摘要
本研究以牡丰7号为试验材料,研究栽培密度、施肥量及有效含量3方面因素对产量的影响,每个因素设置5个水平,采用三元二次正交旋转组合设计方法。结果表明,对产量影响因子效应的大小依次为有效含量>栽培密度>施肥量,适当增加施肥量、减小栽培密度将获得牡丰7号大豆的高产。
The effects of the planting density, fertilization arate and effective concentration on the yield of Mufeng No. 7, a high-yielding cuhivar were investigated with the method of three-factor quadratic orthogonal rotation combination design. The result showed that the order magnitude affecting soybean yield was effective concentration, planting density, and then fertilization rate; It was proposed that proper increase in fertilization rate with effective concentration and reduced planting density could obtain high yield of cv. Mufeng No. 7
