Early spring vegetable seedbed disease prevention technology

<

There are many seedbed diseases, such as damping-off disease, blight, gray mold, anthracnose, and wilt disease. The control methods are as follows: 1. Seed disinfection is soaked in warm water of 55 degrees for 15 minutes to kill the seeds attached to the seed surface. The germs at the same time act as germination. For damping-off disease, tomato early blight, and eggplant brown leaf disease, formalin 100-fold liquid soaking can be used for 10 to 15 minutes and then rinsed with water, dried and sown. The anthrax can be soaked in 100-fold solution of copper sulfate for 5 minutes. Second, bed soil disinfection with 70% pentachloronitrobenzene powder and 65% zein zinc WP or thiram WP can be mixed in equal amounts, 8-9 grams per square meter seedbed medication, and then with 15 kg of dry fine soil Mix well and cover soil. It is also possible to use 5 grams of 70% dexamethasone per square metre and mix it with doubling fine soil and sprinkle it in the seedbed. If the bed soil is relatively dry, it can be used 200-400 times that of zesin ammonium, and 2-4 kg per square meter of bed soil, which can not only disinfect but also play the role of moist bed soil. Third, careful seedling nursery bed temperature required to maintain 30 degrees before emergence, 20-25 degrees after emergence. Sunny temperature control 25 degrees, cloudy 16 degrees, night 7-10 degrees lower than the day. Bottom water to soak the topsoil by 10~13 cm, so that it is wet during the day and dry in the evening. It is sunny and wet and cloudy. After the seedlings are unearthed, the seedlings are often planted by low temperature and controlled watering. The seedlings are planted 7 days before transplanting, and the open-air seedlings are planted at night without weather and frost. Fourth, timely medication every 10-15 days, with 65% dexamethasone 600-800 times liquid spray 1, can also be used 50% dexamethasone and 70% thiophanate 1000 times alternating use. When individual strains appear on the seedbed, the diseased plants should be removed immediately and sprayed in time to prevent the spread of the disease.
