资源简介:
玉米在成熟期的种植密度直接影响作物的生长条件、病虫害发生率以及最终产量。合理预测玉米在成熟期时种植密度,从而能够在分蘖期适时调整种植密度对于提高单位面积产量、优化资源使用及减少病虫害具有重要意义。该模型有效的解决了玉米生长状况与种植密度之间的预测关系。通过调查采集玉米在分蘖期的相关数据,并使用多元线性回归模型预测玉米种植密度,该模型的输入量依次为抗病评分、发病率(%)、叶片颜色指数(SPAD)、株高(cm)、病虫害类型、生育期(天)、分蘖数,多元线性回归算法通过分析这些输入量与玉米种植密度之间的线性关系,确定每个输入量相关的权重系数,使用深度学习框架构建模,模型通过最小二乘法等技术,根据输入的数据从而计算出玉米种植密度预测值。在模型训练过程中,算法会利用最终在成熟期测得的玉米种植密度实际值进行优化,调整上述的权重系数以最小化预测误差,因此上述每个权重系数在成熟期后,算法会根据实际值与预测值进行比较后会进行动态调整的。
Maize planting density at maturity directly affects crop growth conditions, pest and disease incidence, and final yield. Accurately predicting maize planting density at maturity and timely adjusting planting density during the tillering stage holds great significance for improving yield per unit area, optimizing resource utilization, and reducing pest and disease hazards.
This model effectively addresses the predictive relationship between maize growth status and planting density. Relevant data of maize during the tillering stage are collected and investigated, and a multiple linear regression model is used to predict maize planting density. The input variables of this model are, in order: disease resistance score, incidence rate (%), leaf color index (SPAD), plant height (cm), pest and disease type, growth period (days), and tiller number. The multiple linear regression algorithm analyzes the linear relationship between these input variables and maize planting density to determine the weight coefficients corresponding to each input variable. The model is constructed using a deep learning framework, and techniques such as the least squares method are applied to calculate the predicted value of maize planting density based on the input data.
During the model training process, the actual measured values of maize planting density at maturity are utilized for optimization, adjusting the aforementioned weight coefficients to minimize prediction error. Therefore, after the maturity stage, each weight coefficient will be dynamically adjusted based on the comparison between the actual values and predicted values.
