Fertigation: Sprayer Manual Fertilizer Fertilizer
2020-10-10 17:14:35
The sprayer fertilizer method uses a manual pedal pesticide sprayer (working pressure 0.8-1.0Mpa) to inject the dissolved fertilizer into the irrigation pipe system. Manually aspirate every minute, 20-30 times, and the amount of liquid absorbed is 3.3-3.7L. For fertilizer injection, connect the outlet of the atomizer to the small valve of the branch pipe. The pipette is put into the barrel of the fertilizer solution. The head of the pipette is wrapped with a nylon filter (80-120 mesh). Fertigation time should not be too short, usually 15-20 minutes per acre fertilizer. The method is fast in injection, simple in method, and convenient in operation, and is suitable for plots or greenhouses where fertilization area is small. The disadvantage is that the concentration of infusion fluid is sometimes inconsistent. When the area is large, more labor is required.
