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个构杞品种(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,构杞解除休眠的需冷量和萌芽展叶的需热量因品种不同而异。需冷量值品种间差异较小,介于480~720 h(≤7.2℃模型)或480~787 h(0~7.2℃模型)或553~829 C·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143~182 D℃(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。
Three different models for estimating cold demand (≤7.2 ℃, 0 ~ 7.2 ℃ and Utah model) and two different models for estimating calorie requirement (hourly growth rate and effective accumulated temperature model) ) Of the cold and heat required for determination, while the relationship between the two analysis. The results show that the structure of Qi to lift dormancy and the amount of heat needed to expand leaves vary with different varieties. The differences between the cold-tolerance varieties were small and ranged from 480 to 720 h (≤7.2 ℃ model) or 480 ~ 787 h (0 ~ 7.2 ℃ model) or 553 ~ 829 C · U (Utah model) Line) were higher than those in South China. The difference in calorific value was also small, ranging from 3696 to 4704GDH ℃ (hourly growth model) or 143 ~ 182 D ℃ (effective accumulated temperature model). No matter what kind of estimation model to estimate the demand and demand of Chinese wolfberry calories, Chinese wolfberry varieties (lines) no significant correlation between the cold and calorie needs.
