High temperature, high humidity and heavy rain in summer are very likely to cause the occurrence and spread of vegetable seedling diseases, and have a great impact on summer seedlings of tomato, green pepper, eggplant and other solanaceous vegetables. To cultivate robust seedlings, we should focus on the following four points: 1 seedbed preparation. Choose loam with high topography, loose and fertile loam, and use the disease-free new soil or garden soil that has not planted solanaceous vegetables in 2 to 3 years as bed soil. The base fertilizer must be decomposed, and the seedbed, nutrient soil and seeds must be disinfected. 2 sowing. Seeds should be treated before sowing, often using warm soaking method or chemical dressing method, focusing on disinfection of viral diseases and bacterial diseases. The sterilized seeds are soaked in clean water, then wrapped in a damp cloth, and germinated under appropriate temperature and environmental conditions, and the seeds are sown after being shattered. Watering for 5 to 7 days before sowing. Sowing should be uniform, not too dense, otherwise it will make the seedlings grow long, causing the stems to be weak and lodging. Cover the soil after sowing, about 1 cm thick, and a small amount of water to keep the seedbed moist. When the newly emerged seedlings have a cap phenomenon, they can spray some water or sprinkle some moist fine soil to increase the humidity and help the seedlings to shell. 3 Strengthen seedling management. When the seeds break ground and germinate, weeding in time. Appropriate shading when the light is strong at noon, and strengthen the ventilation, not to apply nitrogen fertilizer to prevent the seedlings from growing. The seedbed should be kept moist, the soil temperature should be lowered, and the seedlings should be prevented from wilting due to lack of water. After the heavy rain, the sputum is drained in time to prevent the roots of the seedlings from being caused by excessive water in the seedbed. 4 control pests and diseases. Common diseases of solanaceous vegetable seedlings include rickets, blight, viral diseases, gray mold, etc. The pests include aphids, whitefly, and cockroaches. At the beginning of the onset of seedlings, spray 75% chlorothalonil 1000 times solution, or 70% dikesone 800 to 1000 times solution, or 65% Daisen zinc 1000 times solution, spray once every 7 to 10 days, even spray once ~2 times. If aphids and white meal are found, they can be controlled by cypermethrin or phoxim. If you find underground pests such as cockroaches, you can use phoxim drugs to lure with bait.
