Cultivation Techniques of Tomatoes in Greenhouses with Warming in Winter

     Tomato is widely grown in my country, it has rich nutritional value, and the market demand is still quite large. With the development of agriculture and the advancement of planting technology, greenhouse planting has now become the main way of planting vegetables, which can adjust the vegetable production season, adjust market demand, and achieve annual production. So how to manage greenhouse tomatoes in winter? Next, let's learn about the planting and management techniques of winter greenhouse tomatoes.

     Greenhouse Tomato Temperature

    The suitable temperature for tomato growth is around 22°C, and the temperature in winter is very low, but greenhouse planting can effectively control the temperature, so in the cultivation of greenhouse tomatoes in winter, temperature control is a very critical issue. . In addition to ensuring the normal growth temperature of tomatoes, growers should try to control the temperature difference between day and night to about 12 °C. Otherwise the tomato plants may suffer from freezing damage.

     Top dressing of greenhouse tomatoes

    The growth period of tomatoes is relatively long, and the yield is high, and the demand for nutrients is large and comprehensive. Therefore, we need to control the proportion of nutrients in the fertilizer to ensure that it contains the nutrients needed by tomatoes. Before planting, enough base fertilizer should be applied, and in order to ensure the healthy growth of tomatoes, top-dressing should be done well during the growth period.

     Hanging vines and pruning

    When the plant grows to a certain height, if the vines are not hanged in time, it will easily fall and affect photosynthesis. Hanging vines is generally carried out when the first inflorescence is in bloom. First, above the tomato, pull a north-south wire, and pass one end of the plastic binding rope to the base of the plant and the other end to the wire. Later operations, you can use a rope around the vine.

Pruning and fork are carried out at the same time. Generally, a single trunk is used for pruning, only the main trunk is left, and all lateral branches are removed, which is conducive to strengthening ventilation and light transmission, preventing leggy growth, reducing unnecessary consumption of nutrients, and providing more photosynthetic products to the fruit. Don't be too late to fork, it is advisable to master when the lateral buds grow to 6 to 7 cm, and it should be carried out in the morning on a sunny day to facilitate wound healing.

     Watering of greenhouse tomatoes

     Tomatoes also require a lot of water. When planting, you should pay attention to watering to ensure that the soil is in a moist state. The watering method is small water drip irrigation. In winter, pay attention to the water temperature, and the water temperature should be controlled at about 10 ℃, otherwise the fruit quality of the tomato will be reduced.

     prune regularly

     The growth cycle of tomato is about 60 days. After the tomato grows stems and leaves, it is necessary to start pruning. You can use the method of interrupting and pinching. The side buds that grow out of the root base of the stem should be cut off, which can effectively prevent the invasion of pests and diseases. Generally, when the tomato just grows the first flower, in order for it to absorb the nutrients it absorbs, other side branches should be cut off as soon as possible. After waiting for the tomato to bear fruit, pinch off the main head above the fruit to control the insane growth of the plant.

To choose a moist environment and high-quality soil, the watering time is generally once every 7 to 10 days, and the most suitable watering time is before 10 in the morning. In the management of tomato, we should pay attention to the right medicine. Because of the need for fertilization, we should prune regularly after the tomato grows stems and leaves.
