摘　　要：在田间条件下,设置不施肥对照(T1)、单纯施用化肥对照(T2)、化肥+0.5 kg/m^(2)秸秆堆肥(T3)、化肥+1.0 kg/m^(2)秸秆堆肥(T4)和化肥+1.5 kg/m^(2)(T5)秸秆堆肥5个处理,研究了秸秆堆肥对华北落叶松苗木生长、养分吸收和根际土壤肥力的影响。结果表明,单纯施用化肥处理与不施肥处理相比提高了华北落叶松的株高、地径和总干重,添加秸秆堆肥的处理进一步提高了华北落叶松的株高、地径和总干重以及其各器官的氮、磷、钾含量和根际土壤的全氮、碱解氮、有效磷、速效钾、有机碳和有机质含量。综合而言,在华北落叶松移栽苗木培育过程中,建议秸秆堆肥的施用量为1.00 kg/m^(2)。Under field conditions,5 treatments were set up including non-fertilization control(T1),simple application of chemical fertilizer control(T2),chemical fertilizer+0.5 kg/m^(2)straw compost(T3),chemical fertilizer+1.0 kg/m^(2)straw compost(T4)and chemical fertilizer+1.5 kg/m^(2)straw compost(T5).The effects of straw compost on the growth,nutrient absorption and rhizosphere soil fertility of Larix principis-rupprechtii seedlings were studied.The results showed that the simple application of chemical fertilizers increased the plant height,ground diameter and total dry weight of Larix principis-rupprechtii compared to the non-fertilization treatment.The treatment of adding straw compost further increased the plant height,ground diameter and total dry weight of Larix principis-rupprechtii,as well as its nitrogen,phosphorus,potassium content in various organs and the total nitrogen,alkaline nitrogen,available phosphorus,available potassium,organic carbon and organic matter content in the rhizosphere soil.Overall,it was recommended to apply 1.00 kg/m^(2)of straw compost during the cultivation of transplanted Larix principis-rupprechtii seedlings.
