印度硫肥研究进展

硫作为植物营养继氮磷钾后第四位重要元素，近年来受到国际植物营养界的高度关注，印度自８０年代以来对硫进行了广泛系统的研究，本文综述了印度在硫肥研究方面取得的进展，包括土壤各种形态硫的含量、影响因素与硫肥反应的相关性，不同硫肥品种的肥效对比及后效，不同作物对硫肥的反应及土壤植株体系硫的循环平衡等，对我们当前深入开展平衡施肥的试验示范有一定的参考意义。

Advances in the Study of Sulphurous Fertilizer in India

Sulphur is the fourth most important nutirent for plant growth after nitrogen, phosphate, and potassium. In recent years, sulphur is paid great attention by plant nutrient scientists around the world. Research on sulphur as a plant nutrient in India has progressed considerably over the past two decades. This paper updates earlier reprots on sulphur study including sulphur status of soils, sulphur crop uptake and removal, crop reponse to sulphur, comparative efficiency of sulphur sources, balance sheet of sulphur in plant-soil system. It has certain significance for instructing balanced fertilization and sulphur research in China.
