| Abstract: | The experiment with different sulfur fertilizers (gypsum, sulfur, potassium magnesium sulphateSPM) application to rice was carried out in the soil of sulfur deficiency. The results showed that application of sulfur, calcium and magnesium to rice all have significance for yield increase, and sulfur is the best one.Among the application of three kinds of sulfur fertilizers, the application of gypsum has the biggest yield increase and the application of sulfur has the best benefit. This paper also discussed the effect of sulfur on rice growth, nutrition conditions and quality. |
