果园土壤入渗参数与畦灌田面综合糙率的确定
|
摘要
对果园畦灌土壤入渗参数和田面糙率系数的准确测定,有助于提高畦灌的灌水效果。文中在山西省夹马口灌区果园,选择四种土壤表面形态进行了入渗试验,确定了土壤入渗参数,根据试验结果,将灌区土壤分为强入渗、较强入渗、中等入渗和弱入渗四种入渗类型。利用模拟畦灌水流运动零惯量模型,采用反求参数的方法,获得四种土壤入渗类型畦灌田面综合糙率系数,为类似地区进行畦灌设计和管理提供重要的参考依据。
Accurate determination of soil infiltration parameters and field roughness coefficient of border irrigation in orchard was helpful to improve the irrigation effect of border irrigation. In this paper,four types of soil surface morphology were selected to infiltrate the orchards in Jiamakou irrigation area of Shanxi Province. According to the test results,the soil in the irrigated area was divided into four types:intension infiltration,strong infiltration, medium infiltration and weak infiltration. The comprehensive roughness coefficient of four types of soil infiltration types was obtained by using the model of simulated zero inertia of bed irrigation water movement and the method of reverse parameter calculation. It provided an important reference for the design and management of border irrigation in similar areas.
