1.桃树萌芽期:白天13℃~18℃,夜间6℃以上,相对湿度80%以下。花期:白天14℃~17℃,夜间5℃以上,相对湿度50%~60%。果实膨大期:白天15℃~25℃,夜间10℃~15℃,相对湿度70%以下。果实近成熟:白天25℃~30℃,夜间15℃~17℃,相对湿度70%以下。萌芽期和开花期是温度控制的关键时期,萌芽期温度过高降低坐果率,开花期温度过高过低都影响授粉受精。各生育期,白天温度接近最高限定温度时应放风,通常先放顶风,如温度继续升高,可放脚底风。夜间温度降到5℃以下时,如时间较长,用火炉或火盆加温,
1. Peach germination period: during the day 13 ℃ ~ 18 ℃, night 6 ℃ above, relative humidity below 80%. Flowering: during the day 14 ℃ ~ 17 ℃, night 5 ℃ above, relative humidity 50% ~ 60%. Fruit enlargement period: during the day 15 ℃ ~ 25 ℃, night 10 ℃ ~ 15 ℃, relative humidity below 70%. The fruit is nearly mature: 25 ℃ ~ 30 ℃ during the day, 15 ℃ ~ 17 ℃ at night and relative humidity less than 70%. Germination and flowering is the key period of temperature control, the embryo temperature is too high to reduce the rate of fruit set, the flowering temperature is too low too high, affecting pollination and fertilization. Each growth period, the daytime temperature should be close to the maximum temperature of the wind, usually put the top wind, such as the temperature continues to rise, you can put the foot of the wind. Night temperature dropped below 5 ℃, such as a longer time, with a stove or brazier heating,
