| 摘 要： | 采用田间小区试验和非线性回归分析的方法,对作物的密度与产量的经验模型进行模拟和比较。结果表明:二次曲线模型运算简洁、可操作性强,是模拟谷子密度与产量关系的最优模型。谷子种植密度对籽粒产量具有重要影响。谷子籽粒产量随着种植密度增加呈先升后降的趋势。

| Abstract: | The main density on crop yield empirical model,a few fitting models were simulated and compared by employing field plot experiment and nonlinear regression analysis. The results showed that the summer sowing foxtail millet planting density on yield had important influence. The trend of foxtail millet grain yield with planting density increase was first increased then decreased. Through the model simulation and comparison, quadratic curve model operation concise, the maneuverability was strong,was considered the optimal model that the foxtail millet density and yield relate. |
