测土配方施肥在西洋参种植中的应用研究

Study on the application of soil formula fertilization in the planting of American ginseng

为筛选出适合在东北地区西洋参种植过程中的最佳施肥方法,该试验采用测土配方施肥技术,通过两年的田间试验,分析了土壤中氮、磷、钾含量和西洋参的田间生长情况,通过去向回收模型计算后,得出西洋参在鲜根重、干根重方面都好于常规经验施肥,在出苗保苗及锈腐防效上与经验施肥效果相似,无明显差别,说明此模型具有实际操作意义,可以应用于田间实践。

To select suitable for American ginseng grown in the northeast area the best in the processof fertilization method, based on the soil testing and fertilizer technology through two years of field ex-periment, analyzes the content of nitrogen, phosphorus and potassium in the soil and the field of Ameri-can ginseng growth situation.
