三穗县耕地质量现状及改良措施

Current Situation and Improvement Measures of Cultivated Land Quality in Sansui County

为摸清三穗县耕地质量现状,以便指导施肥和提出改良措施,对三穗县耕地质量状况进行研究。结果表明:三穗县耕地土壤总体呈酸性,氮、磷丰富,钾相对缺少,有机质含量高,钙、镁、硫含量丰富,缺硅和硼。针对耕地质量现状,提出增施有机肥和钾肥,控制氮肥、适施磷肥、补施硅、硼肥,施用酸性土壤改良剂,改良土壤结构,增加土壤通透性,提高土壤有效氧分含量,增加土壤肥力。

In order to find out the current situation of the quality of cultivated land in Sansui County, to guide the fertilization and put forward the improvement measures, the quality of cultivated land in Sansui county was studied. The results showed that the soil in Sansui county was acidic, rich in nitrogen and phosphorus, potassium was relatively short, organic matter content was high, calcium, magnesium and sulfur were rich in content, lacking of silicon and boron. In view of the present situation of cultivated land quality, the paper brings forward that the enrichment organic fertilizer and potash fertilizer, nitrogen control, appropriate P fertilizer, supplying potassium silicon, boron fertilizer, application of acidic soil amendments, improve soil structure, increase soil permeability, improve soil effective oxygen content, increase soil fertility.
