摘　　要：以山地杨树人工林为对象,研究了不同覆盖量和覆盖材料对杨树叶片养分的影响。结果表明:覆盖提高了杨树叶片的养分含量,7.5kg/m^(2)处理的叶片养分含量最高,各元素含量因覆盖材料的不同而异。Effects of mulching weights and materials on dynamic of nutrient contents of poplar in leaves in southern upland area were investigated in this paper.The results showed that biological mulching enriched nutrient contents of poplar in leaves.Upmost nutrient contents in leaves were found in mulching of the 7.5kg/m^(2) treatment,and nutrient contents varied with different mulching materials.
