Immersion germination in summer vegetables
When summer vegetables are raised, some species can be soaked with buds, such as solanaceous fruits and melons, and some vegetables cannot be soaked or germinated, such as beans. The soaking and sowing of solanaceous fruit and melon vegetables prior to sowing is not only to make the seeds germinate quickly and emerge early but also to prevent the seeds from decaying. In the cold climate around January, the superiority of soaking germination is even more obvious. Soaking seeds is to soak the seeds in clean water, stir them properly, and remove the seeds floating on them. If necessary, replace the water. When soaking, the amount of water can at least submerge the seed, but it should not be too much. When the seeds are fully swollen, remove the seed from the water and drain the excess water. If it does not germinate, it can be sown after being soaked, but if germination is used, germination can begin. The time for soaking varies depending on the species, such as 2-3 hours for cucumber, 3-4 hours for tomato, 4-5 hours for pepper, and 5-6 hours for eggplant. The soaking time is shortened with the increase of the water temperature, and the water soaking is generally normal temperature, or the water temperature may be appropriately increased. When the soaked seeds are sown, it is not always easy to spread them, especially solanaceous vegetables, which can be sown with mash and mix well. Germination is the soaking of seeds in an environment that maintains a suitable temperature to germinate the seeds. Appropriate germination temperature for solanaceous fruits and melons and vegetables is 25-30°C. At this temperature, 1.5-2 days for cucumber, 2-3 days for tomato, 5-7 days for eggplant and pepper, and more time for melon to germinate. long. Not only do you need to maintain temperature during germination, but you should also maintain good ventilation. When about 50% of seeds exposed white roots, germination stopped. Germinated seeds should be sown immediately, but due to cold air or continuous rain and snow at this time. Therefore, not only should the nursery bed be prepared in advance (even the electric heating line should be laid), but the timing of soaking and germination should be adjusted by watching the weather forecast.
