摘    要:运用土壤动力学原理建立了灌溉水入渗的数学模型,并进行了实际灌水的试验验证,试验结果表明所建模型的模拟结果与试验结果吻合较好。应用模型模拟分析发现:适量增加沟宽或回土量可以减小入渗时间,缩短播种机排水口至排种口距离。

关 键 词:施水播种 灌溉水 入渗规律 数学模型 土壤动力学 沟宽 回土量 播种机

Abstract:A mathematical model for water penetration during watering sowing was developed in this paper on the principle of the soil dynamics, and field experiments were carried out. We found by this research that increasing the width of furrow and the amount of recovered soil could decrease the time of penetration and the distance from the water exit to the seed exit. The results from the model well coincided with those from the experiments, and all the results from this paper could be used as reference for designing and improving a watering sowing machine.
Keywords:Watering sowing   Irrigation water   Infiltration   Mathematical model
