1. Drip Irrigation Fertilization
Drip irrigation is one of the most common methods for applying water-soluble fertilizers containing macronutrients, especially suitable for greenhouse agriculture and arid regions. The fertilizer solution is delivered directly to the crop roots through the drip irrigation system, achieving precise fertilization.
Key Operating Points:
Dissolve the fertilizer in a small amount of water first, stir well, and then inject it into the drip irrigation system.
Irrigate with clean water for 10-15 minutes before fertilization to prevent fertilizer from clogging the drippers.
After fertilization, continue dripping clean water for 10-20 minutes to flush out any residual fertilizer from the pipes.
2. Sprinkler Irrigation Fertilization
Sprinkler irrigation is suitable for field crops or orchards, where the fertilizer solution is evenly sprayed onto the field through sprinklers.
Key Operating Points:
Choose fertilizers with good solubility to avoid clogging the sprinklers.
Sprinkling should be done in the morning or evening to avoid fertilizer burn caused by high-temperature evaporation.
If heavy rain follows spraying, re-fertilize.
