A few days later, tomatoes germinated and unearthed.

It usually takes 7 days to 14 days for tomato seeds to grow after germination, and then it takes 7-9 days to grow real leaves. Tomatoes are planted in the open air in spring. Generally, seedlings are planted in February-March in the north, and can be planted and cultivated in July-early August in the south in autumn. They can be planted by planting in deep, drained and breathable soil and keeping the soil moist.

A few days later, tomatoes germinated and unearthed.

1. How long does it take for tomato seeds to germinate? Tomato seeds are usually sown in spring and autumn. As long as the soil is wet, it will germinate in a week or so. Tomato seeds can be planted directly in the ground, but germination will be slow and the survival rate will be low.

2. Germination temperature of tomato seeds: The optimum germination temperature of tomato seeds is 25℃~ 30℃. As long as it exceeds this range, it will affect the differentiation of seed buds. When the ambient temperature is inappropriate, it can be kept in a greenhouse or indoors.

3. Germination and excavation of tomato seeds: Generally, tomato seeds should be soaked for about 10 hour before planting. When the temperature, humidity, light, moisture and other growth conditions are suitable, tomatoes will germinate in about 3 days.

4. Method of accelerating germination of tomato seeds: Generally, tomatoes are accelerated by soaking seeds. First, soak the seeds in clear water for two hours, then put them in warm water at about 50℃ and stir for about 15 minutes, then stop stirring and soak them for four hours before taking them out. Even if the seeds are sown, they will germinate quickly.

Planting time

The best planting time of tomato is August-September in autumn, because the temperature in autumn can be kept above 10 degrees, and the light and humidity are suitable, which is beneficial to improve the germination rate of tomato, but attention should be paid to adjusting the planting time according to the local weather conditions.

Tomato planting method

1, site selection and seed selection

Choose a plot with deep soil layer, good drainage and irrigation, and good ventilation to plant tomatoes. Choose varieties that are disease-resistant, high-quality, high-yield, resistant to storage and transportation, good in commodity and suitable for market demand, such as Jintiewang.

Step 2 soak the seeds for sowing

Soak the seeds in clean water for an hour or two, then put them in warm water at 50-60℃ and stir them constantly to prevent the seeds from being scalded. The whole journey is maintained at 15 minutes. Finally, the seeds can be planted after soaking for 3-5 hours. Seedbed sowing should not be too dense, and about 30 grams per square meter can be sown. After sowing, water should be used to keep the soil moist, and the temperature should be controlled between 22-28℃, and the seeds can germinate in about 3-4 days.

Step 3 plant

The planting time is from early April to early May, the plant spacing is controlled at 50-60 cm, the row spacing is controlled at 1.2- 1.3 m, and it is appropriate to plant 2000 tomato seedlings per mu. At the same time, it is better to plant after 4 pm on sunny or cloudy days. After planting, the planting water should be thoroughly irrigated in time, and then irrigated after 3-5 days 1 time.

4. Tian Tuan management

(1) Water more in dry season and less in winter. Drainage measures should be taken in rainy season to avoid root rot caused by excessive water accumulation.

(2) When the tomato plant is about 30 cm high, it should be erected in time, and the vines should be tied. Scaffolding usually adopts herringbone brackets. After laying the bracket, fix the dried tomatoes on the bracket with a plastic rope, and trim one stem, with 5-6 ears per plant and 4-5 fruits per ear.

(3) In addition, the redundant side branches, abnormal fruits, diseased fruits and redundant fruits should be removed in time. Remove the old leaves and diseased leaves in time at the later growth stage, reduce nutrient consumption and disease spread, and enhance ventilation and light transmission.
