摘要:在内蒙古敖汉旗选择3种防护林,比较4个深度(0~10、10~20、20~40cm和40~60cm)的土壤有机质、碱解氮、速效磷和速效钾含量。结果表明,杨树×樟子松林的有机质含量最高,柠条和沙棘2种灌木林次之。杨树×樟子松林的碱解氮含量最高,沙棘林次之。杨树×樟子松林的速效磷含量最高,沙棘林次之。杨树×樟子松林的速效钾含量最高,柠条林和沙棘林次之。因此,杨树×樟子松林的土壤养分条件较好,沙棘林次之。这2种防护林可以作为科尔沁沙地的优化防护林类型。
Soil nutrient conditions were examined in different shelterbelts to give theoretical basis for planta- tion management in semi-arid area. Three types of shelterbelt (mixed forests of poplar and pin, Hippophae rharnnoides, and Caragana microphylla) were selected to compare soil nutritional indices, such as soil water content, soil organic matter, available nitrogen, phosphorus and potassium in four different soil depths, 0--10,10--20,20--40 and 40--60 cm in Aohan Banner of Inner Mongolia. The results indicated that soils of mixed shelterbelt of poplar and pine contained the highest contents of organic mater, available nitrogen, phosphorus, potassium, and moisture, followed by those of H. rhamnoides and C. microphylla.
