摘　　要：随着氮磷钾肥用量的增大、复种指数及作物产量的提高,土壤硫的供给越来越成为提高农作物产量和改善其品质的限制因素。本文比较系统地介绍了目前国内外在土壤硫的形态、转化及其有效性方面的研究进展。尤其对土壤硫的生物转化做了比较详尽的评述。Sulfur is becoming a limited factor of crop yield increase and crop product quali- ty improvement due to large input of N,P and K fertilizers,cropping index and crop yield increase.This paper summarizes the advance in the research of soil S transformation and available capacity.The importance of biological factors in soil S is also discussed in this paper.
