大豆在农业生产中占有重要的地位。为了探讨大豆高产栽培措施,曾进行过如水分、肥料、密度、品种等单因素试验,以探讨对大豆产量的影响。但是,大豆产量是受多种因素综合的影响。所以,只研究单因素的作用不能反映出大豆产量与各因素之间的综合关系。为此,我们在单因素试验研究的基础上,于1980～1982年研究水分、N肥、P肥和密度等四个主要栽培措施与大豆产量间的综合关系及其数学模型,为大豆高产栽培提供科学依据。
Soybean occupies an important position in agricultural production. In order to explore high-yield soybean cultivation measures, such as moisture, fertilizer, density, variety and other single factor experiments to explore the impact on soybean yield. However, soybean production is affected by a combination of factors. Therefore, the study of single-factor effects does not reflect the overall relationship between soybean yield and various factors. Therefore, on the basis of single factor experiments, we studied the comprehensive relationship and mathematical models of four main cultivation measures of water, N fertilizer, P fertilizer and density and soybean yield from 1980 to 1982, Provide a scientific basis.
