气候是重要的农业自然资源。广东的气候为农业生产提供了丰富的光、热、水资源,但因季风气候显著,灾害天气较为频繁,限制了农业的高产稳产。七十年代以来,由于气候变动,我省有1/2的年份,出现春暖迟,秋凉早,晚秋台风多,使早晚稻生产,特别是给晚稻生产带来严重的影响。因此,加强科学研究,掌握气候规律,对夺取晚稻稳产高产具有重要的意义。一、晚稻增、减产的天气气候特点解放以来,我省晚稻生产的发展速度不快,大致经历这几个阶段:1950～1958年连年增产;1959～1961年连年减产;1962～1969年,各年产量有增有减,但仍保持上升趋势;
Climate is an important agricultural natural resource. Guangdong’s climate provides abundant light, heat and water resources for agricultural production. However, due to the significant monsoon climate and frequent disaster disasters, the high and stable agricultural output has been limited. Since the 1970s, due to the climate change, there are 1/2 years in our province, with late spring, early autumn and late autumn with more typhoons, which have a serious impact on the production of morning and evening rice, especially for the production of late rice. Therefore, to strengthen scientific research and grasp the laws of climate is of great significance in seizing stable and high-yielding late rice. I. Characteristics of Weather and Climate of Late Rice Increased and Output Reduced Since the liberation, the development of late rice in our province has experienced a period of unpleasant development. It generally went through several stages: the annual production increased from 1950 to 1958; the annual output was reduced from 1959 to 1961; from 1962 to 1969, Production increased or decreased, but still maintained an upward trend;
