摘　　要：在雷竹林传统施肥方式的基础上配施不同类型的有机肥(经发酵的杏鲍菇渣、鸭粪和猪粪),探究有机肥对土壤有效养分含量的影响。结果表明,施用3种有机肥的雷竹林耕作层(0~20 cm)土壤水解氮、速效磷、速效钾含量,均以施猪粪肥的为最高,施用杏鲍菇渣肥的土壤只有速效钾含量高于鸭粪肥,其他均低于鸭粪肥;不同有机肥类型对土壤氮、磷、钾等有效养分的改善效果存在季节差异。因此,当雷竹林地施用杏鲍菇渣肥时,可以增加鸭粪或猪粪有机肥用量配比,以增强土壤养分有效性的效果。The paper studies the effect of organic fertilizers on the contents of soil available nutrients by applying different kinds of organic fertilizer, i.e., fermented Pleurotus ergngii residues, duck manure and pig manure, on the base of conventional fertilization. The results show that the contents of hydrolytic nitrogen, available phosphorus and available potassium in the topsoil(0-20 cm) are highest with the application of pig manure, while in the soil where fermented P. eryngii residues are applied, only the content of available potassium is higher than that with duck manure. Different kinds of organic fertilizer have different effect on the efficiency improvement of the 3 nutrients in different seasons. Therefore, it is suggested to add duck or pig manure to some ratio when P. ergngii residues are applied in Ph. praecox stands so as to improve the efficiency of soil available nutrients.
