| 中文摘要: |
| 【目的】探寻生物有机肥在广东烟草中进行大面积推广和应用的合理施用量。【方法】利用已分
离的有益微生物菌株（Azotobacter sp. x34，Bacillus sp. jb21，Rubrivivax gelatinosus sbg11）与有机物发酵配制
而成的生物有机肥，通过大田试验，研究不同生物有机肥施用量对烟草植株的生长、叶片光合色素含量、叶片
酶活性和烟叶烤后产量产值的影响。【结果】在大田条件下，不同施用量的生物有机肥均可显著提高烟草的株
高、茎围、叶长和叶面积，提高烟草质体色素含量和代谢酶活性，也可不同程度地提高上等烟叶的比例、烟叶
产量和产值，其中 T3 处理（每株烟草基肥和追肥分别施用生物有机肥 20 g）显著促进烟草生长，株高最大提高
44.53%，产量提高 29.67%，产值提高 18.87%。【结论】中用量菌肥即每株烟草基肥和追肥分别施用生物有机肥
20 g，对烟草产量和品质的提高效果更明显，可作为此生物有机肥的推荐用量。 |

| 【Objective】The study was to explore the rational application amount of bio-organic fertilizer for its
large scale application and extension in tobacco in Guangdong.【Method】The bio-organic fertilizers were fermented with
isolated beneficial microbial strains (Azotobacter sp. X34 ; Bacillus sp. jb21 and Rubrivivax gelatinosus sbg11) and organic
matter. The effects of different amounts of bio-organic fertilizers on tobacco growth, leaf photosynthetic pigment content,
leaf enzyme activity, and the yield and output value of flue-cured tobacco were studied through field tests.【Result】Under
field conditions, different application amounts of bacterial fertilizers could significantly improve tobacco plant height, stem
girth, leaf length and leaf area, promote tobacco photosynthetic pigment content and metabolic enzyme activity, and increase
the proportion of superior tobacco leaf and yield and output value of tobacco leaf. T3 treatment(the application amounts forbase fertilizer and top dressing were 20 g per plant respectively) significantly promoted the growth of tobacco, with the highest
increase in plant height (44.53%). The yield and output value of T3 treatment increased by 29.67% and 18.87%, respectively.
【Conclusion】The application amount of bacterial fertilizer in T3 (in which 20g bacterial fertilizers were applied for base
fertilizer and top dressing per plant respectively) can increase the yield and quality of tobacco obviously, and can be used as the
recommended dosage of fertilizer. |
