摘要: 在宁夏采用"四元二次通用回归旋转组合设计"布置试验,对影响大豆产量的密度、尿素、磷酸二铵、氯化钾四项因素进行了综合研究,建立了大豆产量回归目标性状与参试因素的函数模型,利用模型分析了参试因素对产量影响的效应。通过众多的品种筛选淘汰,确立了以理想株型,单位面积粒数多,百粒重高的黑农33号品种与此"数模"匹配的高产配套栽培新技术。

Abstract: Applicatian experiment of plant density, urea, ammonium Phosphate, potash muriate affecting output of soybean variety Heinonq 33 were comprehensively conducted with the quadric orthogonal rotation design. The mathematical model for relationships of soybean yield with the 4 experimental factors abovementioned was established at the same time, and the individual and reciprocal influence of the experimental factors on the target character were analyzed by utilization of the mode. Some standard cultural techniques were suggested and special measures which influence soybean variely Heinong 33 were quantitatively discussed as well.
