What temperature and humidity are suitable for growing peach trees in a greenhouse?
Key points for growing peach trees in a greenhouse:
1. Temperature control
Before flowering, the maximum is 25°C and the minimum is 5°C; during the flowering period, the suitable temperature is 20-23°C, with a minimum of 6°C. If bad weather occurs during the flowering period and frost may appear, heating treatment by burning charcoal should be adopted. From after flowering to the pit-hardening stage, the maximum is 25°C and the minimum is 10°C; during the pit-hardening stage, the maximum is 28°C and the minimum is 15°C; during the coloring stage, the maximum is 30°C and the minimum is 15°C. For simple greenhouses and plastic tunnels, during the peach coloring stage, the greenhouse film and straw curtains can be removed for open-field management, providing ventilation and light transmission, which helps improve photosynthesis and enhance the internal and external quality of the fruit.
II. Humidity control
Production practice has proven that the suitable relative air humidity during the flowering period should be about 50%-60%. If humidity is too high during the flowering period, it affects pollen release from the male buds and reduces the fruit-setting rate; if humidity is too low and the air is dry, it affects the life activities of pollen, and fruit setting is likewise poor. In production, in addition to reducing the number of irrigations and strengthening ventilation to remove moisture, methods for controlling humidity also include covering the ground with plastic film before flowering to reduce water evaporation from the ground and lower air humidity. Irrigation during the flowering period is strictly prohibited, otherwise it will affect fruit setting. When dry, an appropriate amount of water can be sprayed onto the plastic film to increase the air humidity inside the greenhouse.
