Once the vegetables are flooded, they have a great impact on the yield. To reduce disaster losses, the following technical measures can be taken.
Draining and removing stains in a timely manner: Prevent the death of plants due to water accumulation and waterlogging, and stop the garden early.
Timely cultivating: When the land can be ploughed, timely cultivating loose soil, remove the compaction, improve soil permeability, and promote root development.
Timely top-dressing: Topdressing with quick-acting nitrogen fertilizer and decomposed organic fertilizer solution is good, and attention should be paid to proper application; 0.3% to 0.5% urea solution, 2% superphosphate calcium leaching solution, 0.2% to 0.3% potassium dihydrogen phosphate solution can also be used. Penshibao, amino acid and other foliar fertilizers are used as foliar sprays to promote normal plant growth and development as soon as possible.
Timely prevention of pests and diseases: After the disaster, the field temperature is high, humidity is high, and it is suitable for a variety of pests and diseases. Pest control should be based on comprehensive prevention and control. Attention should be paid to the use of high-efficiency, low-toxicity, low-residue pesticides. The use of highly toxic and high-residue pesticides is strictly prohibited, and attention should be paid to spraying before and after the evening. Both sides of the blade must be sprayed on both sides.
