Abstract: The effects of nitrogen fertilizer on the occurrence of Petiole Spot Disorder in Chinese cabbage were studied by nitrogen fertilizer application amount and application method. The results showed, in high amount nitrogen fertilizer application treatment (treatment 3), the occurrence of Petiole Spots Disorder is obviously serious than low amount nitrogen fertilizer application treatment (treatment 1 and 2). With the same total amount of nitrogen fertilizer application, the occurrence of Petiole Spots Disorder is more serious with the high amount in base-application treatment (treatment 2) than the low amount in base-application treatment (treatment 1). The results also showed, there are gene type differences on the occurrence of Petiole Spots Disorder in Chinese cabbage.
