影响大豆产量的因子研究

Study on the Factors Influnence the Yield of Soybean

为探索不同因子对大豆产量的影响，采用五元二次正交旋转组合设计研究了氮、磷、钾、钼、密度对大豆产量。试验结果表明各因子对产量的影响大小顺序是钾〉密度〉氮〉磷〉钼，产量大于210．79kg／667m。的最优栽培模式为：密度0．8429万～0．8561万株／667m^2，氮17．345-18．015kg／667m^2，磷33．14-34．610kg／667m^2，钾19．055-19．620kg／667m^2，钼肥1．099～1．173kg／667m^2。

In order to explore the effects of different factors on yield of soybean. With five quadratic orthogonal rotation combination design, a mathematical model of nitrogen, phosphorus, potassium, molybdenum, density on soybean yield. The results showed that the impact of each factor on yield were： K〉 density〉 N〉 P〉 Mo, production of soybean is greater than the optimum cultivation patterns 210.79kg / 667m^2 were： Density 0. 8429 - 0. 8561 million/667m^2 , nitrogen 17. 345 - 18. 015kg/ 667m^2 , phosphorus 33.14 - 34.610kg/667m^2 , potassium 19. 055 - 19. 620kg/667m^2 , molybdenum 1. 099 - 1. 173kg/ 667m^2.
