摘　　要：通过田间试验,研究了不施肥处理(CK)、风干鸡粪(CM)、有机无机复合肥(OIC)和生态有机肥(BIO)处理对定植大果榉(Zelkova sinica)土壤碱解氮和有机质含量,土壤微生物量碳氮含量以及大果榉地上部生长指标(株高、胸径和叶面积)增长率的影响。结果表明:与CK相比CM、OIC和BIO处理均增加了土壤碱解氮和有机质含量,显著提高土壤微生物量碳、氮的含量,其中BIO处理的土壤微生物量碳氮含量最高;与CM和OIC处理相比,BIO处理初期土壤碱解氮含量相对较低,而有机质含量在整个观测期均表现出较高水平;各施肥处理均显著提高了大果榉株高、胸径和叶面积增长率,其中BIO和OIC处理效果较好。Field trials of organic farming were conducted to examine the effects of different fertilizer treatments on the soil available nitrogen,organic matter,soil microbial biomass carbon and nitrogen contents,and the growth of Zelkova sinica.No fertilization treatment(CK),chicken manure treatment(CM),organicinorganic compound fertilizer treatment(OIC)and ecological organic fertilizer treatment(BIO)were included.The Results indicated that the contents of soil available nitrogen and soil organic matter(treatments of CM,OIC and BIO)were all increased compared with the treatment of CK,both of soil microbial biomass carbon and nitrogen contents were significantly improved,especially in the treatment of BIO.In this BIO treatment,the content of soil available nitrogen was lower than others in the early period,but the soil organic matter was the highest in the whole duration,when compared with treatments of CM and OIC.Additonally,the growth rate of plant height,diameter of breast height and leaf growth of Zelkova sinica were improved under these three treatments(CM,OIC and BIO),and the growth of Zelkova sinica performed better under treatments of BIO and OIC,especially.
