微生物菌肥对烤烟生长发育和品质的影响

Effects of Different Microbial Fertilizer on Growth and Development and Quality of Flue-Cured Tobacco

为了提高烟叶产量、提升烟叶品质以及筛选适宜的微生物菌肥,通过田间试验研究了不同微生物菌肥对烤烟生长发育、产量和质量的影响。结果表明,施用微生物菌肥明显提高了烟株高度、有效叶片数、最大叶面积和叶绿素含量,产量和产值分别增加了11.29%~17.80%和15.80%~26.57%,改善了烟叶化学成分的协调性,提高了烟叶钾含量;其中农夫喜力复合微生物菌剂等4种微生物菌肥混合施用在丘北烟区烟叶生产中的效果较理想。

In order to improve the yield and quality of tobacco, as well as screen the suitable microbial fertilizer, a field experiment was conducted to study the influences of different kinds of microbial fertilizers on the growth and development,yield and quality of flue-cured tobacco. The results showed that the application of microbial fertilizers significantly promoted the plant height, effective leaves, the largest leaf area and content of chlorophyll, and increased the yield and output by 11.29% to 17.80% and 15.80% to 26.57% respectively. The chemical composition was more coordinate; and the potassium content was enhanced after applying the microbial fertilizer. The Nongfuxili complex microorganisms and mixed 4 kinds of microorganisms were suitable for the flue-cured tobacco production in Qiubei tobacco-planting area.
