'恩格兰'牌系列微生物有机肥在烤烟中效应研究

摘要

Objective] This study was conducted to provide theoretic support for im-proving yield and quality of flue-cured tobacco by applying microbial organic fertiliz-ers. [Method] A field plot experiment was conducted to study the effects of the En-gran series of microbial organic fertilizers on growth and development, diseases and pests and economic traits of flue-cured tobacco. [Result] The result showed that the treatment of conventional fertilization + Engran microbial agent could promote the growth and dry matter accumulation of flue-cured tobacco during the growth period in the field, enhance the disease resistance of tobacco, and improve yield and out-put value of flue-cured tobacco and income of tobacco growers. Compared with T1, the proportion of high-grade tobacco, the proportion of mid-high grade tobacco, yield, output value and average price increased by 4.4%, 3.8%, 5.48%, 11.51% and 5.73% respectively. [Conclusion] The treatment of conventional fertilization + Engran microbial agent showed outstanding performance, is optimum for field production, and could be applied to Flue-cured tobacco.%[目的]为烟草生产中施用微生物有机肥等肥料提高烤烟的产质量提供理论技术支持。[方法]通过田间对比试验，研究了"恩格兰"牌系列微生物有机肥对烤烟生长发育、烟草病虫害及烤烟经济性状的影响。[结果]研究表明，常规施肥+恩格兰微生物菌剂处理在大田生育期能促进烤烟生长发育及烤烟干物质积累，增强烟株的抗病能力，提高烤烟的产量、产值及烟农收入。和 T1相比，上等烟比例、上中等烟比例、产量、产值和均价分别提高了4.4%、3.8%、5.48%、11.51%和5.73%。[结论]常规施肥+恩格兰微生物菌剂处理表现突出，最适宜大田生产，可在烤烟上推广应用。
