Greenhouse vegetable temperature requirements

Greenhouse vegetables have different requirements for temperature. Here are some suitable temperatures for several vegetables. For reference only:

The pepper is hi and high temperature, the germination temperature is 30--45°C, the room temperature is 26--30°C during the day, 18--22°C at night, and the seed cannot germinate at a temperature below 15°C. Flowering can not be fertilized. The ground temperature should be maintained at 20-25°C, below 18°C, and poor growth.

Tomato high temperature, germination at 25--30 °C is the best, fertility room temperature is 27 °C during the day. The boundary temperature for cultivation is 10°C, the temperature is 5°C, and the minimum temperature for root growth is 0°C. The most suitable temperature is 28°C and the highest temperature is 38°C.

The celery likes to be cool, the fertility room temperature is 20--22°C during the day, 15-18°C at night, and the temperature difference between day and night is 4--5°C. The ground temperature is at 18--20°C, and the minimum temperature cannot be lower than 3--6°C. Late 6-8 °C, otherwise it can not grow and develop.

Cucumbers have strict temperature requirements. The suitable temperature is 24-26°C during the day and 14--15°C during the night. The limit of the ground temperature is 10--12°C, and the growth stops below 10°C. Root activity above 30°C occurs. Weak, the leaves shrank. The seedling period and growth period must not be lower than 18°C, and the optimum temperature is 20--23°C.
