本文根据四川安宁河流域玉米、大豆间(混)作制中,玉米、大豆不同结构形式引起的遮光程度,模拟四种光照强度的大豆遮光试验,分析了不同光照强度下大豆产量及产量构成因素间的相关性,确定产量因素对产量的直接和间接贡献,并采用BASIC语言程序,建立多元线性回归模式,提出不同结构形式的玉米、大豆间(混)作制中大豆的栽培主攻方向。
In this paper, according to the degree of shading caused by the different structures of maize and soybean in the system of corn and soybean (mixed) in Anning River Basin of Sichuan, the light-shading experiments of four kinds of light intensity were simulated to analyze the effects of different light intensities on the yield and yield component of soybean The direct and indirect contribution of yield factors to yield was determined. The BASIC language program was used to establish the multiple linear regression model. The main direction of soybean cultivation was put forward in different structure forms of corn and soybean.
