【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.更多还原
