摘要: 由于不同土类对硫吸附的强弱不同,决定了不同土壤田间施硫量的差异.在满足氮、磷、钾、铜、锰、锌等营养元素的基础上,以土壤有效硫临界值的2.5~3.0倍(35~42μg·mL-1)水平作为高产土壤需具备的硫含量,然后根据吸附曲线,求出不同土壤类型硫肥施用量.田间试验表明这一确定施硫量的方法是可行的,该方法比单纯用土壤速效硫含量确定的田间施硫量更合理。

Abstract: For the different absorption features, sulphur application quantity is different. On the basis of enough N, P, K, Cu, Mn and Zn content, using 2.5~3.0 times S deficient critical value as the demanding S, S application quantity of different soils was decided according to the absorption curve. They were testified by the field experiments. This method was more reasonable than that only using soil available S as the standard of fertilizing recommendation.

Key words: Sulphur, Absorption, S application quantity, Soil
