How to manage the temperature of peach trees?

Temperature management of peach trees: Although the annual average temperature of southern peach varieties is required to be 12 ~ 18℃, the optimum temperature for branch growth is 18 ~ 23℃. However, different phenological periods have different requirements for temperature, and the greenhouse should be managed according to these temperatures.

From germination to flowering, the temperature should be 10 ~ 15℃, the suitable temperature is 12 ~ 14℃, and the lowest temperature is 6℃. If the temperature is 0℃, the flowers will freeze.

The daytime temperature of flowering period is 15 ~ 25℃, and shall not exceed 25℃; Not less than 5℃ at night. The suitable temperature for pollen germination is 65438 08 ~ 25℃. At the high temperature above 30℃, pollen germination was inhibited, while at the low temperature of 4℃, only a small amount of pollen germinated after 48 hours.

The suitable temperature for young fruit development is 20 ~ 25℃, and the highest temperature is no more than 28℃. If the temperature exceeds 30℃, the sweetness of fruit will decrease. The temperature at night should be controlled at about 65438 00℃, with a minimum of 5℃.

When the temperature is 15 ~ 25℃, the fruit coloring is normal; Coloring is best at 22℃. Above 35℃, it will affect the coloring.
