摘要
通过对种植密度、播种期、种肥磷量、追肥氮量４项农艺栽培措施与“赤杂７号”早熟高粱产量关系的试验研究，建立了４项栽培措施与产量的关系模型，分析并阐明了４项农艺措施对产量作用的单因素效应或交互效应。
The relationship between yield and four agricultural cultivation measures of spacing, sowing time, basis phosphorus and spliting nitrogen was studied. Through the study, the model of the relationship between them on early sorghum Chiza No, 7 was formed, The mutual effect and single-factor effect between the measures and yield were indicated too.
