【摘要】 调查结果表明,山东省日照市东港区土壤中N、P、K比例失调,土壤pH值过低,酸化较重,微量元素丰缺差异悬殊。通过分析养分变化和酸化原因,今后应该根据土壤养分状况、酸化状况,有针对性地开展测土配方施肥研究,以推进东港区农业向高产、优质、高效发展。更多还原

【Abstract】 The survey results showed that the contents of total N,total P and total K were unbalanced.The pH value was too low and the soil acidification was serious.The contents of the trace elements were different.Through the analysis of the nutrient’s change and the cause of soil acidification,soil testing and formulated fertilization should be researched to advance high-yield,high-quality,efficient development for agriculture in Donggang District according to the detailed soil.更多还原
