How many days will it take for tomato seeds to germinate?

Tomato seeds usually germinate in about one to two weeks. The specific time depends on the planting time and the planting soil. When planting, try to choose soil with deep, fertile soil and strong water retention capacity. The seeds need to be treated before planting. After soaking the seeds in clean water, soak them in 55°C hot water for 15 minutes, and then soak the seeds for 3-4 hours to maintain the water temperature.

What should you pay attention to when growing tomatoes? Let the editor tell everyone about it.

1. Requirements for environmental conditions

1. Temperature: The temperature suitable for tomato development is 24°C to 26°C. Tomatoes must be allowed to develop within this temperature.

2. Light: Tomato is a crop that needs light and is very sensitive to light. Sufficient light will allow tomatoes to grow vigorously, with thick stems and strong resistance to stress; insufficient light will cause tomatoes to stunt development, and in severe cases, there may be a risk of leaf loss, deflowering, or even fruit rot.

3. Water: Tomato is a deep-rooted crop. Tomato is afraid of drought and flooding, but it needs drainage very much, so the water given to tomatoes cannot be more or less. It must be Remember to drain water in time.

2. Tomato cultivation technology

1. Sowing date: Tomatoes are generally planted in January and February, or in July and August; if planted in summer, due to the temperature Because of its relatively high height, tomatoes do not develop very well, with small rhizomes and many flowers, and it is difficult to produce fruits. Winter sowing is only suitable for low-altitude hilly areas or southern plains. Sow seeds in October to early November.

2. Seed disinfection: Seeds must be disinfected before sowing. During the disinfection period, wrap the seeds with gauze and soak them in 50℃ water for 10 minutes, or soak them in 10% sodium phosphate solution for 20 minutes. Rinse with clean water and soak in 30°C warm water for 23 hours. Take out the dry ones.

3. Seedling management: Determine based on climatic conditions such as winter planting or early spring seedling raising, small arch sheds for cold protection, and film covering. Summer and autumn seedling planting focus on preventing high temperatures and heavy rains, and use sunshade nets to cover seedlings. During the seedling cultivation process, appropriate top dressing measures must be taken, and more watering, rotten urine or leaching of 0.1% urea water must be used. At the same time, chlorothalonil needs to be sprayed 600 times and dimethoate about 1,000 times during the seedling stage.

3. Soil preparation and planting

Before planting tomatoes, you should choose a place to plant rice, or plant solanaceous plants and other crops. Before planting, 1,000 kilograms of pig manure and 50 kilograms of superphosphate can be added to the basic fertilizer. The spacing between plants is about 20 centimeters, and there are about 3,000 plants in one acre. In winter, tomatoes need to be covered with mulch. The inconvenience caused by top dressing is particularly emphasized that we need to apply a base fertilizer to tomatoes once, with delayed effect organic fertilizer as the main fertilizer. Other measures are exactly the same as open field cultivation.

IV. Field management

1. Fertilization: Tomato is a vegetable with continuous growth and high seed setting rate. In addition to applying enough base fertilizer, top dressing is also essential, about once every 10 days. Before each top dressing, the amount of urea per acre should not exceed 5 kilograms. When the first ear becomes larger, how much fertilizer should be added depends on the situation. When the second and third ears become larger, it is necessary to increase nutrition, mainly adding an appropriate amount of phosphorus and potassium fertilizer. Later top dressing must ensure the healthy growth of the plant. On the premise that sufficient base fertilizer is applied, the total amount of top dressing for tomatoes per acre must be 70 kg of urea and potassium fertilizer, 50 kg of urea, or 100 kg of compound fertilizer and 30 kg of potassium fertilizer.

2. Water management: Keep the fields moist and water when you see the soil is dry. Keep the ditch moist for 1 to 2 hours after it drains dry, keeping the soil moist. Because irrigation can easily cause the spread of bacterial wilt, it should be used sparingly.
