会社のニュース The Effect of Potassium Fulvate on Rice

Potassium fulvate's core value for rice lies in promoting root development and seedling vigor, improving quality and yield, enhancing stress resistance, improving soil, and increasing fertilizer efficiency. It offers clear benefits at different growth stages.

I. Seedling Stage Development and Root Strengthening

• Seed Treatment: Increases germination rate and seedling establishment rate (+27%~38%), advancing emergence by 1~3 days.

• Root Promotion: Significantly increases root length, root number (+30%), and root hair density; improves seedling stem base width and fresh/dry weight; enhances resistance to planting damage and promotes rapid greening.

• Cold Resistance: Dark-colored colloids absorb heat, and microbial decomposition releases heat, slightly raising seedbed soil temperature and reducing the risk of late spring frosts and low-temperature seedling rot.

II. Growth Stage Quality and Yield Improvement

•Nutrient Enhancement: Chelates nitrogen/phosphorus/potassium, reduces nitrogen volatilization, activates insoluble phosphorus/potassium in the soil, and significantly increases nitrogen/potassium accumulation in rice (+28%~48%).

• Physiological Regulation: Increases chlorophyll content and photosynthetic efficiency, promoting tillering and floret differentiation; foliar spraying (200mg/L) at the jointing/heading stage can increase yield by up to 24.5% and head rice rate by 8.37%.

• Prevention of Premature Aging: Enhances root vitality and lodging resistance in later stages, resulting in fuller grains, higher thousand-grain weight, and lower empty grain rate.

III. Enhanced Stress Resistance (Saline-Alkali/Drought/Disease)

• Salt Stress: Increases the activity of antioxidant enzymes such as POD/APX, reduces MDA and electrolyte leakage, maintains K⁺/Na⁺ balance, and mitigates salt damage.

• Drought/Disease Resistance: Enhances water retention capacity, improves plant health, and reduces the risk of infection by diseases such as sheath blight and rice blast.

IV. Soil Improvement (Long-Term Application)

• Improves soil compaction, increases aeration and water and fertilizer retention capacity, and alleviates continuous cropping obstacles.

• Promotes the reproduction of beneficial bacteria, optimizes the rhizosphere microecology, and reduces the occurrence of soil-borne diseases.
