Abstract:

Soil fertility of artificial alfalfa grassland at seven different growing years was comprehensively analyzed to evaluate the effect of growing years on the soil quality using the grey correlation model and cluster analysis in the saline alkali area of northern Shanxi province in 2013. The results showed that different growing years had different effects on soil quality. Compared with farmland, alfalfa grassland with 2,3,6,10,13 growing years could improve soil quality and ten year's growing showed the best soil quality.

Key words: Alfalfa, Growing years, Grey correlation model, Cluster analysis, Soil quality

摘要：

以大同盆地盐碱区为典型样区，选择0，1，2，3，6，10，13年等不同种植年限人工紫花苜蓿（Medicago sativa）草地为研究对象，选取了11个指标，采用灰色关联度和聚类分析法评价人工苜蓿草地土壤质量的差异并划分优劣，确定最优种植或利用年限。研究表明：不同种植年限人工苜蓿草地对土壤质量有很大影响，与对照（农地）相比，恢复年限为2，3，6，10，13年紫花苜蓿草地均可提高土壤质量，其中种植10年苜蓿草地土壤质量最好。
