| Abstract: | Objective] The quick and convenient testing method of Leymus chinensis leaf area was studied.Method] On the base of the analysis of the relationship between leaf area and the ratio of leaf length and width,the comparative study on them was conducted with a digital image method.Results] The regression analysis and error analysis result indicated that the K value,a correcting coefficient,in the calculation of leaf area was 0.655 5,which had higher accuracy in actual test.Conclusion] There was high consist... |
