| 摘 要： | 通过分层取样比较不同栽培年限苜蓿地土壤主要养分及在土体的垂直分布特征，分析了不同栽培年限苜蓿地土壤质量的变化．结果表明，苜蓿种植时间的长短对土壤主要养分分布影响程度不同，总体表现是苜蓿种植时间越长，对土壤主要养分分布影响越大．不同种植年限苜蓿地有机质、碱解氮、速效磷、速效钾含量随苜蓿栽培年限的增长而增加，随土层深度的增加而降低pH随苜蓿栽培年限的增长而略有降低，随土层深度增加而略有增加，但差异都不显著． |
| 关 键 词： | 紫花苜蓿 土壤 栽培年限 垂直分布 |

| Abstract: | Through the quite different planter ageing alfalfa soil nutrient, the change of alfalfa soil quality was analyzed,and the soil vertical distribution character was analyed . the result showed： the time for alfalfa - planting have different effect on the soil nutrient distribution, and the alfalfa - planting time is longer, its influence on soil nutrients is bigger. The content of organic matter available nitrogen .available Phosphorus, available Potassium in different alfalfa- planting time soil was increase with the increase of plant time , and decrease with the increase of soil depth . ph was decrease with the increase of alfalfa- planting age, and increase with the increase of the soil depth, but the differences is not remarkable. |
| Keywords: | Alfalfa Soil Planting-age Vertical distribution |
