摘要
为给灵芝(Ganoderma lucidum)生态栽培模式推广提供科学依据,以种植2年黄灵芝(Ganoderma luteum)的大叶栎(Quercus griffithii)、红锥(Castanopsis hystrix)和火力楠(Michelia macclurei)人工林为研究对象,探究短期黄灵芝栽培对林分土壤理化性质的影响。结果表明,种植黄灵芝的大叶栎、红锥和火力楠人工林土壤容重、质量含水率、毛管孔隙度、非毛管孔隙度、总孔隙度、通气度、毛管持水量、最大持水量和田间持水量均有不同程度变化。种植黄灵芝的大叶栎人工林土壤非毛管孔隙度显著高于未种植黄灵芝的大叶栎人工林。种植黄灵芝的红锥人工林土壤毛管孔隙度和总孔隙度均显著高于未种植黄灵芝的红锥人工林,种植黄灵芝的红锥人工林土壤非毛管孔隙度显著低于未种植黄灵芝的红锥人工林。种植黄灵芝的大叶栎、红锥和火力楠人工林土壤pH值和养分均总体高于未种植黄灵芝的大叶栎、红锥和火力楠人工林。大叶栎和红锥人工林下种植黄灵芝,土壤水分保持能力上升,也具备较好的土壤通气性。火力楠人工林下种植黄灵芝,土壤水分保持能力下降,空气流通受限。
In order to provide scientific basis for promoting ecological cultivation model of Ganoderma lu⁃cidum,taking Quercus griffithii,Castanopsis hystrix and Michelia macclurei plantations with two-year-old Ganoderma luteum cultivation as research objects,effect of short-term G.luteum cultivation on soil physical and chemical properties in stands were investigated.Results showed that soil bulk densities,mass water contents,capillary porosities,non-capillary porosities,total porosities,aeration capacities,capillary water-holding capacities,maximum water-holding capacities and field water-holding capacities varied to different degrees in Q.griffithii,C.hystrix and M.macclurei plantations with G.luteum.Soil non-capillary porosity in Q.griffithii plantation with G.luteum was significantly higher than that in Q.griffithii plantation without G.luteum.Soil capillary porosity and total porosity in C.hystrix plantation with G.luteum were significantly higher than those in C.hystrix plantation without G.luteum.Non-capillary porosity in C.hystrix plantation with G.luteum were significantly lower than that in C.hystrix plantation without G.luteum.Soil pH and nu⁃trients in Q.griffithii,C.hystrix and M.macclurei plantations with G.luteum were overall higher than those in Q.griffithii,C.hystrix and M.macclurei plantations without G.luteum.Q.griffithii and C.hystrix planta⁃tions with G.luteum improved soil water retention and maintained good soil aeration.M.macclurei planta⁃tion with G.luteum reduced water retention and restricted air circulation.
