摘要:

目的 研究不同品种甜樱桃需冷量,对比相同品种甜樱桃不同地区需冷量差异。 方法 2021—2022年应用犹他模型、7.2℃模型和0~7.2℃模型对辽宁省葫芦岛市地区栽培的佳红、红灯、明珠、美国大红、砂蜜豆和美早6个品种甜樱桃以及江西省抚州地区栽培的砂蜜豆、明珠、佳红和美早4个品种甜樱桃进行需冷量估算。 结果 葫芦岛地区供试的甜樱桃品种,犹他模型所估算需冷量范围介于469~564.5 C.U之间,0~7.2℃模型所估算需冷量范围介于334~442 h之间,7.2℃模型所估算需冷量范围介于710~1218 h之间;抚州地区供试的甜樱桃品种,犹他模型所估算需冷量范围介于261.5~525 C.U之间,0~7.2℃模型所估算需冷量范围介于98~301 h之间,7.2℃模型所估算需冷量范围介于105~328 h之间。 结论 两地区同品种甜樱桃需冷量存在较大的差异,犹他模型估算结果差值最小,初步判断较为适宜用于不同地区甜樱桃需冷量对比研究。

Abstract:

Objective The Chilling Requirement (CR) of different varieties of sweet cherries were studied, and the differences in CR of the same varieties of sweet cherries in different regions were compared. Methods From 2021 to 2022, the Utah model, the 7.2°C model and the 0-7.2°C model were applied to the six varieties of sweet cherries cultivated in Huludao City, Liaoning Province, namely Jiahong, Hongdeng, Mingzhu, American Red, Sand Honey Bean and Meizao, as well as Jiangxi The CR of four varieties of sweet cherries cultivated in the Fuzhou region, namely Sand Honey Bean, Mingzhu, Jiahong and Meizao, were estimated. Results For the sweet cherry varieties tested in the Huludao area, the estimated CR of the Utah model ranged from 469 to 564.5 C.U. The estimated CR of the 0-7.2 °C model ranged from 334 to 442 h. The estimated CR range is between 710 and 1218 h; for the sweet cherry varieties tested in Fuzhou, the estimated CR range of the Utah model is between 261.5 and 525 C.U. The estimated CR of the 0-7.2 °C model The estimated CR ranged from 98 to 301 h, and the estimated CR of the 7.2 °C model ranged from 105 to 328 h. For the sweet cherry varieties tested in the Huludao area, the estimated CR of the Utah model ranged from 469 to 564.5 C.U. The estimated CR of the 0-7.2 °C model ranged from 334 to 442 h. The estimated CR range is between 710 and 1218 h; for the sweet cherry varieties tested in Fuzhou, the estimated CR range of the Utah model is between 261.5 and 525 C.U. The estimated CR of the 0-7.2 °C model The estimated CR ranged from 98 to 301 h, and the estimated cooling capacity of the 7.2 °C model ranged from 105 to 328 h. Conclusion There is a big difference in the CR of the same variety of sweet cherries in the two regions. The Utah model estimated the difference is the smallest, and the preliminary judgment is more suitable for the comparative study of the CR of sweet cherries in different regions.
