摘要: 在试验确定春季切花月季萌芽日温度指标和月季从萌芽至切花采收所需积温值的基础上,利用历史气象资料,分析研究了海宁切花月季萌芽至达到780℃.d和980℃.d积温采收期的时间分布特征,结果表明:由于月季切花采收期的年际迟早差别,会造成切花月季生产效益的较大差异。通过建立海宁春季切花月季采收期的两种预测模型,为相应农艺措施的采取提供依据。

Abstract: Temperature requirement in different stages of rose growth was crucial for precisely predicting the harvest time of cut rose. The daily average temperature of the budding day of cut rose and the accumulated temperature from budding to cutting flower were investigated as two major aspects of the temperature requirement. The results showed that the accumulated temperature from budding to cutting flower was 780 for low accumulated temperature rose and 980 for high accumulated temperature rose in Haining. Two models for predicting the harvest time of cut rose in Haining were built up based on the analysis of temporal characteristics of reaching the required accumulated temperature each year to guide the rose production.
