How good is the temperature and humidity of planting peach trees in greenhouse?

What is the appropriate temperature and humidity for planting peach trees in greenhouse? The main points for attention in planting peach trees in greenhouse are as follows: first, the highest temperature is 25 ℃ and the lowest is 5 ℃ before flowering, and the suitable temperature for flowering is 20-23 ℃ and the lowest is 6 ℃. When the florescence encounters bad weather and frost may occur, the heating treatment of burning charcoal should be adopted. From anthesis to hard core stage, the highest is 25 ℃ and the lowest is 10 ℃, the highest is 28 ℃ and the lowest is 15 ℃ in hard core stage, the highest is 30 ℃ and the lowest is 15 ℃ in staining stage. Simple greenhouse and plastic greenhouse peach coloring period can remove the greenhouse film grass curtain, open field management, ventilation and transparent light, which is beneficial to improve photosynthesis and improve the internal and appearance quality of fruit. Second, humidity control production practice has proved that the suitable air relative humidity at flowering stage should be about 50%, 60%, too much humidity at flowering stage, which affects the powder of male buds and reduces the rate of fruit setting; the humidity is too small and the air is dry, which affects the life activities of pollen, and the fruit setting is also bad. In production, the method to control humidity is not only to reduce the number of irrigation and strengthen ventilation and dehumidification, but also to cover plastic film before flowering to reduce ground water evaporation and reduce air humidity. Irrigation during flowering is strictly prohibited, otherwise fruit setting will be affected. When dry, an appropriate amount of water can be sprayed on the plastic film to increase the indoor air humidity. More peach tree planting techniques
