稻茬烤烟优化基肥和提苗肥对上部烟叶经济性状和品质的影响
Effects of Optimizing Fertilizer for Base and Raising Seedlings Fertilizer on Economic Characters and Qual-ity of Upper Leaves of Paddy-tobacco
摘要
Abstract
In order to improve the quality and economic characters of the upper leaves of paddy-tobacco,with Yunyan 87 as the ex-perimental material,the two-factor experiment was conducted to study the effects of optimizing base fertilizer(adding microbial agents to base fertilizer)and optimize raising seedlings fertilizer(seedling-raising fertilizer combined with urea)on the economic characters,physical properties,chemical composition and smoking quality of flue-cured tobacco.The results showed that the yield and output value of the upper tobacco leaves were increased by adding microbial agent to base fertilizer,and single leaf quality,leaf thickness,leaf area quality and total sugar content of upper tobacco leaves were improved by applying urea as seedling-raising fertilizer.Be-tween the treatment of adding microbial agents to base fertilizer and seedling-raising fertilizer combined with urea,the economic character index of the upper leaves increased by 11.53%,the total score of smoking quality increased by 16.14%,and the compre-hensive effect index increased by 9.64%,compared with that of no microbial agent and single application of seedling-raising fertilizer for tobacco.Generally speaking,base fertilizer added microbial agent and appropriate amount of urea applied in seedling-raising fer-tilizer were beneficial to improve the yield,output value and quality of upper tobacco leaves.关键词
