无机肥与有机肥配施对烟株农艺性状及烟叶产质量的影响

Effects of Combined Application of Organic and Inorganic Fertilizers on Agronomic Traits of Tobacco Plants, Yield and Quality of Tobacco leaves

为了解无机肥与商品牛粪配施对烟叶产质量的影响,采用田间试验方法,研究了商品牛粪与无机肥配合施用对烤烟植株农艺性状及烟叶产值量的影响。结果表明:商品牛粪与无机肥不同用量配合施用对烟株农艺性状的影响不明显,无机肥750kg/hm2+商品牛粪2 250kg/hm2能获得较好的经济效益,无机肥750kg/hm2+商品牛粪1 500kg/hm2对上部烟叶化学品质有一定的改善作用。烤烟大田生产中施用无机肥750kg/hm2配施商品牛粪1 500～2 250kg/hm2有利于提高烟叶的产质量和经济效益。

A field experiment was conducted to study the effects of combined application of organic and inorganic fertilizers on agronomic traits of tobacco plants, yield and quality of tobacco leaves. The results showed that combined application of various amount of organic and inorganic fertilizers had no significant influence on the agronomic traits, applying 750 kg/hm2 inorganic fertilizer＋2 250 kg/hm2 commercial cow dung could gain better economic benefits, the chemical quality of the upper leaves was improved to a certain extent when fertilized with 750 kg/hm2 inorganic fertilizer＋ 1 500 kg/hm2 commercial cow dung. In the field production, applying 750 kg/hm2 inorganic fertilizer＋1500-2 250 kg/hm2 commercial cow dung was beneficial to enhance the yield and quality of flue-cured tobacco leaves and the economic benefits.
