摘 要: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。Sulphur deficiency in soils of China was estimated and indicated by a map (Fig. 1). Based on estimation of input and output of soil sulphur and crop response to sulphur fertilizers, it was stated that sulphur deficiency would not occur in large areas of China in the near future. Under certain special conditions, however, paddy soils submerged under cold water, or some sandy soils might become sulphur deficient. The decreasing use of sulphur containing fertilizers, as a consequence of developing the chemical fertilizer industry, is predicted.
