| 摘 要： | 为给测土配方施肥提供技术参数,在半干旱区淤黑垆土上进行该项试验研究,其结果表明,在667m2基施农家肥2000kg基础上,单施尿素20kg、碳酸氢铵60kg的水分生产率最高,其次是过磷酸钙、磷酸二铵、有机肥和硫酸钾,其水分生产效率差异不大。今后测土施肥推广应采用氮、磷、钾配合使用,可有效提高水分生产率,667m2节本增收15.06元。 |

| Abstract: | For Formula Fertilization by soil testing to provide technical parameters,in semi-arid region of silt Heilu soil on the pilot study,the results show that,in the mu base apply farmhouse fertilizer based on 2000 kg,20 kg of urea,ammonium bicarbonate 60 kg water productivity is highest,followed by calcium superphosphate,ammonium phosphate,organic fertilizer and potassium sulfate,its water production efficiency difference.The future soil testing Fertilization extension should be used in nitrogen,phosphorus,potassium used in conjunction,can effectively improve water productivity,acres of abridged edition is added receive 15.06 yuan. |
