摘要
利用不同估算模型分别对上海地区4个设施葡萄主栽品种的需冷量及需热量进行测定。结果表明:4个测试品种的需冷量值分别介于575—684 h(0—7.2℃模型)、738—895 h(≤7.2℃模型)和738—865 CU(犹他模型);‘巨玫瑰'需冷量最低,‘巨峰'最高;需热量值介于9 113—10 722 GDH(生长度小时模型);‘夏黑'需热量最低,‘醉金香'最高;4个葡萄品种的需冷量与需热量之间呈正相关关系。
The chilling and heat requirements of 4 leading grape varieties of protected culture in Shanghai area were calculated by different estimation models.The results showed that the chilling requirements of the 4 va-rieties were 575—684 h（estimated by the 0—7.2 ℃ model）,738—895 h（by the≤7.2 ℃ model）and 738—865 CU（by the Utah Model）;The chilling requirement of ‘Jumeigui’variety was the lowest and that of ‘Kyo-ho’was the highest;Their heat requirements were 9 113—10 722 GDH（estimated by the growing degree-hour model）;The heat requirement of ‘Summer Black’was the lowest and that of ‘Zuijinxiang’was the highest;There was a positive correlation between the chilling and heat requirements of the 4 varieties.
