摘要
通过对温室内10个月季品种在一年中各个时期的修剪,观测并记录了月季从萌芽至采收期时的生长发育时间、积温量、光照强度以及日照日总量等参数,得出月季生长发育时间和积温量成显著的正相关,而积温量与光照强度和光照时数成负相关,且不显著,进而推导出月季采收期周年积温预测模型方程,即y=355.62+6.89x。对月季各个采收期的积温量预测和花期预测预报,以及花期的适时调控具有重要的现实意义。
Based on 10 cultivars Rose pruning in different stage, the time of growth, accumulated temperature, light intensity and daily total of Rose from budding to cutting flower were measured and recorded. The result showed that there was a significant positive correlation between time of growth and accumulated temperature, there was a slightly negative correlation between accumulated temperature and light intensity, we deduced the equation that prediction model of accumulated temperature of Rose at harvest time, y = 355.62 ＋ 6.89x. The prediction of accumulated temperature and florescence at different harvest time, flowering time regulator have important significance.
