不同枸杞品种（系）需冷量及需热量的初步研究

用3种不同的需冷量估算模型（≤7．2℃、0—7．2℃和犹他模型）和2种不同的需热量估算模型（生长度小时和有效积温模型）分别对19个枸杞品种（系）的需冷量和需热量进行测定，同时分析两者的相互关系。结果表明，枸杞解除休眠的需冷量和萌芽展叶的臀热量因品种不同而异。需冷量值品种间差异较小，介于480—720h（≤7．2℃模型）或480—787h（0—7．2℃模型）或553—829C·U（犹他模型），且北方品种（系）的需冷量值普遍高于南方品种；需热量值品种间差异也较小，介于3696—4704GDH℃（生长度小时模型）或143—182D℃（有效积温模型）。无论以何种估算模型估算枸杞的需冷量和需热量，我国枸...

Summary:用3种不同的需冷量估算模型（≤7．2℃、0—7．2℃和犹他模型）和2种不同的需热量估算模型（生长度小时和有效积温模型）分别对19个枸杞品种（系）的需冷量和需热量进行测定，同时分析两者的相互关系。结果表明，枸杞解除休眠的需冷量和萌芽展叶的臀热量因品种不同而异。需冷量值品种间差异较小，介于480—720h（≤7．2℃模型）或480—787h（0—7．2℃模型）或553—829C·U（犹他模型），且北方品种（系）的需冷量值普遍高于南方品种；需热量值品种间差异也较小，介于3696—4704GDH℃（生长度小时模型）或143—182D℃（有效积温模型）。无论以何种估算模型估算枸杞的需冷量和需热量，我国枸杞品种（系）的需冷量和需热量之间无明显的相关性。
Bibliography:Three different models（ ≤7.2℃, 0 -7.2 ℃ and Utah Model）for estimating chilling requirements and two different models （ Growing Degree Hours and Effective Temperature Model）were used to estimate the heat requirements of wolfberry cultivars, the chilling and heat requirements of 19 wolfberry cultivars under protected culture were studied, and their correlations between chilling requirement and heat requirement were established. The result showed that the different chilling and heat requirements of tested cultivars were observed. Their chilling requirements had slight difference, ranging between 480 h and 720 h （≤ 7.2 ℃ Model ） or between 480 h and 787 h （0 - 7.2 ℃ Model） or between 553 C · U and 829 C · U （Utah Model）, the chilling requirement of the north cultivars was more than that of the southern euhivars. The heat requirements also had slight difference, ranging between3696 and 4704 growing degree hours（GDH） or between143 ℃ and 182 ℃ （ Effective Temperature Model）. No matter how to estimate the chilling or
