How do you plant tomato seeds?

Do you know how to plant tomato seeds? This requires some planting techniques, otherwise your tomatoes will not grow very well, the editor has also planted a lot of tomatoes, growing well all the time. Below, the editor of Qiannong Network will introduce to you how to plant tomato seeds.

Requirements for planting environment of tomatoes

1. Temperature: tomato is a temperature-loving vegetable. Under normal conditions, the optimum temperature for assimilation is 20: 25 ℃, and the optimum soil temperature for root growth is 20: 22 ℃. Increasing soil temperature can not only promote root development, but also significantly increase the content of nitrate nitrogen in soil, accelerate growth and development, and increase yield.

2. Light: tomato is a light-loving crop, the light saturation point is 70000lx, and the suitable light intensity is 30000~50000lx. Tomato is a short-day plant, which basically requires short-day sunshine in the process of changing from vegetative growth to reproductive growth, but the requirement is not strict. Some varieties can bud and blossom in advance under short-day sunshine, while most varieties blossom earlier under 11-13 h sunshine. Plant growth is robust.

3. Moisture: tomatoes need more water, but they do not have to be irrigated frequently. Generally, the soil moisture is 60% 80% and the air humidity is 45%. The high humidity in the air not only hinders the normal pollination, but also causes serious disease under the condition of high temperature and humidity.

4. Soil and nutrition: tomato does not have strict requirements on soil conditions, but in order to obtain high yield and promote good root development, fertile loam with deep soil layer, good drainage and rich organic matter should be selected. PH6~7 is suitable for soil acidity and alkalinity, and over-acidic or over-alkaline soil should be improved.

Planting method of Tomato seed

1. Put the small tomato seeds that have been dried on the paper and expose them to the hot sun for another day before planting (eliminate germs and viruses, increase the germination rate), and then disperse the glued seeds into grains for spare. This is a key step in how to plant tomato seeds and cannot be omitted.

2. Rake flat leeward and sunrise, rich in humus, fertile, loose and suitable seedling soil "bed", and then spread a layer (20 mm thickness) of fine soil sifted by 5X5 mm sieve.

3. First, spray clean water evenly on the seedling bed, then spread the small tomato seeds evenly on the seedling bed, then put on a circular bamboo skeleton, cover the plastic film, and compact the periphery with stones and soil (moisturizing and heat preservation).

4. The seeds will sprout after 3-5 days (temperature factor). When the embryo leaves grow, open the plastic film once in the morning and afternoon during the day to give them fresh air.

5. When the real leaves appear, give them a careful spray with a spray can to promote the growth of light feces and urine.

6. When the soil in the culture bed is short of water, it should be replenished with a spray can in time.

In this way, it takes less than a month to take the seedlings and transplant them into the planting field (using a flat shovel to cut an inch of thick culture soil to get seedlings, and transplanting with soil to turn green earlier). After understanding how to plant tomato seeds, you can also try to plant them according to Xiaobian's experience to see how effective it is. I hope you can taste the tomatoes you grow.
