选择江苏省连云港市花果山优势树种麻栎树为研究对象,采集其位于不同海拔位置的树木叶片,测量鲜重及经不同程度阴干处于不同水分状态下叶片的水分指数(W I)和含水率(FMC),在叶片水平上,研究水分指数与含水率之间的关系。研究表明,水分指数对麻栎叶片含水率的变化敏感,二者之间统计关系明显;叶片含水率可以通过水分指数进行曲线拟合,拟合曲线为y=19.022x2-32.707x+14.064,其稳定性较好。
The dominant species of Quercus acutissima collected from Huaguoshan of Lianyungang City of Jiangsu Province were selected as the research object to collect their leaves at different altitudes and to measure the fresh weight and moisture content (WI) and moisture content of the leaves under different degrees of dryness under different water conditions (FMC). At the leaf level, the relationship between moisture index and moisture content was studied. The results showed that the moisture index was sensitive to the change of water cut in leaves of Quercus acutissima, and the relationship between the two indexes was obvious. The leaf water content could be curve fitted by water index, the fitting curve was y = 19.022x2-32.707x + 14.064 Stability is better.
