Optical method is a important method for soil moisture moisture measurement.Until now
theadaptability of the method to field soil is lack.In this paper
based on the variation data of field soilphysical and chemical characterstics
by analysing the variation of dielectric constant
refractive in-dex
the influnency of the soil bulk density and chemical composition
texture and temperature foroptical measurement method are struied;It was concluded that while soil bulk density and texturehave a rather effect upon optical mesaurement method
it is difficult to use the optical mesaurementmethod to determine soil moisture in the fields.
