| 摘要: |
| 研究了盆栽甜菜中三种改良剂不同组合下对盐渍土壤电导率、pH、速效钾和有效磷的影响。结果表明：不同处理的土壤电导率、pH、速效钾和有效磷表现出明显的规律性变化,土壤电导率、速效钾和有效磷随时间变化降低；土壤pH值随时间变化增大。其中,硫酸钙和硫酸铵的改良剂组合对降低土壤电导率作用较好,而改良剂组合中添加腐殖质对改善土壤酸碱度的作用较大。 |

| Abstract: |
| The effects of three different combinations of potted beet on the conductivity, pH, available potassium and available phosphorus of saline soil were studied. The results showed that the soil conductivity, pH, available potassium and available phosphorus in different treatments showed obvious regular changes, the soil electrical conductivity, available potassium and available phosphorus decreased with time, and the soil pH value increased with time. Among them, the modifier combination of calcium sulfate and ammonium sulfate has a better effect on reducing soil electrical conductivity, and the addition of humus to the modifier combination has a greater effect on improving soil pH. |
