摘要

在挪威东南部的Apelsvoll研究中心，使用便携式叶绿素仪(Minolta SPAD‐502)在两个肥料试验中评估冬小麦(Triticum aestivum L.)的氮素状况。最后一个完全发育叶片的中点是冬小麦植株叶绿素测量的最佳位置。这一结论是在研究了植物不同位置的土壤-植物分析发育(SPAD)读数与叶片氮浓度、籽粒产量和籽粒蛋白质含量之间的关系后得出的。还强调了从实用的角度寻找方便的测量位置。Zadoks生育期(GS) 49的叶绿素测量值与各参数之间的关系较GS 31的好。

Use of a hand‐held chlorophyll meter in winter wheat: Evaluation of different measuring positions on the leaves

A portable chlorophyll meter (Minolta SPAD‐502) was used to assess the nitrogen status of winter wheat (Triticum aestivum L.) in two fertilizer trials at Apelsvoll Research Centre, located in south‐east Norway. The midpoint of the last fully developed leaf was found to be the best position on the winter wheat plant on which to take chlorophyll meter readings. This conclusion was reached after examination of the relationships between soil‐plant analyses development (SPAD) readings taken at different positions on the plant and leaf nitrogen concentration, grain yield and grain protein content. Emphasis was also laid on finding a measuring position that was convenient from a practical point of view. The relationships between chlorophyll meter readings and the parameters investigated were better at Zadoks growth stage (GS) 49 than earlier in the season at GS 31.
