1、 Planting method

1. Seed treatment: tomato seeds need to be soaked before sowing. Generally, soak it in clean water, change it into 55 ℃ hot water after taking it out, control the water temperature, and soak it in warm water for 3-4 hours after soaking for 15 minutes, which can prevent some diseases. In addition, soaking seeds with trisodium phosphate solution can also be used. After soaking the seeds, it is necessary to accelerate germination. Squeeze the juice with frozen potato tubers, put the seeds in it, take out the seeds the next day, put them on the cloth, cover them with plastic film to moisturize, pay attention to ventilation, and put them in a warm place to accelerate germination

2. Soil preparation: nutrient soil needs to be prepared before sowing. The porosity of the soil is about 60%, preferably neutral or slightly acidic. Add an appropriate amount of compound fertilizer to ensure that the soil contains a certain amount of nitrogen, phosphorus and potassium, which is helpful for the growth of plants. After the soil is prepared, it should be tiled on the seedbed

3. Sowing methods: there are three sowing methods of tomato, namely drill sowing, on-demand sowing and sowing. Generally, it is planted in the way of on-demand sowing. The seeds are sown on the surface of the soil, and then covered with a layer of fine soil. The thickness of the soil is less than 1 cm. Spread carbendazim powder on the seedbed to prevent sudden collapse. In winter and spring, it is necessary to cover with plastic film. In summer and autumn, it is necessary to pull up the shading net. After the seedlings grow, remove the plastic film or shading net

4. Follow up maintenance: true leaves will appear in 7-9 days after sowing, and the temperature should be kept between 25-28 ℃. Because the drought tolerance of the plant is relatively strong, and it is not waterlogging resistant, it is necessary to control the watering and do not water too much. Fertilizer should be applied properly during the growth period, but do not apply nitrogen fertilizer. Phosphorus and potassium fertilizer are generally used. Seedling fertilizer can be applied after planting
