甘蔗渣与牛粪不同配比对烤烟产质量的影响

摘要

为探明甘蔗渣与牛粪不同配比在烤烟生产上的应用效果,以云烟87为试验材料,设置甘蔗渣与牛粪干重比(5∶5、6∶4、7∶3)3个有机肥配方,研究其对烤烟生长、经济效益、常规化学成分和评吸质量的影响.结果表明:与只施用烤烟专用复合肥相比,施用有机肥能改善烟叶化学成分的协调性,甘蔗渣与牛粪配比有机肥的效果好于玉米秸秆与牛粪配比(6∶4),且高比例甘蔗渣有机肥处理烟叶的协调性较好,但其产量和产值较低.综合看,甘蔗渣与牛粪干重比为5∶5时烤烟的综合评价排名较高,为3.5分,其产量为116.33 kg/667m2,产值为3 261.21元/667m2,上等烟比例达81.2％.%To explore the effects of mixed application of bagasse and cow dung in flue-cured tobacco production,three proportions of bagasse to cow dung(5 ∶ 5,6 ∶ 4,7 ∶ 3) were set to explore the effects on growth,economic benefits,conventional chemical compositions and smoking quality of Yunyan 87.Results:Applying organic manure could improve the harmony of chemical components in flue-cured tobacco in comparison of applying special compound fertilizer for flue-cured tobacco.Mixed application of bagasse and cow dung had better effects than maize straw and cow dung(6 ∶ 4),high-proportion bagasse organic fertilizer was of better harmony,but lower yield and output.5 ∶ 5 of bagasse to cow dung was of higher comprehensive evaluation rank,scoring 3.5,the yield,output and first-class tobacco proportion were 116.33 kg/667m2,3 261.21Yuan/667m2 and 81.2％ respectively.
