温度对设施栽培甜樱桃花芽物候期的影响

Effect of Temperature Regimes on Phenophases of Flowering of Sweet Cherries Cultivated in Glass House

利用3种温度模式管理温室栽培甜樱桃。结果表明:模式3与模式1相差较显著,模式3可以使甜樱桃花芽物候期提前,初花期早11 d,盛花期提前13 d。模式3与模式2相差不明显,初花期及盛花期分别比模式2提前3 d、4 d。揭帘时间和放帘时间对控制花芽物候期起决定作用。

Three temperature regimes were used to treat sweet cherries grown in glass houses. The results showed a clear difference between module 1 and module 3. Module 3 promoted early flowering of the treated sweet cherries with the initial flowering 11 days earlier and the full bloom 13 days earlier than that of module 1. Module 3 had a similar effect to module 2 with initial flowering 3 days earlier and full bloom 4 days earlier than that of module 2. Time of uncovering mat and coving mat on the glasshouse played a vital role in managing the phenophases of flowering.
