摘　　要：以半高丛蓝莓品种"北陆"为试材,在掌握蓝莓物候期的基础上,研究了不同温度、湿度、光周期对"北陆"蓝莓花芽分化的影响,确定其花芽分化进程所需温度、湿度、光周期的阈值及最佳条件,为蓝莓种植特别是设施反季节栽培熟期控制提供技术参考。结果表明:"北陆"蓝莓花芽分化初期所需最适条件为温度20℃、湿度60%、光周期少于12h-短日照;花序原基分化期所需最适条件为温度15℃、湿度80%、光周期少于12h-短日照;萼片原基分化期所需最适条件为温度15℃、湿度80%、光周期少于12h-短日照;花冠原基分化期所需最适条件为温度12℃、湿度70%、光周期少于12h-短日照;雄蕊原基分化期所需最适条件为温度15℃、湿度80%、光周期少于12h-短日照;心皮原基分化期所需最适条件为温度20℃、湿度60%、光周期少于12h-短日照。Taking half-high bush blueberry ＇Northland＇ as test materials,on the basis of mastering blueberry phenophase, the effect of different temperature, humidity, photoperiod on ＂Northland＂ flower bud differentiation were studied, the required temperature, humidity, light cycle threshold and optimum conditions of its flower bud differentiation process were determined,to provide technical reference to blueberry cultivation especially for the blueberry planting facilities anti- season cultivation ripening control management. The results showed that,the best condition for early stage of flower bud differentiation of ＇Northland＇ blueberry were temperature 20℃, humidity 60 %,photoperiod less than 12 hours-short day; the best condition for flower primordium differentiation were temperature 15℃, humidity 80%, photoperiod less than 12 hours-short day; the best condition for sepal primordium differentiation were temperature 15℃, humidity 80%, photoperiod less than 12 hours-short day; the best condition for corolla primordium differentiation were temperature 12℃, humidity 70 %,photoperiod less than 12 hours-short day; the best condition for stamen primordium differentiation were temperature 15 ℃, humidity 80 %, photoperiod less than 12 hours-short day;the best condition for carpel primordium differentiation were temperature 20℃, humidity 60%, photoperiod less than 12 hours-short day.
