摘要: 通过研究不同土壤氮素供应对冬小麦拔节期叶绿素仪SPAD读数和植株硝酸盐浓度的影响, 以及两种方法在冬小麦拔节期与土壤Nmin、植株全氮和吸氮量的关系, 比较了SPAD叶绿素仪和植株硝酸盐测试两种氮素营养诊断方法的准确性。认为两种方法都可以比较好的反映冬小麦的氮素营养状况, 植株硝酸盐浓度与SPAD读数相比能更好的反映作物的氮素营养状况。

Abstract: The effects of different soil N supply on SPAD chlorophyll meter readings and plant sap nitrate concentration were studied for winter at shooting stage. By study the correlation between SPAD chlorophyll meter reading and sap nitrate concentration with soil Nmin, and total N content, the accuracy of the two plant N status diagnosis methods were studied. It is showed that the two methods could predict the winter wheat N status conectly, and the plant sap nitrate test is a better method than SPAD chlorophyll meter test. The SPAD chlorophyll meter could be used to as a plant N status diagrosis tool, and could be used in N fertilizer recommendation.

Key words: SPAD chlorophyll meter, Stem sap nitrate test, Nnutrient agatus, Winter wheat
