摘    要:近年来,高浓度磷复肥的迅速发展带动整个磷肥产业蓬勃发展的同时,在一定程度上影响了低浓度磷肥的发展空间。传统的低浓度磷肥(过磷酸钙、钙镁磷肥)的产量从2000年的428万吨P2O5到2004年的468万吨P2O5基本稳定的情况下,在磷肥总产量中的比重从64.6%下降到46.0%。基于农户调查和统计数据,对我国低浓度磷肥的生产分布状况、使用状况、资源利用状况的分析表明,低浓度磷肥产量的徘徊不前与农业生产对中量元素需求增加的矛盾将拓展低浓度磷肥的市场空间;生产低浓度磷肥适用的磷矿品位与我国磷矿资源条件的吻合,使低浓度磷肥在未来有很大的发展空间。另外,通过核算低浓度磷肥的中微量元素价值来提高产品的性价比是促进低浓度磷肥产业健康发展的可能途径。总之,在现阶段磷肥产业的结构的调整、农民消费群体对低浓度磷肥的深入认识和低浓度磷肥企业生产技术水平与管理水平的提高,都将对低浓度磷肥的持续健康发展产生较大的影响。

关 键 词:低浓度磷肥    过磷酸钙    钙镁磷肥    农业使用

Abstract:In recent years,the rapid development of high analysis phosphorous fertilizer have influenced the developing of low analysis phosphorous fertilizer,although it have brought the flourishing development of phosphorous fertilizer industry.From 2000 to 2004,the low analysis phosphorous fertilizer leveled off with the outputs of 4,280,000—(4,680,000 t) P_2O_5,while the proportion in the total output of phosphorous fertilizer was dropped from 64.6% to 46.0%.The conditions of low analysis phosphorous fertilizer's manufacture,use and resources utilization were studied base on the inquisitional and statistical data.It shows that the inconsistency between the steady outputs of low analysis phosphorous fertilizer and the rapid demand of all kinds of nutrient for agricultural production can increase the market room of low analysis phosphorous fertilizer.It also indicates that the inconsistency between the phosphate demand of low analysis phosphorous fertilizer and the usability of phosphate rock can bring great development in future.In addition,improving the cost performance of the products through checking and calculating the trace element value in low analysis phosphorous fertilizer is possible ways to protect the healthy development of low analysis phosphorous fertilizer industry.In a word,the adjustment of the structure of the phosphorous fertilizer industry at the present stage,farmer's know with low analysis phosphorous fertilizer and the improving of enterprise's engineering and management level can make great influence on the healthy development.
Keywords:low analysis phosphorous fertilizer  single superphosphate  calucium-magnesium-phosphate  agricultural use
