摘　　要：沼液含有植物生长所需的多种营养元素。为明确沼液在鲜食糯玉米上的应用效果,采用盆栽试验,研究了沼液施用量对鲜食糯玉米植物学性状及产量的影响。结果表明,鲜食糯玉米的株高、茎粗、穗位高、穗长和鲜穗产量等指标随沼液施用量的增加而增加,沼液施用量为120000 kg/hm^(2)时各指标达到最高,沼液施用量为135000 kg/hm^(2)时各指标表现为降低,说明适宜用量的沼液能够促进玉米生长发育,过量施用沼液则表现为一定的抑制作用。综合分析可知,在鲜食糯玉米生产中,沼液施用量应控制在120000 kg/hm^(2)左右为宜。Biogas slurry contains various nutrients required for plant growth.In order to clarify the application effect of biogas slurry on fresh waxy corn,the pot experiment was conducted to study the effect of biogas slurry application rate on botanical character and yield of fresh waxy corn.The results showed that the indexes of plant height,stem diameter,ear height,ear length and fresh ear yield of fresh waxy corn increased with the increase of biogas slurry application rate.When the biogas slurry application rate was 120000 kg/hm^(2),the indexes reached the highest level,and when the biogas slurry application rate was 135000 kg/hm^(2),the indexes reached the lowest level.It indicated that the appropriate application rate of biogas slurry could promote the growth and development of corn,while excessive application of biogas slurry showed a certain inhibition effect.Through comprehensive analysis,it can be determined that the biogas slurry application rate in the production of fresh waxy corn should be controlled at about 120000 kg/hm^(2).
