Abstract: The effect of botanical foliar fertilizers on the yield, quality and nutrient absorption of Zhangqiu green chinese onion was investigated by field experiment. Botanical foliar fertilizer 1 (FF1) was made of Burdock extracts and Burdock Oligosaccharide. Foliar fertilizer 2 (FF2) was made of Burdock extracts and Oligoehitosan. The results suggested that: Zhangqiu green chinese onion yield of FF1, FF2 and Tianda2116 (TD) were increased respectively by 10. 47%, 7.88% and 11.27% than customary fertilizer application(HF). Nitrate content of FF1, FF2 and TD were decreased by 10. 96%, 9. 47% and 15.07% respectively;Vc content of FF1 increased by 13.23% than that of HF;N recovery efficiency of FF1, FF2 and TD were increased by 2.31, 7. 11, 2. 75 percentage point respectively than that of HF;P2O5 recovery efficiency of FF2 and TD increased by 2.09 and 3.50 percentage point respectively than that of HF;K2O recovery efficiency of FF2 and TD increased by 9. 24 and 0.28 percentage point respectively than that of HF. All the results suggested that the Zhangqiu green chinese onion yield of FF1 was higher than that of FF2, the quality of FF1 was better than that of FF2, but the N, P2O5 and K2O recovery efficiency of FF2 were higher than that of FF1. So the botanical foliar fertilizer used for Zhangqiu green chinese onion should be made by Burdock extracts, Burdock Oligosaccharide and Oligoehitosan. It will not only increase the yield and quality of Zhangqiu green chinese onion, but also increase the N, P2O5 and K2O recovery efficiency.

Key words: Burdock Oligosaccharide, Oligoehitosan, Green chinese onion, Nitrate, Vc
