摘要
为探寻合适的林药复合种植模式,在昆明市海口林场选择华山松+滇黄精、油橄榄+滇黄精、核桃+滇黄精3种不同林药复合种植模式,1.5年后对3种林药复合种植模式下的土壤有机质、氮、磷、钾含量进行对比分析。结果表明:华山松+滇黄精复合模式林地土壤肥力得到提高,其中土壤有机质、全氮、有效磷和全钾提高较为明显;油橄榄+滇黄精复合模式对林地土壤有效磷、速效钾含量的影响较大,其余指标差异不明显,土壤总体肥力变化也不明显;核桃+滇黄精复合模式林地土壤除速效钾和全钾含量提高外,其余指标含量均下降。林下种植滇黄精对土壤理化性质有影响,且不同林分复合种植模式下的影响差异明显,其中以华山松+滇黄精复合模式对土壤理化性质有明显的改善作用,适合推广。
In order to explore suitable forest medicine compound planting modes,three different forest medicine compound planting modes,namely Pinus armandii+Polygonatum kinganum,Olea europaea+Polygonatum kinganum,Juglans reiga+Polygonatum kinganum,were selected at Haikou Forest Farm in Kunming City to compare and analyze the soil organic matter,nitrogen,phosphorus,and potassium contents of the three forest medicine compound planting modes after 1.5 years.The results showed that the soil fertility of Pinus armandii+Polygonatum kinganum compound mode forest land was improved,with significant improvements in soil organic matter,total nitrogen,available phosphorus,and total potassium;the Olea europaea+Polygonatum kinganum compound mode had a significant impact on the content of available phosphorus and available potassium in forest soil,while the differences of other indicators were not significant,and the overall changes in soil fertility were also not significant;except for the increase in available potassium and total potassium contents,the contents of other indicators in the soil of Juglans reiga+Polygonatum kinganum compound mode decreased.Planting Polygonatum kinganum under the forest has an impact on soil physical and chemical properties,and the impact varies significantly under different forest compound planting modes.Among them,the Pinus armandii+Polygonatum kinganum compound mode has a significant improvement effect on soil physical and chemical properties,which is suitable for popularization.
