1. Agriculture:
   • Fertilizer: As a high-concentration, quick-acting fertilizer suitable for various crops and soils, especially for those preferring ammonium and requiring phosphorus.
   • Soil Amendment: Combined with sodium gluconate in appropriate proportions, it can improve soil buffering capacity and enhance phosphorus fertilizer utilization.
   • Foliar Spray: Its weak acidity favors the survival and proliferation of probiotics, creating a comfortable environment for crop roots.
2. Industry:
   • Fire Retardant: Used in fire retardants for wood, paper, and textiles, as well as additives in fire-resistant coatings.
   • Chemical Nickel and Copper Plating: Applications in metal surface treatment.
   • Water Treatment: As an anode corrosion inhibitor, forming a protective film on metal surfaces.
3. Laboratory:
   • Chemical Reagent: Used to test hydrogen ion concentration in solutions.
4. Others:
   • Food Additive: For bread improvers and food additives.
   • Electronics Industry: Used as an etching agent.
   • Recirculating Water and Boiler Water Treatment: As a bioculture agent.

Detailed Usage Instructions

1. Base Fertilizer: Applied to soil in combination with tillage, or post-seeding by trenching for dryland crops, with an application rate of approximately 10-15 kg per mu, combined with ammonium bicarbonate and urea.
2. Top Dressing: Applied as a foliar spray at a concentration of 0.5%-1.0%.
3. Seed Fertilizer: Used in controlled quantities, typically 3-5 kg per mu, avoiding direct contact with seeds to prevent germination issues and seedling burn.
4. Foliar Spray: Diluted 800-1200 times, with multiple small applications yielding optimal results.
5. Seedling Stage: Irrigated or drip-fed at a 1000-2000-fold dilution, providing efficient phosphorus sources for seedlings.
6. Transplanting Stage: After transplanting, applied at a 1000-2000-fold dilution through irrigation, root feeding, or drip feeding to promote root growth.
