摘　　要：为探究烟梗灰加工成的生物芝麻饼肥和发酵菜籽饼肥对烤烟农艺性状、抗逆性、质量及产量的影响,设置了烟梗灰生物芝麻饼肥以及菜籽饼肥3种施肥浓度梯度150、300、450 kg/hm^2的大田试验,结果表明:增施烟梗灰生物芝麻饼肥对于植株的抗逆性、农艺性状、生育周期以及经济性状的促进作用要好于菜籽发酵饼肥和传统的施肥方式(即未采用生物有机肥,对照),生育周期延长2~4 d,增加了烟叶干物质积累量;施用生物有机肥的抗逆性较传统施肥方式强,最大可降低5.10%的发病率,可使发病的病情指数下降6.21;在烟叶外观质量上,可使下部叶片增厚,增加其干物质的积累,同时使上部叶疏松,提高了上部叶的可用性;综合考虑烟叶产量与品质,生物有机肥施用量以150 kg/hm^2为宜。In order to investigate the effect of biological sesame cake and fermentation rapeseed cake on agronomic characters, stress resistance, quality, yield of flue-cured tobacco, concentration gradient of three kinds of biological organic fertilizer（ 150 kg/hm：, 300 kg/hm2 ,450 kg/hm2）were set. The results showed that increasing application of tobacco stalk ash biological sesame cake in the plant resistance, agronomic traits, economic traits and reproductive cycle effect was Better than the traditional fermented rapeseed cake fertilizer and fertilization methods （not using bio-organic fertilizer, control）, 2~4 d prolong growth cycle,increased the dry matter accumulation of tobacco leaves.Compared with traditional fertilization, the application of bio-organic fertilizer resistance maximum could decrease the incidence of 5.10% ,the disease index down 6.21 ;in appearance quality of tobacco leaf, the lower leaf thickening,increase of the dry matter accumulation, at the same time, the upper part of leaf loose,improved the usability of upper leaves ; considering the yield and quality of tobacco leaves, bio-organic fertilizer 150 kg/hm2 was appropriate.
