesis, improving overall plant growth and yield.
- Environmental Benefits: Slow-release properties reduce nutrient runoff, minimizing environmental pollution.
- Improved Potassium Uptake: Experiments have shown that nano carbon–silicon fertilizers increase the availability and absorption of potassium, enhancing plant resilience and productivity.
- Field Results: Using 8 g/L of nano silicon dioxide (nSiO2) in the nano carbon–silicon composite fertilizer improves tomato seed germination rate, germination index, and seedling growth.
- Significant Growth Boost: The use of nano diatomaceous earth and nano silicon dioxide increased the dry mass and fresh mass of amaranth by 43.4% and 14.9%, respectively.
- Enhanced Nutrient Absorption: The total absorption of nitrogen, phosphorus, and potassium improved by 36% and 20%, especially boosting potassium availability in the soil.
- Spraying Effect: Spraying nano silicon preparations significantly increases the content of available nitrogen, phosphorus, and potassium in the soil, improving overall soil fertility.
