摘　　要：为了明确优良品种的高产栽培技术,实现良种良法配套应用推广,更好地发挥优良品种的增产潜力,以‘成胡14’为材料,研究密度、肥料水平对蚕豆农艺性状和产量的影响。结果表明,密度和肥料对大部分农艺性状和产量均表现极显著影响,且农艺性状的密度效应大于肥料效应,产量的肥料效应大于密度效应。在5个密度梯度和4个肥料梯度中,以15.0万株/hm2和375kg/hm2时‘成胡14’的各农艺性状和产量均表现较好。主成分分析结果表明,第一和第四主成分偏重不利于产量的提高,第三主成分对产量影响较小。在合理的栽培技术调控下‘,成胡14’可实现突出相应农艺性状和高产的协调。In order to find the high yield cultivation technology of the fine variety and to make the best use of potential variety, we used ＇Chenghu14＇ to study the effect of density and fertilizer levels on agronomic traits and yield of faba bean. The results showed that, density and fertilizer were greatly significant effects on most agronomic traits and yield. Meanwhile, density effect of agronomic traits was higher than fertilizer effect, and fertilizer effect of yield was higher than density effect. In five density levels and four fertilizer levels, as 150000 plants/hm2 and 375 kg/hm2 in ＇Chenghul4＇ showed better agronomic traits and yield. Principle component analysis results showed that, the first and the fourth main component stresses were not conducive to improving yield, and the third main component was less effect on yield. On the reasonable cultivation techniques, ＇Chenghul4＇ can be realized the corresponding coordinate of highlight some agronomic traits and yield.
