本文介绍中国南方土壤缺硫情况。根据土壤硫的收、支和硫肥对作物的效应估计,中国南方在最近的将来不会出现大面积土壤缺硫。在某些特殊情况下,冷浸田或砂土可能缺硫。预言随着化肥工业发展,将减少含硫肥料的使用。
This article describes the soil sulfur deficiency in southern China. Based on the estimation of the effects of sulfur in soils, crops and sulfur fertilizers on crops, large areas of soil sulfur deficiency will not occur in southern China in the near future. In some special cases, cold-dip fields or sand may be deficient in sulfur. It is predicted that as the fertilizer industry develops, the use of sulfur-containing fertilizers will be reduced.
