摘要：

A three-part study was conducted to improve the measurement of strength in the High Volume Instrument (HVI) classification system for cotton by adjusting the measured strength for moisture content. First, a resistance-type moisture meter was used to develop the HVI strength-moisture relationship and formulate correction equations based on data from 275 cotton samples conditioned at five relative humidity levels. The first model validation was conducted at a U.S. Department of Agriculture, Agricultural Marketing Service (AMS) Office to verify the algorithm on cotton samples that were not used in the model development. The second model validation involved field-testing the approach in an AMS Classing Office to determine if moisture conditioning could be relaxed. The study showed that the resistance moisture meter system allowed HVI strength readings to be corrected with reasonable error on samples that had not been preconditioned to a standard relative humidity.
