How to germinate tomato seeds? A detailed guide to the latest methods
Tomato growing mainly relies on raising seedlings from seed; other methods are rarely heard of, because seed propagation is convenient and efficient, and it is the main effective method. In modern agriculture, in order to achieve uniform emergence after sowing, disinfect and sterilize, and reduce disease, seeds need to be germinated before sowing, breaking seed dormancy, and then sowing is carried out. What I mainly want to introduce now is the method of seed germination, how it should be done, and I hope it will be helpful.
1. Germination requirements
Provide a suitable temperature and humidity environment for germination. Generally, tomato seeds need a temperature between 20 and 25 degrees, and the humidity must be above 80%. In addition, because in a warm and humid environment there will be mucus after being kept for a period of time, every day they must be taken out and cleaned thoroughly, then after draining off the water, wrapped again in a clean wet cloth, and then germination continued. In addition, they should also be turned over frequently, so that air circulation can be ensured. Before germination, the seeds must be soaked in chemicals or stirred in hot water for sterilization, and germinated only after disinfection, to avoid the seedlings carrying bacteria.
2. Tile pot germination
After disinfecting the seeds, clean them thoroughly, and after draining, wrap them well in soaked gauze, then place them in a tile pot. Some dry grass can be placed under the tile pot to prevent moisture, then cover them tightly with wet gauze; do not use too little gauze, preferably 3 to 4 layers of gauze. After that, place the tile pot in a warm place, and germination can begin; after about a few days they will sprout.
3. Sand germination
The advantage of sand germination is that sand is moist and well aerated, reducing the possibility of disease occurring at the seedling stage, and sprouting is relatively fast. First wash the sand, then expose it to the sun for disinfection, and then collect it for use. After the seeds are disinfected, mix the seeds and sand together in a ratio of 1:1.5, and put them in a tile pot. Then add a layer of wet sand on top, place it in a warm place; a tile pot is chosen because it has good air permeability.
3. Insulation germination
Germinate directly in an incubator; generally these are electronic incubators with adjustable temperature, and at the beginning they may need to be set at around 25 to 28 degrees. When most of the seeds have broken through their coats, the temperature should be lowered; the parts that have just broken through need a slightly lower adaptation temperature, roughly between 20 and 24 degrees. After most of the seeds have turned white, they should be moved to a refrigerator for dormancy-breaking treatment, kept at a low temperature of 5 degrees, to sprout as quickly as possible.
For tomato seed germination, they must first be disinfected, and then a suitable temperature and humidity must be provided for germination. Therefore, no matter which method is used, a suitable germination environment must be provided, so that the germination effect can be ensured, germination can be fast, and sprouting can be uniform.
