河北中部设施果树需冷量研究

Chilling Requirement of Flat Peach,Apricot and Plum in Solar Greenhouse in the Middle Region of Hebei Province

[目的]探讨河北中部设施果树蟠桃（Prunus persicalL.var.compressaBean）、杏（Prunus armeniacaL.）和李（Prunus salicina）的需冷量。[方法]利用07.2℃模式和犹它模式,结合试验,分析了保定市山前平原设施果树早露蟠桃、凯特和金太阳杏、大石早生李的需冷量。[结果]07.2℃模式在当地的适用性较好。早露蟠桃和凯特杏的需冷量为536h,金太阳杏和大石早生李的需冷量为507h。[结论]当地设施果树扣棚日期为12月下旬。

[Objective] The aim was to determine the chilling requirement of Prunus persical L.var.compressa Bean,Prunus armeniaca L.and Prunus salicina in solar greenhouse in Baoding City of Hebei Province.[Method] Two models,the 0-7.2 °C model and Utah model,were used to determine chilling requirement of Prunus persical L.var.compressa Bean cv.Zaolu,Prunus armeniaca L.cv.Katy,Prunus armeniaca L.cv.＇Jintaiyang＇,and Prunus salicina ＇Oishiwase＇ in solar greenhouse in Baoding City.[Result] The 0-7.2 °C model was suitable for Baoding.The chilling requirements of Prunus persical L.var.compressa Bean and Prunus armeniala L.were 536 h,and those of Prunus armeniaca L.cv.＇Jintaiyang＇and Prunus salicina ＇Oishiwase＇ were 507 h.[Conclusion] The period for solar green house in Baoding is the last 10 d of December.
