摘　　要：针对各苗圃的地力下降和营养不均衡状况,进行了测土施肥试验。以兴安落叶松容器苗作为样材,采用正交设计方法,分别对新播容器苗和芽移容器苗进行测土施肥。结果表明:在该立地条件下,新播苗肥料的最佳配比为1∶14,最佳施肥量为磷酸二铵45.5g/m2;芽移苗肥料的最佳配比为1∶23,最佳施肥量为尿素6.5g/m2、磷酸二铵39.0g/m2,使苗木当年达到出圃标准。An experiment of soil testing and fertilizer recommendation was conducted to newly planted and differentiated shoot transplanted container seedlings of Larix gmelini using the orthogonal design aiming at the degradation and unbalanced nutrient in the nursery soil. Result shows that the optimum proportioning of fertilizers for newly planted seedlings was 1 ： 14, and the optimal applying amount of fertilizer was 45.5 g per square meter of diammonium phosphate without urea. While the suitable proportioning of fertilizers for shoot transplanted seedlings was 1 ： 23, and the optimal applying amount of fertilizer was 6.5 g per square meter of urea and 39.0 g per square meter of diammonium phosphate. The seedlings could attain the criterion for the normal seedlings.
