1, nurture strong seedlings. Select paddy fields or paddy fields for nursery beds, and disinfect the soil with 0.5 kg of Dirkson per acre. Before sowing, the seeds were soaked in warm water at 55°C for 10 minutes, and then seeded with 50% carbendazim WP at 0.3%-0.5%. 2, cultivation and management. Rational rotation, full base fertilizer, apply more organic fertilizer, nitrogen, phosphorus, potassium fertilizer ratio of 1:0.4:1.2. Starting from the ditch, reasonable close planting, the flowering period, the results of each spraying a single potassium dihydrogen phosphate, per acre of potassium dihydrogen phosphate 100 grams of water spray 60 kg, can improve the plant's disease resistance. 3, spraying control. Once the disease occurs, the diseased plant should be removed and burned in time, and lime powder should be disinfected at the diseased point, or sprayed with 75% chlorothalonil 1000 times solution to prevent the spread of the disease. To use the appropriate agent to control: 1 damping-off disease and blight: In the early stages of the disease with 75% chlorothalonil 600 times or 95% of the enemy to spray 1000 times enemies. 2Virus disease: transmitted by locusts and susceptible to disease. The locusts can be killed by 2.5% enemy kill or Uranus 3000 times solution or vegetable and Fruit phosphorus 1500 times, and spraying disease with 1000 times solution of plant disease or 2% virus α500 times. Area. 3 Fusarium wilt: Pathogens can overwinter in soil or on seeds. Therefore, we must use resistant varieties, can also use 50% carbendazim or 50% thiophanate-methyl 500 times soaking root. The above liquid sprayed once every 7-10 days, even sprayed 2 times, the effect is very good.
