不同比例有机肥与化肥配施对烤烟生长及产质量的影响

Effect of Different Proportion of Organic and Chemical Fertilizer on Tobacco Growth and Leaf Quality

【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。

[ 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 %.
