摘要：

摘要：叶绿素含量是反映作物光合能力的一个重要指标，与作物产量形成有着极其密切的关系。为了通过施肥定量调控叶绿素含量，本研究通过长期定位施肥来揭示氮肥－有机肥配合施用对冬小麦－夏玉米叶片叶绿素含量的影响规律。结果表明：随着氮肥或有机肥施用量的增加，无论是冬小麦还是夏玉米，叶片叶绿素含量（SPAD值）均会增大，与氮肥和有机肥的施用量的函数关系分别表达为：

Abstract:

Abstract: Chlorophyll content is the impotent index to photosynthetic activity of corps, and there is a very close relationship with yield. In order to control chlorophyll content by fertilization, in this paper ,the rule that the effect of N-Fertilizer and marure cooperation to chlorophyll content of winter wheat and summer corn was discovered by long-term fertilization. It was showed the chlorophyll content of winter wheat and summer corn would increase with N-Fertilizer and marure increasing, and the functions were expressed by equation:
