摘要: 对科尔沁沙地西南部种植时间为2000年、2004年及2007年的不同林龄黄柳灌丛0~60cm土壤9项指标进行测定。结果表明:3种林龄黄柳灌丛各土层土壤全磷、全钾含量均表现为10a生含量最高,7a生次之,14a生最低;土壤pH表现为随林龄增加而降低;3种黄柳灌丛0~60cm土层全氮、速效钾、土壤有机质、土壤pH表现为随林龄增加而降低;全磷、全钾、速效磷及水分表现为10a生最高,7a生次之,14a生最低;碱解氮表现为7a生>14a生>10a生;土壤有机质与全氮达到了0.87的高度正相关。

Abstract: Determination of 9 soil index in the soil layer(0~60cm)of Salix planted in 2000,2004 and 2007 was done in southwestern Horqin sandy land.The results showed that total P and K in each soil layer of the 3 Salix shrubs of 10 years old>7 years old>14 years old,the pH 7 years>10 years>14 years.7 years>10 years>14 years in soil layer(0~60cm)of the 3 Salix total N.available K,soil organic matter and pH.Total P,K available P and H2O is 10 years>7 years>14 years.Available N is 7 years>14 years> 10 years.Correlation analysis showed that there was a positive correlation between soil organic matter and total N that was 0.87.

Key words: Horqin sandy land, Salix, soil chemical properties
