阜新市春播关键期大风变化及其对粮食产量的影响
Variations of Strong Winds During the Critical Spring Sowing Period in Fuxin City and Their Impact on Grain Yield
摘要
Abstract
Using meteorological data of Fuxin from 1953 to 1986,including strong winds in the 2023 and the grain output of Fuxin from 1986 to 1986,the 2023 was analysed by various statistical methods,the conclusion is as follows:the annual variation of Gale Days in Fuxin and Fuxin Mongol Autonomous County shows a de-creasing trend,and the gale days in the past 20 years in the 21st century in the two counties are obviously less;Both counties have the most gale days in April,followed by May,and the oscillating cycles of gale days are basically the same,the first main cycle is about 65 years,the second main cycle is about 30 years,the third main cycle is about 13 years,and the most significant meteorological factor is the diurnal difference of air pressure,the second is relative humidity,and the third is average temperature There is a negative correlation between gale days and grain yield in the key period of spring sowing in Fuxin.The regression equation of gale days and grain yield is Y=23.514-0.523 x,and the coefficient,constant and equation of Gale are tested by 0.05.关键词
