分析了南宁地区一年两收栽培模式下巨峰和夏黑葡萄连续两年的物候期与生长发育期的有效积温和光照时数之间的关系。结果表明,第一季光照时数较少,即阴雨天较多时,需要较高的有效积温才能使果实成熟,且从萌芽到果实成熟的时间会延长,而由于南宁地区下半年阴雨天气较少,影响巨峰和夏黑葡萄二季果果实成熟的主要气候因子是有效积温。此外,研究还发现,巨峰和夏黑一、二季果从萌芽到果实成熟的平均生长发育期均比北方短。
The relationship between the effective accumulated temperature and photoperiod of phenophase, growth and development of Kyoho and Xiamei Grapes under two year cultivation pattern in Nanning was analyzed. The results showed that the first season less light hours, that is, more rainy days, the need for a higher effective accumulated temperature in order to make the fruit mature, and the time from germination to fruit maturity will be extended, and the second half of the Nanning rainy weather less , The main climatic factors that affect Jufeng and summer black grape fruit ripening are effective accumulated temperature. In addition, the study also found that the average growth and development of Jufeng and summer black one and two seasonal fruit from germination to fruit ripening are shorter than the north.
