How to grow tomatoes to get high yields?

Tomatoes are a common sight on people’s tables today. Not only do they taste sweet and sour, they are also round and cute in appearance, making them very popular among people. The growth and development process of tomatoes is divided into four stages: germination, seedling stage, flowering and fruiting stage, and fruiting stage. Let’s learn together how to grow tomatoes to achieve high yields.

1. Seed treatment

Warm water seed soaking method: Soak the seeds in 55°C warm water for about 15 minutes to effectively prevent ulcer diseases and leaf mold diseases.

② Trisodium phosphate seed soaking method: first soak the seeds in clean water for 3-4 hours, then add 10% trisodium phosphate solution and continue soaking for 20 minutes, and finally wash the seeds to effectively prevent and control viral diseases.

2. Germination

Soak the sterilized seeds for another 6-8 hours, wash them and place them in a 25℃ environment to germinate, maintaining appropriate temperature and humidity.

3. Preparation

Seedling raising facilities: Select seedling raising facilities according to the local climate, such as solar greenhouses, plastic greenhouses , multi-span greenhouses and hotbeds. Insect prevention and sunshade facilities are also needed in summer and autumn.

Preparation of nutrient soil: According to local conditions, such as field type, fertilizer , peat and rice husk ash, prepare nutrient soil in proportion to meet usage requirements.

4. Planting seeds

Sowing period: Determine the best sowing period based on local climate and seedling standards.

Sowing method: Sow after more than 70% of the germinated seeds turn white. Use sterilized seeds directly in summer and autumn. Before sowing, water the bottom thoroughly to moisten the bed soil more than 10 cm. After the water seeps in, sprinkle a layer of nutrient soil and cover it with nutrient soil after sowing. To prevent damping-off disease, sprinkle carbendazim and fine soil. Cover with mulch in winter and spring, and cover with straw in summer and autumn.

5. Seedling management

Environmental control: ① Temperature: shade and cool down in summer and autumn, and suitable management in winter and spring; ② Light: increase light in winter and spring, and shade in summer and autumn; ③ Water: water thoroughly for seedling transplanting, and water as appropriate.

Dividing seedlings: After the cotyledons are fully expanded, move them to the nutrient pots, mix them with 7 parts of sifted fertilizer soil and 3 parts of well-rotted manure, and add diammonium phosphate, wood ash and carbendazim.

Increase the nutritional area: When there are 3-4 leaves, increase the distance between seedlings, fill the gaps, and keep moisture and heat.

Fertilizer and water management: control water and fertilizer, and apply 500 times diluted Sea Elf Biostimulant (root application type) when the leaves have 3-4 leaves.

Hardening of seedlings: 15-20℃ during the day and 5-10℃ at night in early spring. Gradually remove the shade in summer and autumn and control the moisture.

Indicators for strong seedlings: In spring and summer, the seedling height is 25cm, the stem thickness is 0.6cm, and large buds appear; in summer and autumn, the seedling height is 15cm, the stem thickness is 0.4cm, and it takes shape within 25 days.

6. Planting

Land preparation and fertilization: The base fertilizer is mainly decomposed organic fertilizer , 2500-3000kg per mu, with appropriate amount of fertilizer.

Early-maturing varieties: apply 25-30kg of superphosphate, 15-20kg of potassium sulfate, and 10kg of urea.

Late-maturing varieties: control nitrogen fertilizer.

Mulching: half nitrogen fertilizer as base fertilizer and half as top dressing.

Phosphate fertilizer is applied throughout the layer, and superphosphate and organic fertilizer are applied in strips. After transplanting, apply 500 times diluted Sea Elf biostimulant (root application type) to stabilize the seedlings and apply a small amount of boron fertilizer.

Transplanting time: 25 days after sowing, when there are 5 leaves.

7. Field water and fertilizer management

Apply fruit-promoting fertilizer 7-10 days after transplanting, 500kg of liquid manure per mu. Apply 10-15kg of urea when the first bunch of fruits is enlarging. When the first bunch of fruits is about to be harvested and the second and third bunches of fruits are swelling, apply 1000 kg of liquid manure or quick-acting nitrogen fertilizer for three consecutive times to strengthen the seedlings, prevent premature aging, and improve quality.

During the topdressing period, use 300 times diluted Sea Elf biostimulant to promote rooting and seedling growth, balance nutrition, and protect flowers and fruits. In the middle and late stages of growth, spray 800 times the solution of Phosphorus and Potassium Source Library on the leaves to promote fruit development.

8. Plastic surgery

Tomatoes have strong growth potential and need pruning, branch cutting, and leaf thinning to regulate their growth and prevent clumping of branches and leaves, disordered plant shape, nutrient consumption, falling flowers and fruits, small fruit shape, and reduced yield and quality.

9. Pest and disease control

Common diseases include early blight, late blight, cotton blight, gray mold, leaf mold, bacterial spot, viral disease, root-knot nematodes, etc. Pests include American leafminers, whiteflies, aphids, and cotton bollworms. Use medication at the right time, focus on prevention, and adopt comprehensive management.

The above is an introduction to the key points of tomato cultivation technology. When planting tomatoes, you can choose the appropriate method according to the planting conditions, and then do the field work well, it is not difficult to increase the yield.
