摘  要：
阐述世界硫肥的需求状况:到2012年世界农业缺硫量预计每年将达1 100万t,而亚洲和美洲将成为全球最严重的缺硫地区。环境污染控制、集约化农业生产以及低硫高浓度肥料的使用,加剧了全球范围内土壤缺硫状况。缺硫日益成为农业可持续发展和提高肥料利用率的限制因素之一,但也刺激农用硫肥的需求,为肥料工业开发新技术和新产品、开拓市场提供了契机。有3种硫肥,分别是:(1)硫酸盐基;(2)硫磺基;(3)液态硫基,其中硫酸盐基占绝大部分,其具有较好的理化特性,可直接、均衡为作物提供多种养分。本文介绍含硫肥料的种类、各种肥料的性能及目前世界上开发多种新型含硫肥料产品来适应和满足不同作物、土壤的需要。

摘  要：
The world sulfur fertilizer deficit is projected at close to 11 million tons per year by 2 012,with the Asia and the Americas as the most sulfur deficient regions in the world.Pollution controls,intensified cropping,and the absence of sulfur from high-analysis fertilizers are combining to produce a growing worldwide deficiency in soil sulfur;Sulfur deficiency is increasingly becoming one of the limiting factors to further sustainable increases in agricultural production and fertilizer use efficiency,and also is stimulating growth in farmers' demand for sulfur containing fertilizers,which is becoming a greater potential market for fertilizer industry to develop innovative technologies and products for exploring this market potential.Most sulfur-containing fertilizer materials can generally be divided into three groups:(1) Fertilizer containing sulfate;(2) Fertilizer containing sulfur,and(3) Liquid sulfur fertilizers.Sulfate-containing fertilizers provide the most of the fertilizer sulfur applied to soils,with good chemical and physical properties, and providing multinutrients with balanced ratios for plant nutrition for direct application purposes.Various sulfate-containing fertilizers are introduced from their properties to meet the demand based on specific crop and soil needs.
