Early rice wax maturity
Clean in time. When the flood gradually subsides, it is necessary to take time to clean the blades, preferably using a sprayer. Spray the water to remove the sand stained on the leaves, focus on cleaning the top, ie the ear and the top 3 leaves, so that the rice can quickly recover.
Reasonable drainage. If it is cloudy after the flood has subsided, drain the water at one time. If it is sunny, the field should still retain the shallow water layer and drain it after the plant is restored for 1-2 days.
Disease prevention and treatment. After flooding rice fields, rice is prone to bacterial diseases such as bacterial stripe disease and bacterial blight. After washing rice leaves, immediately use 25% leaf extract or 20% leaf green double 100 grams or 20% thidium copper. 125 ml, sprayed with 60 kg of water.
Disaster relief. Do not carry out artificial seedlings caused by flooding, so that it can be automatically adjusted. At the same time, when washing the seedlings, pay attention to avoid spraying to the stems. For the rice with serious lodging, timely fix the leaves and clean the leaves, reduce the losses, and harvest at the right time. .
Early stage of rice panicle differentiation
Wash the water with water. Wash the rice leaves with water when the flood subsides to restore photosynthesis of rice leaves.
Timely stains . If it is cloudy after washing the seedlings, drain the water once. If it is sunny, keep the shallow water layer in the field, and check if the tip has dew in the morning, the base is hard, the tip has dew and the base is hard. Rice fields indicate that rice has been revived, and it can be used for 2 to 3 days in light field. Then, 4 to 5 kg of urea and potassium fertilizer are applied per mu of shallow water, and the cloudy or sunny day after dew is selected to be applied after 4 o'clock in the afternoon.
Disease prevention and treatment. Strengthen the control of rice blast, sheath blight, bacterial blight and bacterial leaf streak. Immediately after washing the rice leaves, use 40% rice bran or 25% prochloraz 100 ml, 20% jinggangmycin Powder 50 g, 25% leaf extract or 20% leaf green double 100 g or 20% thidium copper 125 ml, spray 60 kg with water.
Replanting and mitigating disasters . If the base of the rice stem is soft and has a wilting phenomenon, timely ploughing and replanting the early rice mid-maturing variety will be broadcast live before July 25.
Late rice seedling stage
The shade of the field. The roots of the seedlings after flooding are poorly viable, depending on the weather conditions when draining the seedlings. If it is cloudy, it can drain the water at a time, which is conducive to the rapid recovery of rice. If it is sunny, the surface should still retain the shallow water layer to avoid the dehydration and death of the seedlings. If it is found that there is a blade reel, it should be erected in time. Net, to prevent dead skin and dead seedlings.
Disease prevention and treatment. Immediately after washing the leaves, use 40% rice bran or 25% prochloraz 100ml, 20% jinggangmycin powder 50g, 25% leaf extract or 20% leaf green double 100g or 20% thidium copper 100ml, Apply 60 kg of water to the spray and try to apply it after 4 pm on cloudy or sunny days.
Replanting disaster reduction. If the seedlings appear wilting, harvest the early rice in time, and select the early rice mid-maturing variety to "turn over the autumn" live broadcast before July 25.
