摘要
以河南主要的粮食作物作为研究对象,采用试验对比的方法,对使用两种型号叶面积仪和手工方格纸方法测得的叶面积数据进行比较分析,并以方格纸法测量的叶面积数据为参考,对两种型号叶面积仪的测量精确度和准确度进行了比较。结果表明:采用不同方法测量的叶面积数据的差异随着作物植株叶面积的增加而增大;采用GStar-Ⅲ型叶面积仪测量的叶面积数据重复性更好,测定结果更为稳定,测量精确度和准确度更高。
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
