【摘要】 为研究猪粪沼液施用对玉米产量品质及土壤理化性质的影响，选取规模化养殖场的猪粪沼液进行秋玉米种植试验。试验设置4个处理，每个处理3个重复，共12个小区，每个小区66.66 m²。对照组（CK组）施用100%化肥（50%基施+50%追施）,试验组分别施用50%化肥基施+50%沼液追施（T1组）,100%沼液基施（T2组）,100%沼液追施（T3组）。试验结果表明：1)T1组玉米产量最高，达1159.34 kg·666.67 m^-2、亩产值2782.42元，经济效益明显，产量利润分别比对照高16.06%、385.08元；2)T1、T3与对照（CK）、T2相比，单果重、产量明显增加；3)施用沼液的玉米中均不含抗生素，不会影响玉米的食用品质安全；4)水旱轮作种植中，施用沼液土壤中的理化性状不会明显改变，也不会集累重量金属等有害物质。因此，施用50%化肥基施+50%沼液追施可以明显提高玉米产量产值和利润，而且不会对玉米抗生素含量和土壤理化性质产生明显影响。更多还原

【Abstract】 To study the effects of pig manure biogas slurry application on the yield and quality of corn and the physical and chemical properties of soil.Select pig manure biogas slurry from large-scale farms to carry out autumn corn planting experiment.The experiment is set up with 4 treatments, each treatment has 3 repetitions, a total of 12 plots, each plot is 66.66 m~2.The control group(CK group) was treated with 100% chemical fertilizer(50% base application +50% topdressing), the experimental group was treated with 50% chemical fertilizer base application +50% biogas slurry topdressing(T1 group), 100% biogas slurry base application(T2 group), and 100% biogas slurry topdressing(T3 group).1) the yield of T1 group was the highest, up to 1159.34kg/666.67 m~2, and the output value per mu was 2782.42 yuan.The economic benefit was obvious, and the yield profit was 16.06% and 385.08 yuan higher than the control respectively; 2) Both CK group and T2 group would result in a significant decrease in single fruit weight and yield; 3) The application of biogas slurry in corn does not contain antibiotics, which will not affect the food quality and safety of corn; 4) During the rotation planting of flood and drought, the physical and chemical properties of the soil with biogas slurry will not change significantly, nor will it accumulate harmful substances such as heavy metals.Applying 50% chemical fertilizer base application + 50% biogas slurry topdressing can significantly improve the output value and profit of corn, and will not have a significant impact on the antibiotic content of corn and the physical and chemical properties of soil.更多还原
