摘要
以Ca (NO3 ) 2 和NaCl按 5∶1的比例均匀混合设计 0 % ,0 1 % ,0 2 % ,0 3% ,0 5 % ,0 7%的盐浓度 6个处理 ,模拟宁夏不同日光温室的土壤含盐量 ,以番茄为试验对象 ,研究了不同浓度盐份对番茄苗期叶绿素含量 ,光合作用 ,荧光参数的影响。结果表明 ,在 0～ 0 5 %盐份处理对叶绿素含量有促进作用 ,在 0 1 %盐份处理对光合作用和光能转换率有刺激作用 ,但随着盐份浓度的加大 ,叶绿素含量降低 ,光合作用下降 ,光能转换率降低 。
Modeling characteristics of re-formed salted soil in protected cultivation by adding mixed salt of calcium nitrate and sodium chloride(5∶1) at 0%,0 1%,0 3%,0 5%,0 7% six management in dry earth The author research the photosynthesis and parameter of fluorescence of tomato in a pot experiment The chlorophyll of leaf of young plant was increased significantly at 0～0 5% but decreased above 0 5% photosynthesis and transform efficiency of light energy ware stimulated at 0 1% but alone with enhancement of mixed salt,growth of plant of tomato was inhibited significantly chlorophyll,photosynthesis and the transform efficiency of light energy was reduced
