Rescue measures after flooding rice fields
In recent days, heavy rains in the south have been affected by continuous heavy rains and many floods have been hit. The heavy rainfall process has seriously affected agricultural production. The following rescue measures are proposed for the affected early rice and ratoon rice:
As soon as possible, the flooded fields should be drained. It is necessary to eliminate the accumulated water in the field as soon as possible. It is necessary to seize time and speed, clean up the ditches and drains in time, and reduce the damage of waterlogging. When the water is flooded for about 24 hours, the water should be washed immediately after the water is retreated, and the mud on the leaves should be washed to restore the normal photosynthetic function of the leaves and promote the growth of the plants. For different types of fields, targeted measures should be taken depending on the specific situation. It should be noted that after the rain, it will encounter high temperature and hot weather. Therefore, it is not possible to drain the field water at one time and maintain a thin water layer to prevent the high-intensity leaf surface evaporation from causing the plant to lose water and die.
Timely fertilization of rice should be timely fertilized after flooding to promote the recovery of rice after the disaster. The fertilizer type is mainly available nitrogen fertilizer, and combined with phosphorus and potassium fertilizer. To distinguish between seedlings, classify remedies. For fields with short flooding time and light damage to rice seedlings, the amount of fertilizer applied may be less; for those with long flooding time and heavy damage to rice seedlings, it is necessary to apply more points, but multiple light application methods must be adopted to prevent one-time fertilization. Too much, causing damage to the seedlings. At the same time as the fertilizer is applied, the combination of “slipping and chasing†is applied to spray high-efficiency foliar fertilizer to promote the recovery of rice.
After strengthening the water management drainage, on the basis of the floating mud on the paddy field, adhere to dry and wet, intermittent irrigation of fresh water, not only to maintain soil ventilation, but also to meet the needs of rice seedlings.
Pay attention to the prevention and control of pests and diseases. The leaves and cockroaches of the flooded rice are more tender and green, and are susceptible to rice planthoppers, rice leaf roller, rice stem borer, rice blast, and sheath blight. The affected rice should be carefully prepared for the prevention and control of rice planthoppers and rice leaf roller. Tricyclic azole or rice blast is used to control rice blast; imidacloprid and chlorpyrifos are used to control rice planthopper; chlorpyrifos and other pesticides are used to control aphids and rice leaf roller.
