邦禾生物有机肥对烟叶产质量的影响

目的]探讨邦禾生物有机肥在烤烟生产上的应用效果。方法]于2013~2015年在邵武市沿山不同海拔区域开展邦禾生物有机肥和常规施肥对照的大田生产示范试验,研究邦禾生物有机肥对烤烟生长发育、产量和质量的影响。结果]与常规施肥相比,施用邦禾生物有机肥能够促进烟株生长发育且顶叶开面效果好,对花叶病、青枯病、赤星病具有一定防治作用;施用邦禾生物有机肥的烤烟经济性状表现较优,可有效地降低烤烟烟碱含量,提高烤烟总糖、还原糖含量,使内在化学成分更趋于协调,但烤烟产量提高不明显。结论]邦禾生物有机肥可用于烤烟生产,应进一步对邦禾生物有机肥进行不同施用量的梯度试验,为生物有机肥在烤烟生产中的推广应用提供技术支持。

Effect of Backer Bio-organic Fertilizer on Tobacco Yield and Quality

Objective] The aim was to discuss the application effect of backer bio-organic fertilizer in flue-cured tobacco production.Method] The field production demonstration experiment by applying backer bio-organic fertilizer and conventional fertilizer was conducted in different alti-tude region along the mountain in Shaowu City during 2013-2015, effects of backer bio-organic fertilizer on growth, yield and quality of flue-cured tobacco were studied.Result] Compared with the conventional fertilization, application of backer bio-organic fertilizer could promote the growth of tobacco plant, also had a preventive effect on mosaic, bacterial wilt, alternaria altemata;The economic characters of flue-cured tobacco with backer organic fertilizer could effectively reduce nicotine content, increase total sugar and reducing sugar content, and make the internal chemical composition more harmonious, but the yield of flue-cured tobacco was not increased obviously.Conclusion] Backer bio-organic fertil-izer can be used in flue-cured tobacco production, gradient experiment with different dosages of backer bio-organic fertilizer should be conducted, which can provide technical support for application of bio-organic fertilizer in flue-cured tobacco production.
