【摘要】 为降低烤烟生产中无机肥用量,提高烤烟产量,改善烟叶品质,采用大田试验研究了有机无机肥配施对烤烟生理特性和经济性状的影响。结果表明:35%有机肥和65%无机肥配合施用下烤烟叶绿素类胡萝卜素含量、硝酸还原酶活性、根系活力相对较高,烤后烟叶的产量、均价、产值和上中等烟比例较高;但有机无机肥配施中有机肥比例过高时烤烟各生理指标会降低,经济性状也较差。更多还原

【Abstract】 The physiological characteristics and economic traits of flue-cured tobacco were studied by a field experiment to enhance yield and quality of flue-cured tobacco with low application amount of chemical fertilizers.The results showed that the chlorophyll content,carotenoid content,NR activity and root activity of flue-cured tobacco were high when fertilized with 35% organic manure combined with 65% chemical fertilizers,the yield,mean price,output value and ratio of leaves with first and middle class were higher than other treatments.The various physiological characteristics and economic traits of flue-cured tobacco were lower and worse under high rate of organic manure.更多还原
