摘　　要：为了找出油菜的叶绿素(SPAD值)与其全氮含量的关系,利用叶绿素仪(SPAD)对田间油菜氮含量进行测试,并将已知SPAD值的油菜叶通过凯氏定氮法进行测定,将这两种方法得到的结果进行拟合,建立了SPAD值和全氮含量在油菜中的数学关系模型,结果表明相关系数达0.863,为油菜在生长期间全氮含量的快速测定提供了一种新的方法.In order to fined the relationship between the SPAD value and the nitrogen content of oilseed rapes, a Minolta SPAD-502 Meter was used for on farm measurement of the N content, and then the Kjeldahl method has been used for measuring the nitrogen content of these oilseed rapes. The results of these two methods have been fitted, as a result, the correlation coefficient is 0.863, a new method for quickly measuring the nitrogen content of oilseed rapes is offered.
