根据膜孔畦灌大田灌水试验实测资料，研究了膜上水流推进规律，并对膜孔入渗采用Ｋｏｓｔｉａｋｏｖ入渗模型，提出利用膜孔畦灌田面水流推进和观测断面水深资料推求充分供水条件下点源入渗参数的新方法。实例计算表明，该法简单易行，并可消除土壤空间变异性对入渗参数的影响。该研究成果为膜孔灌理论与技术研究奠定了基础。 According to the experimental data of field irrigation experiment with membrane perfusion, the law of water flow in membrane was studied, and the Kostiakov infiltration model was used for the infiltration of membrane pores. It was put forward that the use of film hole 畦 irrigation field water flow to promote and observe the water depth of the section deduced the point source A new method of seepage parameters. The example calculation shows that the method is simple and easy to operate and can eliminate the influence of soil spatial variability on infiltration parameters. The research results laid the foundation for membrane pore irrigation theory and technology research.
