【摘要】 根据鱼台县历年气候资料、水稻产量,结合水稻生长发育每个阶段对温度、水分、光照的具体要求进行分析对比,得出影响鱼台水稻产量波动的主导气象因子是移栽期的降水量及抽穗开花期的低温阴雨,次要因子是灌浆期的温度和日照。通过分析水稻产量与气象因子的关系,找出影响水稻生长的关键期,并提出在今后水稻生产中的相应对策。更多还原

【Abstract】 According to climate data and rice yield of Yutai in recent years,temperature,water and sunshine requirements at each stage of the rice growth and development were analyzed and compared,and found out the dominant meteorological factor affecting the rice yield of Yutai is the precipitation during the transplanting period and the wet weather during heading and flowering period;the secondary factor is temperature and sunshine at the grain-filling stage.Through analyzing the relationship between the rice yield and meteorological factors,the crucial period affecting rice growth were found out and the counter measure while growing rice in the future was advanced.更多还原
