玉米叶片是玉米进行光合作用和蒸腾作用的主要器官。生产中,单位面积内有了适当的叶面积数量后,才能获得较高的产量。为了迅速准确地测定玉米的叶面积,我们对几种测定方法进行了比较。 1.求积仪法测得的叶面积比较准确,但工效低,一次只能测出300平方厘米以内的面积,只宜在测量样品少、叶面积小且要求精确度高的情况下使用。
Corn leaves are the main organs of photosynthesis and transpiration of corn. Production, the unit area with the appropriate number of leaf area, in order to obtain higher yields. In order to quickly and accurately determine the leaf area of corn, we compared several assay methods. 1. The product of the plot of the leaf area measured more accurate, but the work efficiency is low, only one area can be measured within 300 square centimeters, should only be measured in the sample less, the leaf area is small and the requirements of the use of high precision.
