| 摘 要： | 通过田间开顶式小区熏气试验,研究了SO2急性伤害对水稻叶绿素含量、叶液pH值、叶片含硫量和冠层光谱反射率及其相关性的影响,为遥感监测SO2污染环境下水稻长势提供基础研究.结果表明,随SO2 熏气浓度的增大,叶绿素含量呈减少趋势,叶片含硫量呈增加趋势.叶液pH值相应地降低,光谱反射率曲线在绿光和红光波段、蓝光和绿光波段之间的吸收谷有变平的趋势.选取冠层光谱叶绿素反射峰(550 nm±10 nm反射率)和近红外波段770 nm±10nm反射率(反映叶片结构)与叶片含硫量、叶绿素含量和叶液pH值进行的相关分析表明,(550±10)nm(770±10)nm冠层光谱反射率与叶片含硫量呈负相关,与叶液pH值、叶绿素总量均呈正相关.

| Abstract: | Field experiment was carried out with a split plot design with rice variety named Lindao 10. Rice samples were exposed to sulfur dioxide at different concentrations inside fumigation chamber. After measuring visible and near infrared radiance of the canopies of rice, leaves of rice canopy were sampled to analyze sap pH, chlorophyll concentration and sulfur content of rice leaves. Chlorophyll content and sap pH of leaves reduced and sulfur content of leaves increased with the increased SO2 fumigation concent... |
