Abstract

Abstract The study aimed to determine the optimal pulverisation index of soil for disk harrow by modelling. A mathematical model was developed using a Design-Expert software and response surface methodology. Experiments were carried out in silty loamy soil with three different levels of soil moisture content of 9.25%, 17.56%, and 22.32%, operating depths of 10 cm, 15 cm, and 20 cm, and operating speeds of 3.17, 4.85, and 5.47 km·h-1. The quadratic model proposed by the Design-Expert software was statistically significant (P <0.01), with a strong correlation relationship (R2 = 0.989) between actual and predicted soil pulverisation index values. The adequacy precision achieved at 41.84 showed the models‘ ability to navigate the design space. However, statistical analysis, using the t-test and P-value, showed the actual and predicted values have no significant differences in the pulverisation index of soil. The optimal soil pulverisation index (8.61 mm) was achieved with a desirability of 1.00, at a soil moisture content of 14.43%, an operating depth of 11.64 cm, and a forward speed of 5.30 km·h-1. Model validation confirmed acceptability (R2 = 0.974) and a 99% accuracy in predicting the soil pulverisation index.

在不同操作条件下，利用响应面方法对圆盘耙的土壤粉碎指数进行优化和建模

摘要该研究旨在通过建模确定圆盘耙的最佳土壤粉碎指数。使用 Design-Expert 软件和响应面方法建立了一个数学模型。实验在淤泥质壤土中进行，土壤含水量分别为 9.25%、17.56% 和 22.32%，作业深度分别为 10 厘米、15 厘米和 20 厘米，作业速度分别为 3.17、4.85 和 5.47 km-h-1。Design-Expert 软件提出的二次方模型具有显著的统计学意义（P <0.01），实际和预测土壤粉碎指数值之间具有很强的相关关系（R2 = 0.989）。达到 41.84 的适当精度表明模型有能力驾驭设计空间。然而，使用 t 检验和 P 值进行的统计分析显示，土壤粉碎指数的实际值和预测值没有显著差异。在土壤含水量为 14.43%、工作深度为 11.64 厘米、前进速度为 5.30 公里/小时-1 的条件下，达到了最佳土壤粉碎指数（8.61 毫米），可取性为 1.00。模型验证确认了预测土壤粉碎指数的可接受性（R2 = 0.974）和 99% 的准确性。
