摘要
A non-destructive way of measuring the state of a crop by means of image processing is presented. Three models which describe the relationship between the relative soil coverage by the crop canopy and dry weight are discussed. The accuracy of the method and of the models is determined from the two experiments in lettuce growth. It is shown that the best model can estimate the dry weight from the relative soil coverage with an accuracy of about 5%. It is also shown for lettuce that there is a linear relation between the leaf area and the dry weight of the plant.
