In the aftermath of the earthquake disaster, whether large or medium-sized sheds have completely collapsed, partially fallen, or remain standing, immediate action is essential. It is crucial to repair and reinforce the structural framework and film covering of the sheds. Strengthening the pillars of large and medium-sized greenhouses and repairing scaffolding are also necessary, especially for structures with low resistance to pressure. Additional support frames should be added to prevent further collapse. The bottom layer of the greenhouse should be cleaned and repaired, the shed film should be fixed properly, and the film should be tightly pressed to ensure smooth vegetable cultivation in early spring.
Drainage must be prioritized to reduce flooding. Timely clearing of ditches and removing blockages is essential. Fields that have been flooded and contaminated should be dredged as soon as possible to lower water levels and minimize the duration of flooding.
As soon as possible, daylight exposure should be improved by using straw curtains, shade nets, and other coverings to increase light. However, when uncovering these coverings, it should be done gradually rather than all at once. Sudden exposure to intense sunlight can cause severe water loss in crops, leading to rapid wilting. If possible, nursery rooms should use new, non-drip films for better light transmission.
Pest control is also critical. Prolonged rainy weather creates ideal conditions for disease outbreaks. Therefore, local authorities must focus on disease prevention and control after the rain stops or during periods of intermittent good weather. At the same time, pest management should be carried out promptly to avoid further damage to crops.
