水稻生育期大的可分为两期:前期营养生长期和后期生殖生长期。从富阳地区农业气候角度看,营养生长期和生殖生长前期的气候条件比较稳定,我们对几个主要气候因子进行普查也证实了这一点。但由于后期的气候年际变化较大,以及晚稻生理对气候因子的反应比较敏感,因此气候因素直接造成了晚稻产量较大的波动。本文主要列晚稻抽穗扬花期和灌浆期气候因子进行分析,并建立富阳县晚稻产量的天气预报模式。 Rice growth period can be divided into two phases: early vegetative growth and late reproductive growth. From the perspective of agricultural climate in Fuyang, climatic conditions in the vegetative and pre-reproductive stages are relatively stable. We also confirm this by census of several major climatic factors. However, due to the large changes of climate in later stage and the sensitivity of late rice physiology to climatic factors, climatic factors directly cause large fluctuations of late rice yield. In this paper, the climatic factors of heading and flowering and filling stage of late rice were analyzed, and the weather forecasting pattern of late rice yield in Fuyang County was established.
