不同比例有机肥与化肥配施对烤烟生长及产质量的影响

摘要

[Objective]The effects of different ratio of organic and inorganic fertilizers on the growth and the influence of yield and quality of flue-cured tobacco was studied.[Method] Using randomized blocks design,the data of the test materials K326 were analyzed by using variance analysis,significance test and other methods.[Result]The release efficiency of organic fertilizer in the soil was slower,and the effects of organic fertilizer on the growth of tobacco plants was worse than that of chemical fertilizers,25 ％ organic fertilizer + 75 ％ chemical fertilizer on the quality of the flue-cured tobacco was better.The treatment of 50 ％ organic fertilizer + 50 ％ chemical fertilizer had high processing production of flue-cured tobacco and high proportion of superior tobacco.[Conclusion] The ratio of organic fertilizer in the agricultural production was better with 25 ％-50 ％.%[目的]探究不同有机无机肥料配比对烤烟生长和产质量的影响.[方法]以K326为试验材料,采用随机区组设计,通过方差分析和显著性检验进行研究.[结果]有机肥料在土壤中的释放效率较慢,对烟株的生长效果不如施用化肥处理;25％有机肥+75％化肥处理对烤烟的品质较好,50％有机肥+50％化肥处理的烤烟产量、上等烟比例较高.[结论]建议农业生产中有机肥使用比例以25％～50％为宜.
