大豆是我国重要的油料作物之一,它在农业生产中占有重要的地位。干物质重量是大豆高产的物质基础。为了研究大豆高产栽培,许多单位曾从栽培生理角度进行过单因素的试验研究。但水分、肥料、密度等因素与大豆干物质重量之间的综合关系研究得不多。为此,我们在单因素试验研究基础上,于1980—1982年研究了水分、施氮肥、施磷肥、密度等四个栽培因素与大豆产量间的综合关系及其数学模型(《中国油料》,1983年第3期),同时也研究了这些栽培因素与大豆干物质重量间的综合关系及其数学模型。
Soybean is one of the important oil crops in our country and occupies an important position in agricultural production. Dry matter weight is the material basis for high-yield soybeans. In order to study high-yield cultivation of soybean, many units conducted a single-factor experimental study from the perspective of cultivation physiology. However, the comprehensive relationship between moisture, fertilizer, density and other factors and dry matter weight of soybean has not been much studied. Therefore, on the basis of single factor experiments, we studied the comprehensive relationship between the four cultivation factors such as moisture, nitrogen fertilizer, phosphate fertilizer and density and soybean yield and their mathematical models (“China Oilseed” 1983 No. 3), but also studied the cultivation of these factors and the dry weight of soybean between the comprehensive relationship and its mathematical model.
