In summer, the weather is changeable, and high-temperature storms often hit agricultural crops. In recent days, heavy rain and hail weather frequently occur. In order to minimize the loss of vegetables, farmers should do the following protective measures:
I. Implementation of Clear Garden
After the heavy rain, the vegetable garden should be immediately defoliated to prevent the spread of disease, and artificial watering should be organized to wash off the sediment adhering to the stems and leaves, increase the oxygen in the soil, and keep the vegetables in normal breathing state. At the same time, the plants are righted to reduce the mutual extrusion phenomenon. Rehabilitate the severely damaged vegetable fields in time, and consider reseeding the vegetable varieties with short growing period, such as spinach and pakchoi.
Second, make up the fertilizer
After the storm hit, the root activity of the vegetables became weak and the water absorption capacity was poor. At this time, the foliar fertilizer should be sprayed, and 1% of the imported urea solution should be sprayed with the potassium dihydrogen phosphate solution to enhance the ability of absorbing fertilizer. Restore vitality. At the same time, the application of 1.5 kg of urea (or 3 kg of ammonium sulfate) and 0.4 kg of potassium chloride can be applied per acre to promote development. Post-disaster vegetables are prone to downy mildew, powdery mildew, or soft rot. Prevention and control should be strengthened. Spray 72.2% of Proplex 600 times or 69% of Kean-Manganese Zinc WP 500-800 times. Prevent diseases from occurring.
Third, cultivator soil
After the heavy rain, the topsoil of the vegetable gardens was slightly dry, and cultivators were implemented in due course to properly cultivate soil to promote the normal development of vegetables.
