不同有机肥对有机生态烟叶生长及品质的影响

Effect of Different Organic Fertilizers on the Growth and Quality of Organic Flue-cured Tobacco

为了探究适宜有机生态烟叶生产的有机肥,在贵州省威宁县特定的有机烟叶生产环境下,通过田间小区试验,研究了不同有机肥对烤烟生长及品质的影响。结果表明:在一垄双行栽培模式下,施用有机肥的有机生态烟的大田生育期明显比传统施肥烟的缩短,根系活力在生育前期增强,抗病能力提高;烟叶外观质量、内在质量得到改善,烟叶物理特性与加工性能得到提高;烟叶内在化学成分更为协调;烟叶的工业可用性大大增强。在3种有机肥中(未发酵油枯、发酵充分油枯、氨基酸有机肥与油枯混合)以施用发酵油枯+农家肥的处理综合表现最好,优于其他2种有机肥。

Effect of different organic fertilizers on the growth and quality of organic flue-cured tobacco was studied by field experiments to find suitable organic fertilizer in the specific conditions in Weining county,Guizhou.The results showed that under the cultivation mode of two rows in a ridge,the growth period of the organic flue-cured tobacco applied with organic fertilizer was obviously shorter than conventional cultivation,root activity was enhanced in early-growth stage,and the disease resistance was also improved.The appearance quality and quality were improved,and physical property and processing ability were also promoted.Chemical compositions were harmonized,and the industrial usability was significantly increased.The effect of fermented soybean cakes conbined with farm manure was the best among the three organic fertilizer sources treatments named unfermented soybean cakes,fermented soybean cakes,and mixture of amino acid organic fertilizers and soybean cakes.
