施肥对红枣叶片SPAD值与比叶重影响的研究
Effect of Feitilization Amout on SPAD Value and Specific Leaf Weight of Ziziphus Jujube Leaves
摘要
Abstract
[Objective] The experiments were conducted to study SPAD values of Ziziphus jujube(Z. J) leaves, and explore the effect of SPAD value changes with fertilization with the purpose of providing basis for promoting the utilization of nutrition of the fruit trees of Xinjiang. [ Method ] Trace study were worked on special position of jujube trees to determine leaves SPAD values under different amount of fertilizer. [ Result] The result showed that the relationship of SPAD values and fertilization rate was positive correlation, but the SPAD values had downtrend when nitrogen rate attained certain level. It was that SPAD values were significantly correlated with specific leaf weight (SLW) when the leaves were young. [Conclusion] It is very necessary to build SPAD value standard in different dynamics under different nutrients provided in order to use chlorophyll apparatus better and have a better diagnostic effect.关键词
