Heavy rainfalls can severely impact vegetable growth. To reduce losses caused by adverse weather conditions, restore production, and ensure supply, certain measures must be taken. Below are key points for managing vegetables after heavy rainfalls:
Greenhouse Vegetable Management Strategies
-
Facility Maintenance: Greenhouses with good drainage, higher elevation, and intact structures are less affected. Post-rain sunshine management is crucial.
-
Drainage: Clear drainage ditches and channels promptly in flooded greenhouses to minimize vegetable submersion time and repair damaged structures.
-
Harvesting: Prioritize harvesting marketable vegetables to increase revenue and alleviate plant stress.
Open-Field Vegetable Management Strategies
-
Water Drainage: After flooding, promote root growth by lowering groundwater levels and opening furrows. Support fallen plants, loosen soil, and apply soil amendments to facilitate recovery.
-
Nutrient Supplementation: Apply phosphorus, nitrogen, and potassium fertilizers to replenish lost nutrients and use foliar fertilizers and microbial fertilizers to enhance plant health.
-
Disease and Pest Control: Monitor and treat diseases and pests promptly, as vegetables become more susceptible after heavy rains. Choose effective fungicides and insecticides and adjust planting schedules accordingly.
-
Timely Replanting: For severely affected or flooded areas, replant or sow new crops promptly. Clear fields, disinfect, and replant fast-growing leafy vegetables to maximize economic returns.
Implementing these strategies is essential to enhance vegetable productivity, improve production management, and ensure disaster preparedness and recovery, ultimately securing stable supply and increased income.
