Effects of nitrogen and sulphur [N3.75S0.35 (N 3.75 mmol/L, S 0.35mmol/L), N3.75S4.2(N 3.75 mmol/L, S 4.2mmol/L), N7.5S1.4(N 7.5 mmol/L, S 1.4mmol/L), N22.5S0.35(N 22.5 mmol/L, S 0.35mmol/L)] on the growth and quality of in bunching onion (Allium fistulosum L. var. caespeitosum Makino) were studied in hydroponics, in which the solution was Hoagland's. The results showed that the growth of bunching onion in N7.5S1.4 treatment was better than in other treatments. With nitrogen increasing, the growth of bunching onion enhanced at the same sulphur level, and the growth of bunching onion enhanced by sulphur increase at the same nitrogen level. Concentrations of chlorophyll a, b, total chlorophyll and carotenoid in N7.5S1.4 treatment were highest. With nitrogen and sulphur increasing, concentration of soluble protein and nitrate in bunching onion increased. While concentration of soluble sugar decreased with nitrogen increased.
