Do Meisheng tomatoes overwinter? Management temperature for overwintering tomatoes

Hello, this one is grown in greenhouses. It does not matter. You can choose to buy according to your actual needs.

Tomato seedlings have different temperature requirements at different times. After sowing, in order to promote the emergence of seedlings, the temperature of the seedbed (soil temperature) should be controlled at 20 25 night temperature not lower than 20.

After the emergence of seedlings, the mulch film should be removed in time, and in order to prevent growth, the temperature should be appropriately reduced, the day temperature should be 22-25, and the night temperature should be 13-15; In order to promote the slow seedling after seedling division, the temperature can be appropriately increased, and the day temperature should be 25-28 and the night temperature should be 15-18. In order to prevent the growth of seedlings, the day temperature should be 20-25, and the night temperature should be 10-15. The seedlings were refined, 18 20 during the day, and 7 8 at night, which enhanced the cold resistance of the seedlings.

The suitable temperature of the flowering period is 25 28, and it can bloom and bear fruit normally in the range of 15 30.

During the fruit development period, the temperature should be below 35, preferably below 30. For the fruit to develop well, the temperature during the day must be the temperature at which strong photosynthesis is maintained, i.e. a maximum of 28 and a maximum of 25, and a night temperature between 12 and 17.

1. The slow seedling period after tomato planting in winter is in the cold season, and the greenhouse temperature is mainly suitable. It is conducive to the growth of tomatoes, and the light and humidity in the shed are adjusted by the injection of rotten slaps, and the new high-lipid film can be sprayed in time to effectively prevent the water on the ground from evaporating, and the moisture of the seedling body from transpiring, shorten the seedling period, so that the plants can quickly adapt to the new environment and grow healthily.

2. According to the growth needs of tomatoes, reasonable watering, fertilization, weeding, pest and disease control, at the same time, the old leaves and yellow leaves of the lower part of the plant should be removed and brought out of the shed for deep burial, and the new high-fat film is sprayed in the greenhouse to form a protective film to prevent and control the invasion of airborne pathogens.

3. In order to improve the fruit setting rate of tomatoes in greenhouses, it is generally sprayed before flowering, young fruit stage and fruit expansion period to enhance the quality of pollen fertilization, improve the cycle fruit setting rate, promote the development of fruit and fruit seeds, prevent the occurrence of cracked fruits and deformed fruits, improve the quality of tomatoes, and produce abundant yields.

1. Low temperature and high humidity are easy to cause diseases, so attention should be paid to heat preservation, ventilation and moisture discharge.

2. In the protected area, the ventilation conditions are poor, the pollination is not good, and the artificial pollination should be done.

3. Try to increase the light time and increase the photosynthetic products.

4. Remove the lower old leaves in time to increase light transparency and air circulation.
