Comparative Analysis of Leaf Area Measurement Test Data
Abstract：The main food crops in Henan as the study object, adopting test contrast method, using two types of leaf area meter and hand graph paper method measured leaf area data were analyzed. And graph paper method to measure the leaf area data as a reference, the measurement precision and accuracy for two types of leaf area meter were compared. The results showed that： the differences of leaf area data were increased with the crop plants leaf area increasing using different methods; using GStar - Ⅲ type leaf area meter, the leaf area measured data had better repeatability, more stability, higher measurement accuracy and precision
