摘　　要：采用田间小区试验,研究了猪粪型有机肥配施无机肥对春玉米地土壤养分含量和春玉米产量的影响。结果表明:与等养分含量的无机肥相比,猪粪型有机肥配施无机肥可以提高春玉米生长期土壤速效氮、速效磷的含量,但对速效K含量影响不明显;猪粪型有机肥可以提高春玉米百粒重、产量和植株地上部干物质量。其中以化肥和猪粪堆肥配合施用(化肥N占90%,有机肥N占10%)处理效果最好。The effects of combined application of pig manure type of organic fertilizer and inorganic fertilizer on soil fertility and yield of spring maize were studied by using field plot experiment.The results showed that in comparison with inorganic fertilizer with the same amount of nutrition,combined application of pig manure type of organic fertilizer and inorganic fertilizer can increase the contents of soil available N and soil available P but no significant affection on soil available K during the growing time of spring maize;pig manure type organic fertilizer can increase the 100-seeds weight,the yield and the dry matters in plant aerial part of spring maize;among all of the treatments,the combined application of chemical fertilizer and pig manure composting（chemical N fertilizer account for 90% and organic N fertilizer account for 10%） had the best effect.
