1、硅钙镁磷钾肥在海南甘蔗上的施用效果研究摘要为了探讨硅钙镁磷钾肥在甘蔗上的施用效果，通过采用田间小区试验，研究了硅钙镁磷钾肥不同用量对甘蔗产量、蔗糖含量和土壤养分含量的影响。结果表明，施用硅钙镁磷钾肥较习惯施肥能够有效提高甘蔗产量，较习惯施肥增产1.8%〜9.8%，施用量为1500kg/hm2时产量最高，且随着施用量的增加呈增大趋势，施用量达到1875kg/hm2后，产景有所下降。施用硅钙镁磷钾肥能有效提高甘蔗蔗糖含量。随硅钙镁磷钾肥施用量增加，硅钙镁磷钾肥能提高土壤存效磷、速效钾和pH值，改良酸性土壤。综合试验结果

2、，硅钙镁磷钾肥用量以1500kg/hm2在甘鹿上的应用效果最佳。本文采集自网络，本站发布的论文均是优质论文，供学习和研究使用，文中立场与本网站无关，版权和著作权归原作者所有，如有不愿意被转载的情况，请通知我们删除匕转载的信息，如果需要分享，请保留本段说明。关键词硅钙镁磷钾肥；甘蔗；产量；蔗糖含量；土壤养分；海南地区中图分类号S156.2；S566.1；S147.5文献标识码A文章编号1007-5739(2017)08-0064-02ApplicationEffectsofSiliconPhosphorusPotas
