In gardening activities, sowing in a seedling tray is an important step in cultivating healthy and strong seedlings. In order to improve the germination rate of seeds, every detail of sowing is crucial. The following will discuss in detail the key details that need to be paid attention to during the sowing process in the seedling tray.First of all, choosing a suitable seedling tray is the basis. The seedling tray should have good air permeability and drainage to ensure that the seeds can get enough oxygen and avoid water accumulation during the germination process. At the same time, the size and number of holes in the seedling tray should be reasonably selected according to the type and number of plants planted.Before sowing, the preparation of the seedling tray is equally important. The ground needs to be flat to ensure uniform watering, thereby improving the germination rate of seeds. Next, evenly spread a layer of substrate in the seedling tray. The choice of substrate should be determined according to the needs of the seeds. It is usually required to be fine, loose, soft, breathable, water-retaining and contain micro-fertilizer. The height of the substrate should account for about half of the hole tray. Too much or too little will affect the germination of seeds. After laying the substrate, water it thoroughly to make the substrate reach the appropriate humidity.When sowing, only one seed should be sown in each hole to avoid competition between seeds and reduce the germination rate. For small seeds, such as petunias and sunflowers, since they need light to germinate, they do not need to be covered with soil. Just make sure that the seeds are in full contact with the substrate. Larger seeds need to be covered with a thin layer of soil, about 1-2 times the diameter of the seed.Maintenance after sowing is also critical. Water it again, and check the humidity of the substrate every day in the next few days, replenish water in time, but avoid excessive watering to cause water accumulation. At the same time, pay attention to controlling temperature and light conditions. Maintaining a suitable temperature helps seed germination, and proper light can promote photosynthesis of seedlings and enhance their growth. But be careful to avoid high temperature exposure to avoid damage to the seedlings.In addition, keeping the seedling tray clean and sterile is also an important factor in improving the germination rate. Before sowing, the seedling tray and substrate should be thoroughly disinfected to kill possible pathogens and insect eggs.In summary, the details of seeding in the seedling tray are crucial to improving the germination rate of seeds. From choosing the right seedling tray and substrate to fine sowing and maintenance management, every step needs to be taken seriously. Only in this way can healthy and strong seedlings be cultivated, laying a solid foundation for subsequent gardening activities.
