新型肥料的最新开发进展及应用

Newest development progress and application of new-style fertilizer

现代农业正在促使化肥品种结构发生变革,产生质的飞跃,近年来各种新型肥料不断问世。新型肥料的主要作用是能够直接或间接地为作物提供必需的营养成分,调节土壤酸碱度,改良土壤结构,改善土壤理化性质和生物学性质,调节或改善作物的生长机制,改善肥料品质和性质及提高肥料的利用率。21世纪以后,中国新型肥料研发和推广使用正快速发展,肥料结构不断优化,新型肥料更是异军突起。介绍了近期中国最新创制的活化磷肥、有机钾肥、氨酸螯合肥、含肽氮肥、硫磺加强型肥料、富过磷酸钙磷肥、生物有机肥、高分子聚合物增效肥料等8种新型肥料的开发进展和应用概况。

Leading role of new fertilizer is that it could provide the essential nutrient content for crops directly or indi- rectly, adjust soil pH, modify the soil composition,improve soil physics and chemistry nature and the biology nature, adjust or improve the growth mechanism of crops, improve fertilizer quality and its nature, enhance the use ratio of fertilizer. Mter entering the 21st century ,research and development and the promotion use of new fertilizer was developing fast in China,the fertilizer structure optimized unceasingly and the new fertilizer is sudden appearance. Development progress and application survey of 8 new fertilizers were introduced briefly that were activation phosphate fertilizer,organic potassium fertilizer,am- monia sour chela hefei,peptide - nitrogenous included fertilizer, sulfur - strengthened fertilizer, calcium - superphosphate - phosphate - rich fertilizer, biological organic fertilizer, high polymer efficiency fertilizer and so on.
