    目前葉麵積的測定方法有很多
，比如光電求積儀法、葉模法、透明方格板法、稱重法等。但在實際生產應用中，這些方法會破壞植株，影響植株的正常生長發育
，測量過程也比較繁瑣。為此

，托普雲農研製出了葉麵積測定儀，它能在不破壞植株的基礎上，快速準確地測定出葉麵積。
    葉麵積測定儀的操作也很方便，以獼猴桃果樹為例，葉麵積測量步驟如：首shou先xian將jiang獼mi猴hou桃tao果guo樹shu葉ye子zi的de葉ye麵mian與yu葉ye柄bing的de連lian接jie處chu放fang置zhi於yu儀yi器qi的de掃sao描miao處chu，然ran後hou按an住zhu手shou柄bing處chu紅hong色se的de按an鈕niu，隻zhi到dao聲sheng音yin響xiang起qi同tong時shi屏ping幕mu顯xian示shi正zheng在zai測ce量liang時shi
