| 摘 要： | 试验于1987～1989年在本院教学实验场进行。采用二次回归正交旋转组合设计,对影响籽粒苋产量形成的密度,播期、氮、磷.钾的施用量5项关键性农艺措施进行了定量化的综合研究。初步确定了最佳农艺措施组合方案,并利用产量反应模型研究了各项农艺措施对产量形成的单独反应以及各项农艺措施间的互作效应。

| Abstract: | The experiment was carried out on the experimental farm in HunanAgricultural College during 1987 to 1989. Through quadratic regression orthogo-nal rotational combinatorial design we made a quantitative comprehensive stu-dy of the five critical agronomic measures of sowing density, sowing time,N,P,K application amount. During the years we selected the best synthetic de-sign of agronomic measures primarily, and studied both single reactions andinteractions of all agronomic measures that affect the yield of A. tricolar linnusing yield reaction model. |
