Abstract: In order to prove up effect of sulfur on rice growth and sulfur absorption character of rice, water pot experiment was carried through. The results showed that lack sulfur suffocated rice growth obviously, put off procreation and resulted in badness of tassel and seed, the amount of root was little and root was slightness. The more sulfur applied, the higher output of rice increased. 1000 kernel weight and seed rate increased no more as soon as sulfur was applied beyond 0.180 mmol/L , which indicated that rice JinYou82 can grew in gear when sulfur content in culture solution ≥0.180 mmol/L. Rice was no seed when no sulfur was supplied. With sulfur was supplied, sulfur content in stem and leaf of rice and root increased, difference of which was significant. N, P and K contents in plant and root decreased after harvest. Sulfur content in grain increased with sulfur was supplied, which increased no more with 0.18mmol/L sulfur was supplied. N, P and K contents in grain have trend for increasing too, which was different to that in stem and leaf.
