高粱在我省分布较广,具有广泛的适应性和较强的抗逆力。本文以豫中许昌等四县多年高粱产量和气象资料为材料,采用统计学中逐步回归的方法,用IBM—PC微型机进行运算,筛选出与产量有关的气象因子,并求出各因子的最适与临界指标,被选入方程的有八、九月份降水过多,七、九月份均温过高,都引起明显减产,其它月份都是适宜的。在土壤足墒时,较多的日照对高豫的生长发育是有利的。 Sorghum is widely distributed in our province, with a wide range of adaptability and strong resilience. In this paper, Xuchang, Henan and other counties for many years sorghum yield and meteorological data for the material, the use of statistical step by step regression method using IBM-PC microcomputer operation, screening out the yield-related meteorological factors, and find out the various factors The most suitable and critical indicators were selected into the equation in August and September too much precipitation, July and September were too high, have caused a significant cut, other months are appropriate. When the soil is full of moisture, more sunshine is beneficial to the growth and development of Yuya.
