摘要
需冷量是甜樱桃引种栽培、设施栽培和预测气候变化的关键依据。本文通过总结≤7.2℃模型、0~7.2℃模型、Utah模型和动力学模型在我国甜樱桃需冷量估算上的应用研究,得出≤7.2℃模型因数值不稳定逐渐被替代,0~7.2℃模型因便于操作、数值年际间差异小、较为稳定而在我国广泛应用;Utah模型和动力学模型虽然考虑到高温和低温对低温累积的影响,但由于计算复杂并没有得到广泛应用。同时,基于中国知网文献数据对不同模型、不同地理位置、不同品种的需冷量进行比较分析,阐述需冷量的影响因素,并对今后研究方向进行展望,以期为甜樱桃适地适栽及品种选育提供理论依据。
Chilling requirement is the key basis for sweet cherry introduction, protected cultivation and climate change prediction. By summarizing the application of ≤7.2℃ model, 0~7.2℃ model, Utah model and Kinetic model in the estimation of chilling requirement for sweet cherry in China, it was concluded that ≤7.2℃ model was gradually replaced due to numerical instability, while 0~7.2℃ model was widely used in China because of easy operation, small interannual difference and stability. Although Utah model and Kinetic model considered the influence of high temperature and low temperature on chilling requirement, they were not widely used because of their complex calculation. Based on the literature data of CNKI, the chilling requirement obtained by different models of different varieties from different geographical locations were analyzed and compared, and the influencing factors and research prospects were expounded to provide theoretical bases for cultivation at suitable time and place and variety breeding of sweet cherry.
