| 摘 要： | 通过对保护地栽培的施肥状况、土壤养分含量、pH值和土壤含盐量进行调查和分析,结果表明,保护地施肥过量,养分在土壤中大量积累,土壤次生盐渍化问题比较突出,造成土壤pH值降低,土壤电导率、含盐量增高,已影响到作物的正常生长。结合实际情况提出了相应的防治对策。 |
| 关 键 词： | 保护地 土壤盐渍化 施肥状况 养分分析 防治对策 |

| Abstract: | The fertilizer application status,nutrient content,pH value and salt content of protected soil in Shenxian county were investigated and analyzed.The results showed that the excessive application of fertilizer,a great amount of nutrient accumulation and serious soil salinization led to the decrease of pH value,electrical conductivity and salt content in protected soil.All these have been affecting the normal growth of crop.So some countermeasures were put forward. |
| Keywords: | Protected field Soil salinization Fertilization application Nutrient analysis Control countermeasures |
