百喜草对土壤渗透率的影响

Studies on Effect of Bahia Grass on Soi Infiltration Rate

本实验测定了百喜草区、假俭草区及对照区的土壤渗透率。百喜草的初渗率、稳渗率最高，假俭草次之，对照区最小。并根据何登式渗透公式，建立了土壤渗透率推估式。

The capcities of soil infiltration in Bahia grass (Paspalum notatum),Eremochloa ophiurbides and contrast areas were tested.The initial infiltration rate and the final infiltration rate in the Bahia grass area was the highest,the lowest one was in the contrast area.The study provides the foundation for the establishment of the soil infiltration model according to Hortons infiltration equation.
