| 摘 要： | 为了实现番茄无损测试诊断的目标,利用叶绿素仪SPAD-502测定了番茄不同生育期成叶、新叶的SPAD读数值。结果表明:番茄无论新叶还是成叶全氮含量、叶绿素含量都与SPAD测定值有很好的相关性;随着施肥量的增加,番茄植株体内的叶绿素含量、全氮含量都在增加,番茄SPAD读数在逐渐的增大,番茄的维生素C含量呈上升趋势,在600kg/hm~2时,果实维生素C含量达到最大值,当施氮量为900kg/hm~2时,番茄体内的可溶性固形物达到了最大值。SPAD能够对番茄的营养状况作出诊断。

| Abstract: | The number of leaves developed in different stages and SPAD readings of new leaves were tested with chlorophyll meter SPAD-502 in order to conduct non-destructive diagnosis.The results showed that the content of total nitrogen and chlorophyll in both new and matured tomato leaves correlated with the SPAD reading positively.The content of total nitrogen and chlorophyll in tomato plants increased with more input of fertilizer and so as the SPAD value.The content of VC also gradually increased and reached maximum value with the nitrogen content of 600 kg/hm~2. The solid content of tomato reached highest level with the nitrogen content of 900 kg/hm~2.Therefore,SPAD could make diagnosis on tomato nutritious status. |
