摘　要：

对萌芽时期差异比较大的葡萄品种进行萌芽进度调查, 统计了萌芽进度不同阶段相应的空气有效积温和土壤有效积温, 分析了空气有效积温和土壤有效积温与葡萄萌芽进度之间的相关性。结果表明, 空气有效积温、土壤有效积温与葡萄萌芽进度呈显著正相关, 空气有效积温和土壤有效积温共同参与葡萄萌芽。萌芽早的葡萄品种对空气有效积温的依赖性比较大, 对土壤有效积温的依赖性比较小; 萌芽晚的葡萄品种萌芽进度受土壤有效积温的影响更大。葡萄萌芽期间对土壤有效积温的需求量要高于对空气有效积温的需求。土壤有效积温与空气有效积温之间存在线性关系。

Abstract:

Effective accumulated temperature in air and soil together with bud burst process in two grapevine cultivars of different germination date were investigated. Relationship between two kinds of effective accumulated temperature and budburst process were analyzed. The results showed that, both soil and air effective accumulated temperature had an positive relationship with budburst process. Both soil and air effective accumulated temperature particapated the process of bud burst. The early burst cultivar relied more on air effective accumulated temperature during bud burst process, on the contrast, the late burst cultivar had a more close relationship with soil effective accumulated temperature. Both cultivars need more soil effective accumulated temperature than the air effective accumulated temperature. A significant linear relationship was conducted between soil and air effective accumulated temperature.
