Abstract

The dense canopy of rice causes attenuation of droplet dispersion during pesticide application. The canopy-opening device can increase droplet deposition in the middle and lower canopy of rice by causing disturbance to the rice canopy. However, the conditions for use of the canopy-opening device are difficult to determine. Rice morphological structure parameters and material parameters were measured to study the movement mechanism of the rice stems under the action of the canopy-opening device, and the canopy-opening process was then simulated using the explicit dynamic method. The simulation scene of the rice canopy-opening process considered the combination of three different heights and three different driving velocities of the canopy-opening device. The movement mechanism of the rice stems under the operation of the canopy-opening device was investigated, and the entire movement process was separated into two stages: contact and oscillation. The simulation results and high-speed photography experimental results show a strong correlation, with a correlation coefficient of 0.733. The simulation results indicate that when the canopy-opening device is closer to the ground and the driving velocity is higher, the disturbance to the rice stem during the contact stage is stronger. However, for the oscillation stage, there exists a critical value for both the height and driving velocity of the canopy-opening device. During the oscillation stage, there is a critical value for both the height and driving velocity of the canopy-opening device. The numerical-based explicit dynamics approach was employed in this work to investigate the rice canopy motion mechanism, and this study has a definite reference value for the investigation of complicated motion mechanisms in the field crop production process.

摘要

水稻密集的冠层会在农药施用过程中导致液滴分散的衰减。冠层开启装置可通过对水稻冠层造成扰动，增加液滴在水稻冠层中下部的沉积。然而，冠层开启装置的使用条件难以确定。测量了水稻形态结构参数和材料参数，以研究冠层开启装置作用下水稻茎秆的运动机制，然后采用显式动力学方法模拟冠层开启过程。水稻冠层开启过程的模拟场景考虑了冠层开启装置的三种不同高度和三种不同驱动速度的组合。研究了冠层开启装置运行下水稻茎秆的运动机制，并将整个运动过程分为接触和振荡两个阶段。模拟结果与高速摄影实验结果具有很强的相关性，相关系数为0.733。模拟结果表明，当冠层开启装置离地面较近且驱动速度较高时，接触阶段对水稻茎秆的扰动更强。然而，对于振荡阶段，冠层开启装置的高度和驱动速度都存在一个临界值。本文采用基于数值的显式动力学方法研究水稻冠层运动机制，该研究对大田作物生产过程中复杂运动机制的研究具有一定的参考价值。
