通tong過guo使shi用yong葉ye綠lv素su計ji來lai進jin行xing對dui海hai島dao棉mian的de不bu同tong生sheng長chang時shi期qi的de葉ye綠lv素su含han量liang進jin行xing測ce定ding並bing分fen析xi，發fa現xian海hai島dao棉mian在zai不bu同tong的de生sheng長chang時shi期qi其qi變bian化hua規gui律lv均jun是shi不bu一yi樣yang的de
，從cong海hai島dao棉mian的de苗miao期qi到dao開kai花hua期qi，它ta的de葉ye綠lv素su含han量liang變bian化hua不bu大da
，幾ji乎hu是shi維wei持chi不bu變bian的de，但dan是shi隨sui著zhe海hai島dao棉mian的de繼ji續xu生sheng長chang，從cong開kai花hua期qi到dao花hua鈴ling期qi葉ye綠lv素su含han量liang在zai慢man慢man的de增zeng加jia，直zhi到dao花hua鈴ling期qi葉ye綠lv素su含han量liang到dao達da最zui高gao值zhi
，接jie著zhe葉ye綠lv素su含han量liang開kai始shi下xia降jiang
，海hai島dao棉mian中zhong的de葉ye綠lv素su含han量liang開kai始shi慢man慢man的de被bei分fen解jie，直zhi到dao最zui終zhong收shou獲huo。葉ye綠lv素su的de這zhe一yi變bian化hua，也ye可ke以yi反fan映ying到dao植zhi物wu氮dan素su含han量liang和he需xu求qiu的de一yi種zhong變bian化hua。此ci時shi我wo們men可ke以yi不bu定ding期qi的de測ce定ding植zhi物wu的de氮dan素su含han量liang
