| Abstract: | The relationships between SPAD readings and the contents of chlorophyll and nitrogen in Chinese cabbage leaves and nitrogen applications were researched.The results showed that there was a significant correlation between SPAD readings and the contents of chlorophyll and nitrogen in Chinese cabbage leaves and N applications,chlorophyll content of Chinese cabbage leaves would be determined quickly using SPAD-502 chlorophyll meter,SPAD readings could be used to N nutritional diagnosis of plants. |
