1. Rapidly reduce the accumulation of stagnant water in the field, keep the shallow water level at 10-20 cm, and keep the water level in the depth of 30-50 cm. 2. Apply a top-dressing fertilizer to the whole field at a rate of 20 kg per mus of urea, 20 kg of potassium sulfate, or 40 kg of 45% compound fertilizer. When fertilizing, it is important to pay attention to the loss of fertilizer in the fields of Sham Shui Po. It is advisable to fully mix the chemical fertilizer with the river mud to make a fat ooze and then apply it to the paddy fields. Fertilizers should also be avoided at noon in the hot sun. It is advisable to release the field water before the fertilization in the conditional field, so that the fertilizer can be absorbed into the water, and then watered to the original depth. 3, do a good job of pest control work. After the rain, many corruption diseases in Putian and umbilical black rot in our province were seriously injurious, resulting in the death of lotus leaves. The effect of simple foliar spraying on prevention and treatment of spoilage diseases is not significant. The current disease strains with severe disease in Tanaka must be removed from the roots and carbendazim or hymexazol should be sterilized in the soil. When the number of diseased plants is large, one by one Remove roots and apply medication to the entire field. For specific operations, use 50% carbendazim 500g or 99% hymexazol 100-150g per acre per acre, mix wet soil 25-30kg, and make stuffy stuffy stuff for 3 to 4 hours to make a medicine and soil conglomerate. Pocket. After 3 days, foliar and petioles were sprayed with 70% thiophanate-methyl 800x, 50% carbendazim 600x, or 99% hymexaz 2500x, once every 6 days. Anti-umbilical black rot can be controlled by 50% carbendazim WP 1000 times, 80% mancozeb WP 800 times, 250 gram/ liter propiconazole EC 1000 times foliar spray. At present, if fine weather persists, we must also guard against the outbreak of Spodoptera litura. Before the young instar larvae of Spodoptera litura do not disperse, apply 3.2% beta-cypermethrin-methyl avermectin benzoate microemulsion, or 10% Chlorantraniliprole (Kangkang) 3000 times, or 25% diflubenzuron 3500 times solution was sprayed. Chemical pesticides are prone to phytotoxicity to the lotus leaf, and must be used to determine the concentration. Do not arbitrarily increase. 4. Do a good job of preventing pests in the field. The pests that are seriously harmed in the fields after the rain are mainly duckweed, sponge and snails. Lotus leaves are more sensitive to herbicides and must be used with caution. Can spread urea or ammonium bicarbonate and other nitrogen fertilizer on duckweed to inhibit the growth of duckweed; can be poured in the sunny pouring of copper sulfate solution to prevent water sponge, copper sulfate dosage according to the water depth, the amount of land per mu, according to every 10 cm water depth 0.5 The amount of kilograms of copper sulphate is calculated once every 7 days for a total of 2 or 3 times; 20 kilograms of tea seed cake per acre is used to prevent and control the rice food root venom and snails. After mashing and soaking for 24 hours, even slag is poured with juice. splash.
