在果树的试验研究中,也和其他农作物一样,常把叶面积作为重要的生理指标。在生育期间,考察叶面积动态变化规律,或不同条件下叶面积变化的对比,可以作为采取相应措施的依据。为了能夠较正确地测定出接近于实际的叶面积,现将各种测定方法及我们应用和比较的结果扼要叙述如下,供同志们参考。 In the experimental study of fruit trees, the leaf area is often used as an important physiological indicator like other crops. During the growth period, the dynamic changes of leaf area, or the contrast of leaf area under different conditions can be used as the basis for the corresponding measures. In order to be able to more accurately determine the leaf area close to the actual, now a variety of measurement methods and our application and comparison of the results briefly described below, for comrades reference.
