Winter Tomato Planting Techniques

Tomatoes, also known as tomatoes , are grown in all parts of China. Winter tomatoes are best grown in a greenhouse or shed to provide a warm growing environment to ensure their yield and quality. Below, the editor will introduce the winter tomato planting technology , let’s take a look.

1. Variety selection

When planting tomatoes in winter, you must first choose varieties that are suitable for winter growth. Varieties with stronger cold resistance are more suitable for winter planting. These varieties include cherry tomatoes , cherry tomatoes , yellow cherry tomatoes, etc. When choosing varieties, it is necessary to fully consider local climate conditions, soil type and other factors to ensure that tomatoes can grow smoothly.

2. Temperature management

Tomato is a thermophilic crop, and its optimum growth temperature is 18-24 degrees. In winter, due to the low temperature, a series of measures need to be taken to increase and maintain the temperature in the greenhouse. For example, greenhouses or sheds can be used for planting, and insulation materials such as foam boxes and electric blankets can be used to increase the indoor temperature. At the same time, it is necessary to strengthen air vent management and control the temperature in the greenhouse through reasonable ventilation to avoid adverse effects of high or low temperatures on tomato growth.

3. Sowing and seedling raising

After preparing the soil and fertilizer, you can start sowing. Before sowing, soak the seeds in warm water to allow them to fully absorb water and swell. Then, spread the seeds evenly on the soil surface and cover them with a thin layer of soil. After sowing, keep the soil moist and avoid drying out. After about 7-10 days, the seedlings will break through the soil. At this time, weak seedlings, diseased seedlings and insect-infested seedlings should be removed in time to ensure the rational distribution of nutrients.

4. Moisture management

Tomatoes require less water in winter, but the soil should be kept moist. Generally, watering once a week is sufficient. More than half of the smart multi-span greenhouses use integrated water and fertilizer machines, which water the greenhouses at regular intervals and on sunny days.

5. Fertilizer management

Tomatoes require less fertilizer in winter, but they should still be fertilized appropriately. Generally, top dressing is done about one month after planting, and then every 10-15 days. Apply fertilizer in time during the fruit expansion period. When the first tomato fruit grows to the size of an egg, apply the first fertilizer and combine it with foliar fertilizer. After the first bunch of fruits is harvested, apply fertilizer for the second time.

6. Pest and disease control

In winter, tomatoes are susceptible to diseases and pests such as gray mold and viral diseases. Therefore, it is necessary to strengthen pest and disease control. Biological control methods can be used, such as releasing natural enemies such as ladybugs and centipedes to control pests. Chemical pesticides can also be used for prevention and control, but care must be taken to use them correctly according to the instructions to avoid harm to the environment and human health. At the same time, the humidity in the greenhouse should be lowered to reduce the occurrence of diseases and pests.

The above is an introduction to winter tomato planting techniques. When planting tomatoes in winter, you should choose varieties with strong cold resistance. At the same time, you should also consider local climate conditions, soil types and other factors to choose the most suitable varieties for planting.
