摘　　要：为研究玉米在不同种植密度下,沼肥(液)不同用量对玉米生长和产量形成的影响,开展3个种植密度3种沼肥施用量试验。结果表明,玉米在A_1、A_2密度下,玉米产量随沼肥(液)施用量的增加而增加,但在A_3密度下,沼肥(液)施用量越大玉米产量反而降低,产量与经济效益表现最优的是A_2B_3、A_1B_3处理,即当玉米群体密度分别为5069株/667m^2,4535株/667m^2,沼肥用量为1111.7kg/667m^2。In order to explore the effect of different planting density and biogas manure amount application on the growth and yield of maize,a test of 3 density levels and 3 biogas manure amount levels was conducted. The results showed that under the density of A1 and A2,the yield of maize was increase by the increase of biogas manure. But when density reached by A3,the larger amount of biogas manure,the lower yield. The highest yield and economic income treatments was A2B3 and A1B3,namely the density was 5069plants/667m^2,4535plants/667m^2,used 1111. 7kg/667m^2 biogas manure.
