温度调控对北方盆栽蓝莓开花的影响

摘要

Two cultivars of potted blueberries in Northern China ,Blomidon and Northern blue were selected as the research objects to investigate the effects of temperature on flowering .The results showed that :The chilling re‐quirement for Blomidon and Northern blue is 1200 hours and 1000 hours ,respectively .When the chilling require‐ment were satisfied ,the dormant status of the potted blueberries could be broken by temperature control ,and they could flower in advance .%以北方盆栽蓝莓美登和北蓝为研究对象，通过人为温度控制，促使盆栽蓝莓提前开花。研究表明，盆栽美登（Blomidon）在需冷量达到1200h ，盆栽北蓝（Northern blue）在需冷量达到1000h情况下，可以通过温度调控，打破盆栽蓝莓休眠期，达到提前开花的目的。
