Abstract
The effects of sulfur 95(S 95), elemental sulfur and superphosphate treatment and three levels of application rate of sulfur 95 (S,15,30,60 kg/hm2) on rape were studied in field experiments from 1997 to 1999. The results show that seed yield increase significantly with the application of sulfur fertilizer. The increase rate is 17.3%～42.8%(20.0%～42.8% for S 95,17.3%～37.9% for elemental sulfur and 20.4%～33.7% for superphosphate). The response in yield to S 95 is better than those of both elemental sulfur and superphosphate treatment.When the yield of rapeseed is high, the response to S 95 is better than those of both elemental sulfur and superphosphate treatment. Rapeseed yield increase significantly in three levels of application rate of S 95(S,15,30,60 kg/hm2); the straw and the root system increases 19.9%～66.8%,but it is insignificant.The total S contents in seed increases significantly and the N/S ratio in seed decreases with the application of sulfur fertilizers. The change ranges of them are related to the applying rate of sulfur fertilizers. No effect on total fat and total protein in rapeseed is shown with the application of sulfur fertilizer.
