有机无机肥配施对烟叶综合效益的影响

Effects of Chemical Fertilizer Combined with Organic Manure Fertilizer on Comprehensive Benefit of Flue-cured Tobacco

为节约肥料成本、改善烟叶品质,在川北烟区开展了单施化肥、有机肥与化肥配施对烤烟农艺、烟叶经济性状和质量性状的影响研究。结果表明,有机无机肥配合施用能显著改善烟叶生长,提高打顶后烟株农艺性状指标;有机无机肥配合施用较单施无机化学肥料处理烟叶产量增加9.3%,产值增加12.1%,中上等烟叶所占比例提高6.6%,节本增收5 735.3元/hm2。因此,川北烟区烤烟种植时应重视有机肥的施用。

In order to save fertilizer cost and increase quality of flue-cured tobacco in Chuanbei area of northern Sichuan,field experiment was conducted to investigate the agronomic properties, yield, market value, smoking quality and economic benefit of flue-cured tobacco by applying different type of fertilizers. The results indicated that the growth potential of tobacco plants effectively enhanced under the chemical fertilizer combined with organic manure fertilizer. The yield and market value of flue-cured tobacco under the chemical fertilizer combined with organic manure fertilizer increased by 9.3% and12.1% compared with the only applying chemical fertilizer treatment. The proportion of high-quality leaves under the treatment of combination chemical with organic manure fertilizers increased by 6.6%, and increasing economic output by 5 735.3yuan per hectare. It suggested that the quality of tobacco leaves was greatly improved after using chemical fertilizer combined with organic manure fertilizer, and this fertilization mode could be popularized in large scale in the tobacco cultivation of Chuanbei area.
