[Method] The special plant nutritional element （SPNE） was sprayed on the flowering Chinese cabbage plants after the beginning of harvesting. The effects of SPNE on the yield traits and biochemical quality traits of flowering Chinese cabbage were investigated in the un-conventional using period. [Results] The results showed the flowering stalk of flow-ering Chinese cabbage developed earlier and grew fasterly for the SPNE treatment;the diameter, length and weight of flowering stalk of SPNE-treated flowering Chi-nese cabbage were al higher than that of control. The SPNE treatment could not only increase yield, but also bring better biochemical quality. The protein, vitamin C and calcium contents, especial y the chlorophyl and sugar contents in the SPNE-treated flowering Chinese cabbage were al higher than that of control, making the SPNE-treated flowering Chinese cabbage taste better. [Conclusion] lt was indicated although sprayed after the beginning of harvesting, the SPNE had a certain effect on the flowering Chinese cabbage.展开更多
