摘要
基于大球盖菇林下套种技术,以种植过大球盖菇的宜良花园林场杉木—华山松林下和富民县罗免基地核桃林下土壤为研究对象,选取相邻地区未种植大球盖菇土壤为对照,采用SPSS 21软件中独立样本t检验对其土壤理化性质进行检测分析。结果显示,林下种植过大球盖菇的土壤密度、总孔隙度均有增加,改善了土壤的通透性;大球盖菇能有效地增加土壤的有机质、水解性氮(N)、有效磷(P)和速效钾(K)的含量,提高土壤肥力,并能提高土壤pH值,中和酸性土壤。
Based on the intercropping technology of Stropharia rugosoannulata under-forest cultivation,the soils in Cunninghamia lanceolata-Pinus armandii forest of Huayuan Forest Farm in Yiliang County and in Juglans forest of Luomian base in Fumin County were studied with the control forest.The independent sample t test and analysis for physical and chemical properties of soil by SPSS 21 software showed that the soil density and total porosity in forests of Stropharia rugosoannulata under-forest cultivation increased,and the soil permeability was improved.The under-forest cultivation of Stropharia rugosoannulata effectively increased the content of organic matter,hydrolytic nitrogen(N),available phosphorus(P)and available potassium(K)in soil,improved soil fertility,increased soil pH value and neutralized acidic soil.
