Tomato, namely tomato, belongs to the genus Lycopersicon of Solanaceae. After flowering, pick the seeds when they turn yellow and dry, and then take out the seeds.
Generally, the flowering of tomatoes can be intrageneric hybridization, and some are interspecific hybridization. Cross-pollination is generally needed, but some can seed themselves, and when they mature, they will crack themselves, and very small seeds can be seen inside.
Tomato seeds are spread by animals. After animals eat tomatoes, the seeds inside are difficult to digest, so they are excreted. At present, a bag of 5g seeds is probably from 30 yuan, and 1 1000 autumn seeds are from 450 yuan. 350 yuan's seeds in Weifang, Shandong Province have the same specifications, and 450 yuan's early spring seeds have the same specifications.
Tomato seeds can be planted in February, May, July-August and August-September.
Method and technology for plan tomato seeds
Tomato seeds can be exposed to the sun and scorching sun for one day, and disinfection can improve the germination rate. Then, prepare fertile and loose soil rich in humus, spread a layer of screened fine soil on it, spray it a little, then spread the seeds evenly on the seedbed, cover it with plastic film and compact it with stones.
After about 3-5 days, tomato seeds will germinate. After the embryo leaves grow, open the plastic film in time for ventilation. When the real leaves appear, you can spray a layer of light manure and water fertilizer with a watering can to promote growth. At this time, if the soil is dry, you need to spray water in moderation.
Matters needing attention in tomato sowing
Tomatoes like warm environment, the suitable growth temperature is between 20℃ and 25℃, and the optimum soil temperature for root growth is between 20℃ and 22℃. In addition, it is also a light-loving plant, suitable for growing in the sun, but some varieties like short sunshine, so to control the light time, tomatoes need more water, but they are not resistant to water and humidity, and should be watered appropriately.
