论述了不同作物对硫素的需求特性，缺硫反应、硫肥肥效以及相同作物不同品种间的需硫量差异。综合评述了作物缺硫的土壤与植株诊断的方法与研究动态，探讨了作物硫素营养诊断中所面临的问题及解决途径，为深入开展作物缺硫诊断的研究等提出了新的思路。
The demand characteristics of sulfur, the sulfur deficiency reaction, the efficiency of sulfur fertilizer and the sulfur requirement of different varieties of the same crop were discussed. This paper reviewed the methods and research trends of soil and plant diagnosis of sulfur deficiency in crops and discussed the problems and solutions in crop sulfur nutrition diagnosis and put forward new ideas for further research on the diagnosis of crop sulfur deficiency.
