猪粪沼液替代部分化肥对鲜食玉米产质量及土壤性状的影响
Effects of Chemical Fertilizer Reduction Combined with Pig Manure Biogas Slurry Application on the Yield and Quality of Fresh Maize and Soil Properties
摘要
Abstract
This study aims to explore the yield-increasing and efficacy-enhancing effects of chemical fertilizer reduction combined with pig manure biogas slurry application in the production of fresh maize.The fresh maize cultivar'Jintaiyang 8'was planted and subjected to five treatments:no fertilization(NF),conventional fertilization(CF),optimized fertilization(OF),biogas slurry replacing 15%chemical fertilizer(M15%),and biogas slurry replacing 30%chemical fertilizer(M30%).The results showed that compared with CF,OF,M15%,and M30%increased the economic yield of fresh maize by 1 815,1 215 and 1 875 kg/hm2,reduced the chemical fertilizer cost by 870,1 755 and 2 655 yuan/hm2,and increased the output value by 7 260,4 860,and 7 500 yuan/hm2,respectively.In addition,M15%and M30%significantly increased the reducing sugar content in fresh maize and improved the available nutrient content,total nutrient content,and fertility of soil.The application of pig manure biogas slurry serves as an effective measure in reducing chemical fertilizer,improving quality,and enhancing production efficiency.Among the treatments,M30%demonstrates the best performance.关键词
