云南省新平县稻田土壤耕层养分状况
Southwest China Journal of Agricultural Sciences(2015)
Abstract
为了解稻区土壤养分状况,并根据养分丰缺情况进行合理科学的施肥,最终实现水稻优质高产,对云南省新平县稻田土壤pH值、有机质、碱解氮、有效磷、速效钾、有效硫、有效镁、有效硼、有效锰、有效锌进行养分分析.结果表明,53.80%的土壤偏酸,23.40%的土壤有机质偏低,24.20%的土壤碱解氮缺乏,39.20%的土壤缺磷,65.80%的土壤缺钾,22.60%的土壤缺硫,7.87%的土壤缺镁,85.27%的土壤缺硼,14.04%的土壤缺锰,37.67%的土壤缺锌.水稻生产中应注意增施有机肥、钾肥,以培肥地力,补施硼肥,保持土壤养分平衡.
