福建早稻产量结构要素的气象影响研究
Research of the Effect of Meteorological Condition on the Element of the Yield Composition of Early Rice in Fujian
【摘要】 通过对福建早稻多年田间观测数据与气象资料的相关和回归分析,研究气象条件对早稻产量结构要素的影响,结果表明穗结实粒数是造成早稻产量年际变化的主要因素,幼穗分化到乳熟期的光温水条件对早稻产量起着主要作用。
【Abstract】 By means of the correlation and regression analysis between the measure data of early rice in site and the meteorological data for many years in Fujian, we study the effect of meteorological condition on the element of the yield composition of early rice. The result reveals the quantity of grain is the major factor to dominating the amount of yield of early rice annually, and the meteorological condition such as sun light, temperature and precipitation during the period of the spike splits stage to the milk stage make an major impact on the yield of early rice.
